In that most largely used, known as " creosoting," dead oil of tar, to the amount of some 3 gallons per sleeper, is forced into the wood under pressure, or is sucked in by vacuum, both the timber and the oil being heated.
The rails, which for heavy main line traffic may weigh as much as too lb per yard, or even more, are rolled in lengths of from 30 to 60 ft., and sleepers are placed under them at intervals of between 2 and 3 ft.
The unit of power commonly used by engineers is the horse-power, and this unit corresponds to a rate of working of 550 foot-lb of work per second.
If the total resistance against which the train is maintained in motion with an instantaneous velocity of V feet per second is R, the rate at which energy is expended in moving the train is represented by the product RV, and this must be the rate at which energy is supplied to the train after deducting all losses due to transmission from the source of power.
The rate at which work is done on a particular axle is measured by the product where T is the torque or turning moment exerted on the axle by the motor or mechanism applied to it for this purpose, and is the angular velocity of the axle in radians per second.
If the speed is given in miles per hour, S say, V =1.466 S (6) The revolutions of the axle per second, n, are connected with the radians turned through per second by the relation n =w/27r = w/6.38 (7) § 2.
Let E represent the pounds of coal burnt per hour in the fire-box of a locomotive, and let c be the calorific value in B.Th.U.
Let p be the mean pressure in pounds per square inch, calculated from an indicator diagram taken from a particular cylinder when the speed of the crank-shaft is n revolutions per second.
This corrected pull is then divided by the weight of the vehicles hauled, in which must be included the weight of the dynamometer car, and the quotient gives the resistance per ton of load hauled at a certain uniform speed on a straight and level road.
From Aspinall's experiments it appears to be about 17 lb per ton, and this value is plotted on the diagram.
Thus a gradient of I in 200 is the same as a half per cent.
The maximum rate of combustion may be as much as so lb of coal per square foot of grate per hour, and in exceptional cases even a greater rate than this has been maintained.
A few experimental results are set forth in Table XX., from which it will be seen that with a relatively low rate of combustion, a rate which denotes very light service, namely lb of coal per square foot of grate per hour, the efficiency of the boiler is %, which is as good a result as can be obtained with the best class of stationary boiler or marine boiler even when using economizers.
The exhaust steam passing from the engine through the blastpipe and the chimney produces a diminution of pressure, or partial vacuum, in the smoke-box roughly proportional to the weight of steam discharged per unit of time.
Then the work done during one revolution of the crank is 2pla per cylinder.
Assuming that the mean pressure in the other cylinder is also p, the total work done per revolution is 4pla.
If T is the mean torque, the work done on the crank-axle per revolution is 27rT.
Let the boiler pressure be 175 lb per square inch.
Taking 85% of this, the maximum mean effective pressure would be 149 lb per square inch.
This would be distributed between three coupled axles giving an average of 1.38 tons per axle, though the distribution might not in practice be uniform, a larger proportion of the weight falling on the driving-axle.
The engine can only exert this large tractive force so long as the mean pressure is maintained at 149 lb per square inch.
This high mean pressure cannot be maintained for long, because as the speed increases the demand for steam per unit of time increases, so that cut-off must take place earlier and earlier in the stroke, the limiting steady speed being attained when the rate at which steam is supplied to the cylinders is adjusted by the cut-off to be equal to the maximum rate at which the boiler can produce steam, which depends upon the maximum rate at which coal can be burnt per square foot of grate.
If C is the number of pounds of coal burnt per square foot of grate per hour, the calorific value of which is c B.Th.U.
If h is the water heat at the lower temperature, h l the water heat at the higher temperature, and L the latent heat at the higher temperature, the heat supply per pound of steam is equal to h1 - h2+L1, which, from the steam tables, with the values of the temperatures given, is equal to 1013 B.Th.U.
When the initial pressure is 100 lb per square inch by the gauge the thermal efficiency drops to about nearly 15% with the same back pressure.
The expression for the indicated horse-power may be written I.H.P. =pay/550 (27) where v is the average piston speed in feet per second.
In a particular case where the boiler pressure was maintained constant at 130 lb per square inch, and the cut-off was approximately 20% of the stroke, the values c =55 and b=o 031 were deduced, from which it will be found that the value of the piston speed corresponding to the maximum horsepower is 887 ft.
In compound working the combined volumes of the low-pressure cylinders is a measure of the power of the engine, since this represents the final volume of the steam used per stroke.
In Hungary and Russia a zone-tariff system is in operation, whereby the charge per mile decreases progressively with the length of the journey, the traveller paying according to the number of zones he has passed through and not simply according to the distance traversed.
On the other hand, where, as in America, the great volume of freight is raw material and crude food-stuffs, and the distances are great, a low charge per unit of transportation is more important than any consideration such as quickness of delivery; therefore full car-loads of freight are massed into enormous trains, which run unbroken for distances of perhaps 1000 m.
Intra-urban railways, as compared with ordinary railways, are characterized by shortness of length, great cost per mile, and by a traffic almost exclusively passenger, the burden of which is enormously heavy.
The maximum 1st, 2nd and 3rd class passenger fares are, per kilometre, 067 f.
As far as possible, these railways are laid beside roads, in preference to independent formation; the permanent way costs £977 per mile in the former as against £793 in the latter.
If laid in paving, the price varies between £1108 and £2266 per mile.
In the towns a deeper rail is used, weighing about 60 lb per yard.
The total cost per mile of such a line, including all bolts, nuts, fish-plates and fastenings, ready for laying,, delivered in the United Kingdom, is under Soo a mile.
He wrote (1) Antapodoseos, seu rerum per Europem gestarum, Libri VI, an historical narrative, relating to the events from 887 to 949, compiled with the object of avenging himself upon Berengar and Willa his queen; (2) Historia Ottonis, a work of greater impartiality and merit, unfortunately covering only the years from 960 to 964; and (3) the Relatio de Legatione Constantinopolitana (968-969).
In 1909 in the amount of barley per acre (38 bushels) Nevada ranked third, and in the average farm price per bushel ($0.75) ranked first among the barley-producing states of the country, but in the total amount produced (304,000 bushels) held only the twenty-second place; and in the same year the average yield of potatoes per acre in Nevada was 180 bushels, exceeded in two states - the average for the entire country was 106.8 bushels per acre - but the total crop in Nevada (540,000 bushels) was smaller than in any state or Territory of the Union, except New Mexico.
In 1920 he vetoed a bill calling for censorship of moving pictures and likewise a bill to permit the sale of " 2.7 5 per cent " beer.
The cost of operations amounted to an initial expenditure of 6.25 francs, and an annual expenditure of about 2.3 francs per head of the population.
Thomsen by direct experiment found that the heat-capacity of a dilute aqueous solution diverged in general less than i per cent.
Since thermochemical measurements of this type may be frequently performed with an error due to other causes of much less than i per cent., the error introduced by either of these assumptions is the chief cause of uncertainty in the method.
The observed heat of combustion of sugar is, however, 1354000, so that the error of the rule is here 20 per cent.
Some idea of the business efficiency of the C.R.B., as it was familiarly called, may be gained from the fact that although almost $1,000,000,000 was expended on food and transportation, only about one-half of one per cent was required for overhead expenses.

It is quite possible for a hot dry season to be associated with a large yield of corn, provided the drought is confined to a suitable period, as was the case in 1896 and still more so in 1898; the English wheat crops in those years were probably the biggest in yield per acre that had been harvested since 1868, which is always looked back upon as a remarkable year for wheat.
The drought of 1898 was interrupted by copious rains in June, and these falling on a warm soil led to a rapid growth of grass and, as measured by yield per acre, an exceedingly heavy crop of hay.
These prices are per imperial quarter, - that is, 480 lb of wheat, 400 lb of barley and 312 lb of oats, representing 60 lb, 50 lb and 39 lb per bushel respectively.
By dividing the total production, say of wheat, in each county by the number of acres of wheat as returned by the occupiers on June 4, the estimated average yield per acre is obtained.
It is important to notice that the figures relating to total production and yield per acre are only estimates, and it is not claimed for them that they are anything more.
The total produce of any crop in a given year must depend mainly upon the acreage grown, whilst the average yield per acre will be determined chiefly by the character of the season.
The effects of a prolonged [[Table Ix]].-Estimated Annual Average Yield per Acre of Crops in spring and summer drought, like that of 1893, are exemplified in the circumstance that four corn crops and the two hay crops all registered very low average yields that year, viz.
The mean values at the foot of the table-they are not, strictly speaking, exact averages-indicate the average yields per acre in the United Kingdom to be about 31 bushels of wheat, 33 bushels of barley, 40 bushels of oats, 28 bushels of beans, 26 bushels of peas, 44 tons of potatoes, 134 tons of turnips and swedes, 184 tons of mangels, 32 cwt.
The general average yields of the corn crops are not fairly comparable one with the other, because they are given by measure and not by weight, whereas the weight per bushel varies considerably.
The figure denoting the general average yield per acre of any class of crop needs readjustment after every successive harvest.
A large expansion in the acreage of the wheat crop would probably be attended by a decline in the average yield per acre, for when a United Kingdom, 1895-1904.
Even without manure the average produce over forty-six years, 1852-1897, was nearly thirteen bushels per acre, or about the average yield per acre of 1 The higher yield of wheat in the later years of the 19th century appears to be largely attributable to better grain-growing seasons.
In one case, indeed, the average produce by mixed minerals and nitrogenous manure was more than that by the annual application of farmyard manure; and in seven out of the ten cases in which such mixtures were used the average yield per acre was from over two to over eight bushels more than the average yield of the United Kingdom (assuming this to be about twenty-eight bushels of 60 lb per bushel) under ordinary rotation.
It is the leguminous fodder crops-especially clover, which has a much more extended period of growth, and much wider range of collection within the soil and subsoil, than any of the other crops of the rotation-that yield in their produce the largest amount of nitrogen per acre.

In the case of proposed drainage improvements, notice in writing must be given to the landlord, who may then execute the improvements himself and charge the tenant with interest not exceeding 5% per annum on the outlay, or such annual instalments, payable for a period of twenty-five years, and recoverable as rent, as will repay the outlay, with interest at the rate of 3% a year.
Three to four inches of rain per month is the average.
It is paid for at the rate of from 45 to cents per cwt.

The average yield of lint per " saw " in the United States, when working under perfect conditions, is about 6 lb per hour.
Cotton seed meal, in the absence of sufficient stock to consume it, is also used extensively as a fertilizer, and for this purpose it is worth, determining the price on the same basis as used above for the seed, from $19 to $20 per ton.
From 'goo to 1905 the crop was about ioo,000 bales per annum; the whole is consumed in local mills, and cotton is imported also from the United States.
The table indicates the chief cottonproducing islands, the acreage in each, yield, average value per pound and total value of the crop in 1905-1906.
The low yield per acre in this island, and also the low value of the lint per lb compared with the Sea Island cotton, is clearly apparent.
A considerable amount is used locally, and during the six years ending in 1907 the surplus exported ranged from about 24,000 to 40,000 bales per annum.
Against the common view that miracles can attest the truth of a divine revelation Gerhard maintained that " per miracula non possunt probari oracula "; and Hopfner returns to the qualified position of Augustine when he describes them as praeter et supra naturae ordinem."
They need not be horizontal, and sometimes have a dip of a few feet per mile, as in the case of the Ohio and Indiana oil fields, where the amount varies from one to ten feet.
Contractors will often undertake to drill wells of moderate depth at 90 cents to $1 per foot, but the cost of a deep well may amount to as much as $7000.
The authorities for the Crusades have been collected in Bongars, Gesta Dei per Francos (Hanover, 1611) (incomplete); Michaud, Bibliotheque des croisades (Paris, 1829) (containing translations of select passages in the authorities); the Recueil des historiens des croisades, published by the Academie des Inscriptions (Paris, 1841 onwards) (the best general collection, containing many of the Latin, Greek, Arabic and Armenian authorities, and also the text of the assizes; but sometimes poorly edited and still .incomplete); and the publications of the Societe de l'Orient Latin (founded in 1875), especially the Archives, of which two volumes were published in 1881 and 1884, and the volumes of the Revue, published yearly from 1893 to 1902, and containing not only new texts, but articles and reviews of books which are of great service.
The minor authorities for the Fifth Crusade have been collected by Rohricht, in the publications of the Societe de l'Orient Latin for 1879 and 1882; the ten valuable letters of Oliver, bishop of Paderborn, and the Historia Damiettina, based on these letters, have also been edited by Rohricht in the Westdeutsche Zeitschrift per Geschichte and Kunst (1891).

During 1897 the death-rate for the whole province rose to sixty-nine per thousand, or double the average, while the birth-rate fell to twenty-seven per thousand.
This controversy was unfinished when Dalton published the first part of his New System of Chemical Philosophy in 1808, although the per saltum theory was the most popular.
Thus a normal solution of sodium carbonate contains 53 grammes per litre, of sodium hydrate 40 grammes, of hydrochloric acid 36.5 grammes, and so on.
Wagnerian harmony is, then, neither a side-issue nor a progress per saltum, but a leading current in the stream of musical evolution.
In convocation, when the supremacy was discussed (11th of February 1531), he declared that acceptance would cause the clergy "to be hissed out of the society of God's holy Catholic Church"; and it was his influence that brought in the saving clause, quantum per legem Dei licet.
Agriculture is better conducted than in most of the departments of France, and the average yield per acre is greater.
To meet the cost of this Captain Fox suggested that each member should give a penny per week.
The expenses were met by collections made in the Calvinistic Methodist Societies, and as the funds increased masters were multiplied, until in 1786 Charles had seven masters to whom he paid £io per annum; in 1787, twelve; in 1789, fifteen; in 1794, twenty.
In good seasons and exceptional localities the yield may approach a bale per acre, as in Assumption parish, and in the Mississippi valley at the junction of Louisiana, Mississippi and Arkansas.
The irrigated rice area increased 92.9% from 1899 to 1902, and the construction cost of irrigation works ($4747,359 in 1902; $12.25 per irrigated acre) 87.7% in the same years.

In this manner an annuity of £T159,500 was set free, of which £Ti i,000 per annum was allotted as " extraordinary sinking fund " to series A and £T49,500 per annum each to series B, C and D; the lottery bonds were originally excluded from this arrangement, and special compensation was granted to these later.
Series B, C and D (series A having already been completely redeemed by the action of the sinking fund) were replaced by the creation of new 4% bonds to a nominal amount of £T32,738,772, with a sinking fund of 0.45% per annum, bearing identical rights and privileges, and ranking immediately after, the priority bonds.
For its privileges the regie has to pay a rent of £T750,000 per annum to the government (assigned to bondholders), " even if it has no revenues at all," and after the payment of a dividend of 8% to its shareholders, and certain other deductions, it has to share profits with the government and the bondholders according to a sliding scale agreed upon between the three parties.

The density of population increased from 16.5 per sq.
Tracing, then, the quantities of oil given per 1,000 fish from year to year, they seemed to establish a connexion between the variation in " condition " of the fish, the variation in the inflow of Atlantic water, and the variation in the number of sunspots from year to year.
It appeared that the quantity of oil contained in the liver of a cod (per unit of weight) increases with the age of the fish.

Regarding the current as the passage of a certain amount of electricity per second, it will be seen that the results FIG.
The conductivity gives us the amount of electricity conveyed per second under a definite electromotive force.
On the view of the process of conduction described above, the amount of electricity conveyed per second is measured by the product of the number of ions, known from the concentration of the solution, the charge carried by each of them, and the velocity with which, on the average, they move through the liquid.
Corresponding with this result we find that the freezing point of dilute solutions indicates that two pressure-producing particles per molecule are present.
Let x be the number of molecules which dissociate per second when the number of undissociated molecules in unit volume is unity, then in a dilute solution where the molecules do not interfere with each other, xp is the number when the concentration is p. Recombination can only occur when two ions meet, and since the frequency with which this will happen is, in dilute solution, proportional to the square of the ionic concentration, we shall get for the number of molecules re-formed in one second ye where q is the number of dissociated molecules in one cubic centimetre.
The yield of rubber varies, but it is stated on an average to be Io lb of rubber per tree, and if carefully tapped one tree will yield this amount for many years in succession.
The annual yield of rubber is rather more than 1 lb per tree.
The trees are tapped when about ten years old, and as a rule annually furnish from 5-10 lb of rubber per tree.
The blocks are cut into thin sheets by means of a sharp knife, which is caused to move to and fro about two thousand times per minute, the knife being kept moistened with water, and the block fed up to it by mechanical means.

In 1824 the settled indigenes had to pay the very heavy rate of 11 roubles (about 1) per head, and the arrears, which soon became equal to the sums levied, were rigorously exacted.
The natural rate of increase of population is very slow as a rule, and does not exceed 7 or 8 per 1000 annually.
Industrial surveys, having for their object the granting of land to the peasants to the extent of 40 acres per each male head, with 8 additional acres of wood and 8 acres as a reserve, were started many years ago, and after being stopped in 1887 were commenced again in 1898.
In the same address he called attention to the conditions of the world's food supply, urging that with the low yield at present realized per acre the supply of wheat would within a comparatively short time cease to be equal to the demand caused by increasing population, and that since nitrogenous manures are essential for an increase in the yield, the hope of averting starvation, as regards those races for whom wheat is a staple food, depended on the ability of the chemist to find an artificial method for fixing the nitrogen of the air.
The population of Lower Austria in 1900 was 3,100,493, which corresponds to 405 inhabitants per sq.
The pulse is slowed, the number of beats per minute being actually reduced, under considerable doses, to forty, or even thirty, per minute.
The latest result is 299,860 kilometres per second, with a probable error of perhaps 30 kilometres - that is, about the ten-thousandth part of the quantity itself.
Hence if the induction per square centimetre at any point is denoted by B, then in empty space B is numerically equal to H; moreover in isotropic media both have the same direction, and for these reasons it is often said that in empty space (and practically in air and other nonmagnetic substances) B and H are identical.
The induction may therefore be specified as B lines per square centimetre.
When the magnetizing current is twice reversed, so as to complete a cycle, the sum of the two deflections, multiplied by a factor depending upon the sectional area of the specimen and upon the constants of the apparatus, gives the hysteresis for a complete cycle in ergs per cubic centimetre.
Working with two different specimens, he found that the hysteresis loss in ergs per cubic centimetre (W) was fairly represented by o 00125B 1 6 and o o0101B 1 ' 6 respectively, the maximum induction ranging from about 300 to 3000.
After pointing out that, since the magnetization of the metal is the quantity really concerned, W is more appropriately expressed in terms of I, the magnetic moment per unit of volume, than of B, he suggests an experiment to determine whether the mechanical work required to effect the complete magnetic reversal i Phil.
Parshall quotes tests of six samples of iron, described as of good quality, which showed an average hysteresis loss of 3070 ergs per c.cm.
The standard induction in reference to determinations of hysteresis is generally taken as 2500, while the loss is expressed in watts per lb at a frequency of ioo double reversals, or cycles, per second.
In many experiments, however, different inductions and frequencies are employed, and the hysteresis-loss is often expressed as ergs per cubic centimetre per cycle and sometimes as horse-power per ton.
Since t horse-power= 746 watts, and r ton = 2 240 lb, the factor for reducing horse-power per ton to watts per lb is 746/2240, or just 1/3.
He made use of the expression F =Wg=27r12+HI, where W is the weight in grammes per square centimetre of sectional area, and g is the intensity of gravity which was taken as.
The greatest weight supported in the experiments was 14,600 grammes per square cm., and the corresponding induction 18, Soo units.
But when exceptionally strong fields are desired, the use of a coil is limited by the heating effect of the magnetizing current, the quantity of heat generated per unit of time in a coil of given dimensions increasing as the square of the magnetic field produced in its interior.
Du Bois's results, which, as given in his papers, show the relation of H to the magnetic moment per unit of mass, have been reduced by Ewing to the usual form, and are indicated in fig.
The force acting on the magnetism of one of the faces, and urging this face towards the other, will be less than B by 27r1, the part of the total force due to the first face itself; hence the force per unit of area with which the faces would press against each other if in contact is P = (B-27rI)I =27rT 2 +HI = (B 2 -H 2) =/81r.
Even under so " moderate " a load as 33 kilogrammes per square mm., the induced magnetization of a hard-drawn nickel wire in a field of 60 fell from 386 to 72 units, while the residual was reduced from about 280 to io.
The maximum susceptibility of one of his bars rose from 5.6 to 29 under a stress of 19.8 kilos per square mm.
Ewing's independent experiments showed that the magnetization curve for a cobalt rod under a load of 16.2 kilogrammes per square mm.
B =9000, at a frequency of loo per second, was only 0.254 watt per pound, as compared with 0.382 for the Swedish iron.
Its hysteresis-loss for B =9000 was o 236 per pound.
There was considerable hysteresis, the energy-loss per cycle being fairly represented by W =0.000549513 2 ' 238.
Annexed are values of Io 6 K for the different salts examined, w being the weight of the salt per c.c. of the solution.
In one case the hysteresis loss per cubic centimetre per cycle was 16,100 ergs for B =1 5,900, and only 1200 ergs for B = 20,200, the highest induction obtained in the experiment; possibly it would have vanished before B had reached 21,000.2 These experiments prove that actual friction must be almost entirely absent, and, as Baily remarks, the agreement of the results with the previously suggested deduction affords a strong verification of Ewing's form of the molecular theory.
In 1912 in the corresponding area there were 98 secondary schools with 22,600 pupils, one per 26,000 inhabitants (in Germany one per 54,000).

In 1900 the birth-rate was 26.90 per thousand, 7.8% of the births being illegitimate; the deathrate was 19.40 per thousand, and the marriage-rate 10 per thousand.
The circumstances of his appointment and the erroneous belief that he was receiving a pension of f 4 000 per annum for his few days' court work brought Campbell much unmerited obloquy.'
It contains manufactories of chemicals, machinery, starch, white lead and various other articles, but is chiefly noted for its extensive salt springs and works, which produce about 75,000 tons of salt per annum.

Population.-Hungary had in 1900 a population of 19,254,559, equivalent to 153.7 inhabitants per square mile.
In this respect, however, matters are improving, the death-rate sinking from 33.1 per thousand in1881-1885to 28.1 per thousand in 1896-1900.
These armaments, which cost Matthias 1,000,000 florins per annum, equivalent to 200,00O, did not include the auxiliary troops of the hospodars of Walachia and Moldavia, or the feudal levies of the barons and prelates.
The force operative upon the positive half is parallel to OZ, and of amount per unit of area equal to - b 2 D = b 2 kD cos nt; and to this force acting over the whole of the plane the actual motion on the positive side may be conceived to be due.
Like Fe 2 0 3, the yellow oxide lost 48 parts of oxygen per Ur203 (= 864 parts) as water, while Ur 2 = 816 parts of metal remained.
The population of the Transvaal, on the 17th of April 1904, when the first complete census of the country was taken, was 1,269,951 (including 8215 British soldiers in garrison),1 or 11.342 persons per sq.
It is grown at elevations of 1600 to 3000 ft., and the yield is reported to be a to 2 lb per tree, which is much less than the yield in Sao Paulo, Brazil.
The tree has an average height of 12-13 ft., begins bearing five years after planting, requires little attention beyond occasional irrigation, bears two crops a year (June and December), and produces well until it is forty years of age - the yield being from 490 to 600 lb per acre of 100 trees.
In 1903 the rate was fixed at R.12 per maund, against R.2 for the rest of India.
In a series of letters, De sedibus et causis morborum per anatomen indagatis, published when he was in his eightieth year, he describes the appearances met with at the post mortem examination as well as the symptoms during life in a number of cases of various diseases.

The subdrift system is somewhat cheaper than the top-slice system, the output per man being greater.
With an efficient engine the cost per gallon of water is often less than for pumping.
The speed is slow - from 4 to ro strokes per minute - but the larger sizes, up to 24 in.
This resistance is equal to the square of the velocity of the current in feet per minute, Air.
A certain pressure of air is required to maintain circulation against the resistance, and for a given volume per minute the smaller and more irregular the mine openings the greater must be the pressure.
Assuming, for example, the life of the mine at ten years as before, and taking the interest to be earned by the amortization fund at 3%, and that on the investment at io%, we shall find that the annual income should amount to 18.7% per year.
The density of population per square mile is 44 as compared with 167 for the whole of India and S52 for the Bengal Delta.
Within this area the petty chiefs have appointment orders, the people are disarmed, and the rate of tribute per household is fixed in each case.
Processes of annealing, or very gradual cooling, are intended to relieve these strains, but such processes are only completely effective when the cooling, particularly through those ranges of temperature where the glass is just losing the last traces of plasticity, is extremely gradual, a rate measured in hours per degree Centigrade being required.
Hence 1000Æ is the elongation in millimetres per metre length per kilo.
The pressure at any point cf a plane in the interior of a fluid is the intensity of the normal thrust estimated per unit area of the plane.
Hence the space variation of the pressure in any direction, or the pressure-gradient, is the resolved force per unit volume in that direction.
I n a straight uniform current of fluid of density p, flowing with velocity q, the flow in units of mass per second across a plane area A, placed in the current with the normal of the plane making an angle 0 with the velocity, is oAq cos 0, the product of the density p, the area A, and q cos 0 the component velocity normal to the plane.
As a rule these equations are established immediately by determining the component acceleration of the fluid particle which is passing through (x, y, z) at the instant t of time considered, and saying that the reversed acceleration or kinetic reaction, combined with the impressed force per unit of mass and pressure-gradient, will according to d'Alembert's principle form a system in equilibrium.
After the new centre was built, a society called the Societa per la difesa di Firenze antica was formed by many prominent citizens to safeguard the ancient buildings and prevent them from destruction, and a spirit of intelligent conservatism seems now to prevail in this connexion.
The canes in each case are assumed to contain 88% of juice and 12% of fibre, and the extraction by milling to be 75% of the weight of canes - the evaporative power of the factory being equal to 622 tons per 24 hours.
The factory expenses are taken at £30,000 per annum, or £3 per ton on a crop of 10,000 tons (the sugar to cost £8 per ton all told at the factory) - equivalent to £300 per day for the loo working days of crop time.
In India at the present day there are thousands of small mills worked by hand, through which extraction the peasant cultivators pass their canes two or three at a time, squeezing them a little, and extracting per haps a fourth of their weight in juice, from which they make a substance resembling a dirty sweetmeat rather than sugar.
Here the tropical heat is tempered by constant trade winds, there is perfect immunity from hurricanes, the soil is peculiarly suited for cane-growing, and by the use of specially-prepared fertilizers and an ample supply of water at command for irrigation the land yields from 50 to 90 tons of canes per acre, from which from 12 to 14% of sugar is produced.
To secure this marvellous return, with an annual rainfall of 26 in., as much as 52,000,000 gallons of water are pumped per 24 hours from artesian wells on one estate alone.
By the adoption of this system in one large plantation in the West Indies, crushing upwards of 1200 tons of canes per day, the labour of sixty-four hands was dispensed with, and was thus made available for employment in the fields.
In the best days of the so-called Jamaica Trains in Demerara, three-quarters of a ton of coal in addition to the megass was burned per ton of sugar made, and with this for many years planters were content, because they pointed to the fact that in the central factories, then working in Martinique and Guadeloupe, with charcoal filters and triple-effect evaporation, 750 kilos of coal in addition to the megass were consumed to make woo kilos of sugar.
But this competition among inventors, whatever the incentive, has not been without benefit, because to-day, by means of very simple improvements in details, such as the addition of circulators and increased area of connexions, what may be taken to be the standard type of multiple-effect evaporator (that is to say, vertical vacuum pans fitted with vertical heating tubes, through which passes the liquor to be treated, and outside of which the steam or vapour circulates) evaporates nearly double the quantity of water per square foot of heating surface per hour which was evaporated by apparatus in use so recently as 1885 - and this without any increase in the steam pressure.
That evaporation in vacuo, in a multiple-effect evaporator, is advantageous by reason of the increased amount of sugar obtained from a given quantity of juice, and by reason of economy of fuel, there is no doubt, but whether such an apparatus should be of double, triple, quadruple or quintuple effect will depend very much on the amount of juice to be treated per day, and the cost of fuel.
The average weight per acre was over 252 tons, and the mean percentage of pure sugar in the juice exceeded Isl.
The weight per acre, the saccharine contents of the juice, and the quotient of purity compared favourably with the best results obtained in Germany or France, and with those achieved by the Suffolk farmers, who between 1868 and 1872 supplied Mr Duncan's beetroot sugar factory at Lavenham; for the weight of their roots rarely reached 15 tons per acre, and the percentage of sugar in the juice appears to have varied between 10 and 12.
These cakes, sold as food for cattle, fetch as much as £4 per ton in Rumania, where four or five beetroot factories are now at work.
A process for purifying and decolorizing the juice expressed from beetroots by the addition of a small quantity of manganate of lime (20 to 50 grammes per hectolitre of juice), under the influence of an electric current, was worked with considerable success in a sugar factory in the department of Seine-et-Marne in the year 1900-1901.
The total saving effected is stated to be equivalent to 3 francs per ton of beetroot worked up. This system is also being tried on a small scale with sugar-cane juice in the West Indies.
By this arrangement the work of a refinery can be carried on with about one-half the cisterns otherwise required, because, although it does not reduce the number of bags required per day for a given amount of work, it enables the refiner to use one cistern twice a day with fresh bags, instead of only once as heretofore.
When, in April 1908, Mr Asquith became premier, and Mr Lloyd George chancellor of the exchequer, the sugar convention The world's trade in cane and beet sugar in tons avoirdupois at decennial periods from 1840 to 1870, inclusive, and yearly from 1871 to 1901 inclusive, with the percentage of beet sugar and the average price per cwt.
Quantities of raw and refined cane and beet sugar in tons avoirdupois imported into the United Kingdom in 1870 and in 1875, and yearly from 1880 to 1901 inclusive, with the consumption per head of the population in lb and the price per cwt.
It is calculated that in the NorthWest Provinces of India 5 per cent.
Quicklime is best applied, perhaps, in spring at the rate of one ton per acre every six or eight years, or in larger doses-4 to 8 tons - every 15 to 20 years.
In some cases as little as 40 loads per acre have been used with benefit, in others 180 loads have not been too much.
Great care is necessary to prevent the heaps from becoming too hot, in which case the clay becomes baked into hard lumps of brick-like material which cannot be broken up. With careful management, however, the clay dries and bakes, becoming slowly converted into lumps which readily crumble into a fine powder, in which state it is spread over and worked into the land at the rate of 40 loads per acre.
Careful examination of a large number of individuals of one variety growing under similar conditions reveals differences in such characters as number of leaves per plant, the size and shape of the leaves, tendency to form suckers, time of maturing and resistance to disease.

The distillation process in former times, especially in England, used to be carried out "per descensum."
The charge of the retorts consists of a mixture of 1100 lb of roasted calamine and 550 lb of dry powdered coal per furnace.
This dust may amount to Io per cent.
When hydraulic pressure to the amount of 2000 to 3000 lb per square inch is applied, the saving is unquestioned, since less time is required to dry the pressed retort, its life in the furnaces is longer, its absorption of zinc is less, and the loss of zinc by passage through its walls in the form of vapour is reduced.
The current efficiency was about 83 per cent.
It was found in practice (in 1889) that the expenditure of energy per pound of reduced aluminium was about 23 H.P.-hours, a number considerably in excess of that required at the present time for the production of pure aluminium by the electrolytic process described in the article Aluminium.
The civil list paid to the Bey of Tunis amounts to £36,000 per annum, and the endowment of the princes and princesses of the beylical family to £31,200 a year more.
Newcomb found an excess of motions in the perihelion of Mars amounting to about 5" per century.
Owing to the export tax on rubber (8 cents per kilogram on jebe and 5 cents on caucho) it is probable that the official statistics do not cover the total production, which was returned as 2539 metric tons in 1905, valued at £913,989.
The number of mining claims (pertenencias) registered in 1907 was 12,858, according to official returns, each subject to a tax of 30 soles, or £3, per annum, the payment of which secures complete ownership of the property.
Hoffmann the earliest mention of destillatio per descensum occurs in the writings of Aetius, a Greek physician who flourished at about the end of the 5th century.
The average, however, for the whole of the city is 126 per acre, or 80,640 per sq.
The annual death-rate per Imo for the whole population in 1902 was 21.70.
The light dues were reduced in 1898 from 22 cents to 1 cent per ton.
The hygienic improvement effected by these changes, and by a new and excellent water supply, is shown by the mortality averages-40 4 per thousand in 1871-1875,30.4 per thousand in 1881-1885, and 20.5 per thousand in 1903-1904.
Tallow candles as a substitute for whale-oil had been introduced, and the British market was closed by a duty of £r8 a ton on oil; a bounty offered by the Massachusetts legislature (£5 on white and £ 3 on yellow or brown spermaceti, and £2 on whale-oil per ton) was of slight assistance.
He collected the works of several French writers who as contemporaries described the crusades, and published them under the title Gesta Dei per Francos (Hanover, 1611).
Reichenhall possesses several copious saline springs, producing about 850o tons of salt per annum.
Cicero states that from the earliest period down to the pontificate of Publius Mucius Scaevola (c. 131 B.C.), it was usual for the pontifex maximus to record on a white tablet (album), which was exhibited in an open place at his house, so that the people might read it, first, the name of the consuls and other magistrates, and then the noteworthy events that had occurred during the year (per singulos dies, as Servius says).
As a consequence the public health has improved, the highest death-rate in the years 1901-1907 being 29.6 per 1000.
In 1900 Rhode Island ranked 17th among the states in the value of its manufactured products, but led all of the states in the value per capita ($430).
An irrigation canal, deriving water from the Sega, furnishes 112 cubic metres per second to the fields of the upper Veronese district.
Massimo to the suburb of Tombetta, furnishes 26 cubic metres of water per second, and generates 4000 horse-power.
The cutting of this canal led to the construction of an aqueduct for drinking water, which, besides supplying the city, furnishes an ice factory with enough water to make 200 quintals of ice per day.
A comparison of the force habitually developed by the wind in various parts of the islands shows that at Suttsu in Yezo the average strength is 9 metres per second, while Izuhara in the island Tsu-shima, Kumamoto in KiOshi and Gifu in the east centre of the main island stand at the bottom of the list with an average wind velocity of only 2 metres.
The ratio of marriages is approximately 8.46 per thousand units of the population, and the ratio of divorces is 1.36 per thousand.
Thus the expenditure by the state averaged 10,884 per mile, and that by private companies, 763 I.
Eight hydraulic hoists, of the most up-to-date pattern, are capable of shipping 5,600 tons of coal per hour.
The population of Styria in 1900 was 1,356,058, which is equivalent to 156 inhabitants per square mile.
A 10-12% solution of sodium chloride is caused to flow upwards through the apparatus and to overflow into troughs, by which it is conveyed (if necessary through a cooling apparatus) back to the circulating pump. Such a plant has been reported as giving 0.229 gallon of a liquor containing I% of available chlorine per kilowatt hour, or 0.171 gallon per e.h.p. hour.

Yarnold's process, using corrugated glass plates coated on one side with gold or other metal leaf, is stated to have yielded as much as 2700 grains per e.h.p. hour.
Aluminium, when alloyed with a few per cent of magnesium, gains greatly in rigidity while remaining very light; this alloy, under the name of magnalium, is coming into use for small articles in which lightness and rigidity have to be combined.
Sixty per cent of the present output of timber being needed for internal consumption, about 200,000 festmetres are available annually for export.
The quantity of alcohol present in an aqueous solution is determined by a comparison of its specific gravity with standard tables, or directly by the use of an alcoholometer, which is a hydrometer graduated so as to read per cents by weight (degrees according to Richter) or volume per cents (degrees according to Tralles).
In the United Kingdom the excise duty is eleven shillings per proof gallon of alcohol, while the customs duty is eleven shillings and 5' g fivepence; the magnitude of these imposts may be more readily understood when one remembers that the proof gallon costs only about sevenpence to manufacture.
It must be noted, however, that potential is a mere mathematical concept, and has no objective existence like difference of level, nor is it capable per se of producing physical changes in bodies, such as those which are brought about by rise of temperature, apart from any question of difference of temperature.
By the surface density of electrification on a conductor is meant the charge per unit of area, or the number of tubes of electric force which spring from unit area of its surface.
If a condenser of capacity C is charged to potential V, and discharged n times per second through a galvanometer, this series of intermittent discharges is equivalent to a current nCV.
From the speed of this motor the number of commutations per second can be determined.
Let a very small sphere be described round the source, and let the strength of the source be defined as the total flow per second through the surface of this small sphere.
Then if we have any number of sources enclosed by any surface, the total flow per second through this surface is equal to the total strengths of all the sources.
Suppose that the dielectric has a constant K, then we must multiply both sides by K and the expression for the energy per unit of volume of the field is equivalent to z DE where D is the displacement or polarization in the dielectric.
The area ABCD, representing the work, W, per cycle, is the difference (H' - H") of the quantities of heat absorbed and rejected at the temperatures 0 and 0".
He therefore employed the corresponding expression for a cycle of infinitesimal range dt at the temperature t in which the work dW obtainable from a quantity of heat H would be represented by the equation dW =HF'(t)dt, where F'(t) is the derived function of F(t), or dF(t)/dt, and represents the work obtainable per unit of heat per degree fall of temperature at a temperature t.
If two diatomic molecules, having each 5 degrees of freedom, combine to form a molecule with 6 degrees of freedom, we should have n = 2, or the energy lost would be 2pc per unit mass.
The total entropy of the system is found by multiplying the entropy per unit mass of the substance in each state by the mass existing in that state, and adding the products so obtained.
The famous description of the crusades, gesta Dei per Francos, was evidently to Villehardouin a plain matter-of-fact description, and it no more occurred to him to doubt the divine favour being extended to the expeditions against Alexius or Theodore than to doubt that it was shown to expeditions against Saracens and Turks.
On the other hand, the output of California, which was producing over £3,000,000 per annum in 1876, has fallen off, the average annual output from 1876 to 1900 being £2,800,000; in 1905 the yield was £3,839,000.
There has been no increase, and, indeed, no large fluctuation until quite recently in the output of New Zealand, which averaged £1,054,000 per annum from 1876 to 1898, but the production of the two years 190oand 1905 rose to £1,425,459 and £2,070,407 respectively.
The gold carries, on an average, £2 per ton, and is worked by ordinary methods of goldmining, stamp-milling and cyaniding.
The gold production of Russia has been remarkably constant, averaging £4,899,262 per annum; the gold is derived chiefly from placer workings in Siberia.
Under the most advantageous conditions the loss of gold may be estimated at 15 or 20%, the amount recovered representing a value of about two shillings per ton of gravel treated.
The water necessary to the process is pumped from the river; as much as 2000 gallons per minute is used on the larger dredges.
The height of lift may be between 4 and 18 in., and the number of blows from 30 to over loo per minute.
The total cost per ton of ore treated is about 6s., of which the cyaniding costs from 2S.
In the Transvaal the operation occupies 32 to 4 days for fine sands, and up to 14 days for coarse sands; the quantity of cyanide per ton of tailings varies from 0.26 to 0.28 lb, for electrolytic precipitation, and o 5 lb for zinc precipitation.
In the process employed at the Worcester Works in the Transvaal, the liquors, containing about 150 grains of gold per ton and from 0.08 to o 01% of cyanide, are treated in rectangular vats in which is placed a series of iron and leaden plates at intervals of 1 in.
When the secret treaty with France became known, thus confirming Sacheverell's insight, the latter called for the disbandment of the forces and advocated the refusal of further supplies for military purposes; and in June 1678 he resolutely opposed Lord Danby's proposal to grant £300,000 per annum to Charles II.
The salary of the secretary for foreign affairs is £s000 per annum, that of the permanent under-secretary £2000, the parliamentary under-secretary and the first assistant under-secretary, £150o,.
From 1830 to 1840 it steadily increased, but never reached 100,000 per annum.
Its, effect is shown by comparing the number of emigrants with the excess of births over deaths per moo of the population.
For instance, in 1891 the emigration from the provinces of West Prussia and Posen was extraordinarily heavy10.9 and Io 4 per mille respectively-but the excess of births over deaths was 19.6 per mille.
In the United States, for instance, it was shown in 1890 that more than 21.5 per cent.
But his negotiations yielded no definite result; and every other means of obtaining redress and security proving unsuccessful, the Assam Dwars were wrested from the Bhutias, and the British government consented to pay to Bhutan a sum of £l000 per annum as compensation for the resumption of their tenure, during the good behaviour of the Bhutias.
In 1906 the birth-rate was 40.68 per thousand, and the excess of births over deaths 2637.
The average cost per pupil in these schools was 35 s.
The average cost per student in the lyceum was 8, os.
Although Macao is de facto a colonial possession of Portugal, the Chinese government persistently refused to recognize the claim of the Portuguese to territorial rights, alleging that they were merely lessees or tenants at will, and until 1849 the Portuguese paid to the Chinese an annual rent of X71 per annum.
In 1661 he was created Lord Newark, and received a pension of £50o per annum.
From what remains of Machiavelli's official letters, and from his tract upon the Modo the tenne it duca Valentino per ammazzar Vitellozzo Vitelli, we are able to appreciate the actual relations which existed between the two men, and the growth in Machiavelli's mind of a political ideal based upon his study of the duke's character.
Besides homagium ligeum, there was a kind of homage which imposed no feudal duty; this was homagium per paragium, such as the dukes of Normandy rendered to the kings of France, and as the dukes of Normandy received from the dukes of Brittany.
Seven-tenths of this was improved land, and the expenditure per farm for fertilizers, greater in 1890 than the average of the Atlantic states, approximated $55 per farm in 1900.
In 1899 Delaware spent more per acre for fertilizers than any of the other states except New Jersey, Rhode Island and Maryland.
His surname is given by himself as "Serveto " in his early works, " per Michaelem Serueto, alias Reues."
But Gunkel's explanation is an attempt to account for one ignotum per ignotius; for hitherto no trace of the myth of the sun-god's birth and persecution and the flight into the wilderness has been found in Babylonian mythology.
Sonnstadt 2 detected gold by means of a colour test and roughly estimated the amount as i grain per ton of sea-water, and on this estimate all the projects for extracting gold from sea-water have been based.
According to Knudsen the salinity is given in weight per thousand parts by the expression S = o 030+ I.
According to Thoulet and Chevallier the specific heat diminishes as salinity increases, so that for io per mille salinity it is o 968, for 35 per mille it is only o 932, that of pure water being taken as unity.
The thermal conductivity also diminishes as salinity increases, the conductivity for heat of sea-water of 35 per mille salinity being 4.2% less than that of pure water.
The water from the greatest depths of the Black Sea, I160 fathoms, contains 6 cc. of sulphuretted hydrogen per litre.
The alkalinity of North Atlantic water of 35 per mille salinity is 26.86 cc. per litre, corresponding to a total amount of carbonic acid of 49 07 cc. According to the researches of August Krogh,' the alkalinity is greatly increased by the admixture of land water.
Ruppin's analysis of Baltic water, which has an alkalinity of 16 to 18 instead of the 5 or 6 which would be the amount proportional to the salinity, while the water of the Vistula and the Elbe with a salinity of o 1 per mille has an alkalinity of 28 or more.
The North Atlantic maximum is the highest with water of 37.9 per mille salinity; the maximum in the South Atlantic is 37.6; in the North Indian Ocean, 36.7; the South Indian Ocean, 36.4; the South Pacific, 36.9; and the North Pacific has the lowest maximum of all, only 35'9.
The saltest include the eastern Mediterranean with 39.5 per mille, the Red Sea with 41 to 43 per mille in the Gulf of Suez, and the Persian Gulf with 38.
The fresher enclosed seas include the Malay and the East Asiatic fringing seas with 30 to 34.5 per mille, the Gulf of St Lawrence with 30 to 31, the North Sea with 35 north of the Dogger Bank diminishing to 32 further south, and the Baltic, which freshens rapidly from between 25 to 31 in the Skagerrak to 7 or 8 eastward of Bornholm and to practically fresh water at the heads of the Gulfs of Bothnia and Finland.
The Arctic Sea presents a great contrast between the salinity of the surface of the ice-free Norwegian Sea with 35 to 35.4 and that of the Central Polar Basin, which is dominated by river water and melted ice, and has a salinity less than 25 per mille in most parts.
The average salinity of the whole surface of the oceans may be taken as 34.5 per mille.
In the North Atlantic a strong submarine current flowing outward from the Mediterranean leaves the Strait of Gibraltar with a salinity of 38 per mille, and can be traced as far as Madeira and the Bay of Biscay in depths of from 600 to 2800 fathoms, still with a salinity of 35.6 per mille, whereas off the Azores at equal depths the salinity is from 0.5 to 0.7 per mille less.
Our knowledge of the Pacific in this respect is still very imperfect, but it appears to be less salt than the other oceans at depths below 800 fathoms, as on the surface, the salinity at considerable depths being 34.6 to 34.7 in the Western part of the ocean, and about 34.4 to 34.5 in the eastern, so that, although the data are by no means satisfactory, it is impossible to assign a mass-salinity of more than 34.7 per mille for the whole body of Pacific water.
In Nassau and Bavaria woody structure is very common, and it is [[Table I]].-Elementary Composition of Coal (the figures denote the amounts per cent).
For the last thirty years the average increase in the output has been 22% per annum, and that in the exports (including bunkers) 42% per annum.
Denayrouze by which the air, contained in cylinders at a pressure of 300 to 350 lb per sq.
In the United Kingdom the drawing of coal is generally confined to the day shift of eight hours, with an output of from 100 to 150 tons per hour, according to the depth, capacity of coal tubs, and facilities for landing and changing tubs.
Modern screening and washing plants, especially when the small coal forms a considerable proportion of the output, are large and costly, requiring machinery of a capacity of ioo to 150 tons per hour, which absorbs 350 to 400 H.P. In this, as in many other cases, electric motors supplied from a central station are now preferred to separate steam-engines.
The yield per man on the working faces was 4.5 tons, and for the whole of the working force underground, o 846 tons, which is not less than that realized in shallower mines.
Pure crystalline calcium carbide yields 5.8 cubic feet of acetylene per pound at ordinary temperatures, but the carbide as sold commercially, being a mixture of the pure crystalline material with the crust which in the electric furnace surrounds the ingot, yields at the best 5 cubic feet of gas per pound under proper conditions of generation.
A statement of the amount made per kilowatt hour may be misleading, since a certain amount of loss is of necessity entailed during this process.
When acetylene is burnt from a 000 union jet burner, at all ordinary pressures a smoky flame is obtained, but on the pressure being increased to 4 inches a magnificent flame results, free from smoke, and developing an illuminating value of 240 candles per 5 cubic feet of gas consumed.
On his return he was contemplating emigration to New England, when in June 1773 Lord North, on the recommendation of Lord Barrington, appointed him a member of the newly constituted supreme council of Bengal at a salary of io,000 per annum.
The power of a motor is measured by the rate at which it works, and this is expressed by Tw =T 60N in foot-pounds per second.
The rate at which the motor is transmitting work is then 550 H.P., where n is the revolutions per second of the armature.

We pass from one number to the next per saltum.
Let a mixture of gases contain per unit volume v molecules of the first kind, v' of the second kind, and so on.
The number of molecules of the first kind of gas, whose components of velocity lie within the ranges between u and u+du, v and v+dv, w and w+dw, will, by formula (5), be v?l (h 3 m 3 /7 3)e hm (u2+v2+w2)dudvdw (9) per unit volume.

For cities of above 8000 inhabitants (for which alone comparative statistics are annually available), in 1902-1903 the ratio of average attendance to school enrolment, the average number of days' attendance of each pupil enrolled, and the value of school property per capita of pupils in average attendance were higher than in any other state; the average length of the school term was slightly exceeded in eight states; and the total cost of the schools per capita of pupils in average attendance ($39.05) was exceeded in six other states.
In 1900 the average period of schooling per inhabitant for the United States was 4.3 years, for Massachusetts 7 years.
The whole number of paupers, besides vagrants, in 1908 was 23.02 per moo of state population, and the cost of relief ($5,104,2J5) was $1.699 for each inhabitant of the state.
This suspension is then run through a conical mill in order td remove all grit, the cones of the mill fitting so tightly that water cannot pass through unless the mill is running; the speed of the mill when working is about 3000 revolutions per minute.
The annual deathrate per 1000 was 54 per 1000 for the Federal District in 1901, 50 ill 1902, 48 in 1903, 46 in 1904, and 56 in 1905; the increase for the last-mentioned year being due to an epidemic of typhus fever.
All these sources are estimated to yield about 220 to 230 litres per head.
Per contra, much that was only " implicit " in the deposit of faith has become " explicit " in dogma.
But whatever merits they had as clarifiers of turbid water, the advent of bacteriology, and the recognition of the fact that the bacteria of certain diseases may be water-borne, introduced a new criterion of effectiveness, and it was perceived that the removal of solid particles, or even of organic impurities (which were realized to be important not so much because they are dangerous to health per se as because their presence affords grounds for suspecting that the water in which they occur has been exposed to circumstances permitting contamination with infective disease), was not sufficient; the filter must also prevent the passage of pathogenic organisms, and so render the water sterile bacteriologically.
The following table gives the total and the per capita cost of each enumeration.
For the sake of comparison it may be stated that the per capita cost of the English census of 1901 was 2.24 cents, or little more than one-tenth that of the American census.
One ounce of standard silver, which contains 925 parts of silver and 75 of copper per 1000, is converted into 5s.
In the sovereign it is 0.2 grain or about 1.62 per moo.
The remedies for weight on foreign coins are in general greater than those allowed in the British Empire, averaging 2 per moo for gold coins.
In England the remedy for fineness is 2 per moo on gold coins and 4 per moo on silver coins above and below the legal standard.
Thus gold coins would be within the limits if they contained between 914.6 and 918.6 parts of gold per 1000.
The cutting machines at the Mint work at 160 revolutions per minute, so that each of the eleven machines would be capable of cutting 19,200 blanks in an hour if it could be fed continuously.
About 720 blanks are passed through this machine per minute.
The amount of copper removed from silver blanks containing 900 to 925 parts of silver per moo is from o 6 to I o per 1000.
The at the Mint strike from 90 to 125 coins per minute, most of them working at the rate of Iio coins per minute.
Algol, in fact, travels at the rate of 26.3 miles a second round the centre of gravity of the system which it forms with an invisible companion, while the two together approach the sun with an unvarying speed of 2.3 miles per second.
A fair crop of barley yields about 36 bushels, (56 lb to the bushel) per acre, but under the best conditions 40 and 50 bushels may be obtained.
The continental portion, although less mixed than that of the peninsula, consists of Great and Little Russians, who constitute 83 per cent.
The healthiness of the New Zealand climate in all parts is attested by the death-rate, which, varying (1896-1906) from 9 to 10.50 per 1000, is the lightest in the world.
Let E be the bulk modulus of elasticity, defined as increase of pressure = decrease of volume per unit volume where the pressure increase is so small that this ratio is constant, w the small increase of pressure, and - (dy/dx) the volume decrease, then E=e/(- dy/dx) or w Æ= - dy/dx (I) This gives the relation between pressure excess and displacement.
The pitch of a sound, the note which we assign to it, depends on the number of waves received by the ear per second.
This is generally equal to the number of waves issuing from the source per second, and therefore equal to its frequency of vibration.
