But every genuine attempt to overcome its difficulties brings us into closer touch with the period we are examining; and though we may not be able to throw our conclusions into the form of large generalizations, we shall get to know something of the operation of the forces which determined the economic future of England; understand more clearly than our forefathers did, for we have more information than they could command, and a fuller appreciation of the issues, the broad features of English development, and be in a position to judge fairly well of the measures they adopted in their time.
If we go to Mill to discover what it is, we find that " it is not pretended that the law of diminishing return was operative from the beginning of society; and though some political economists may have believed it to come into operation earlier than it does, it begins quite early enough to support the conclusions they founded on it."
" It comes into operation at a certain and not very advanced stage in the progress of agriculture."
It is therefore extraordinarily difficult at present to know what happens, or rather what would happen if it were not prevented, when a country reaches " the stage of diminishing returns "; what precisely it is which comes into operation, for obviously the diminishing returns are the results, not the cause; or how commodities " obey " a law which is always " suspended."

The charge was distilled almost to dryness, though the operation was not carried far enough to cause the residue to " coke."
The operation was, however, completely revolutionized in the United States by the introduction of the " cracking process," and by the division of the distillation into two parts, one consisting in the removal of the more volatile constituents of the oil, and the other in the distillation (which is usually conducted in separate stills) of the residues from the first distillation, for the production of lubricating oils and paraffin.

An entirely new project was an international survey of the Mediterranean and adjacent seas, from the fishery and oceanographical standpoints, by France, Italy, Spain and Portugal, but in 1921 no definite programme had been put in operation.
On the other hand, we may imagine the processes due to the electrical transfer to be reversed by an osmotic operation.
Solvent may be supposed to be squeezed out from the solution which has become more dilute through a semi-permeable wall, and through another such wall allowed to mix with the solution which in the electrical operation had become more concentrated.
Again, we may calculate the osmotic work done, and, if the whole cycle of operations be supposed to occur at the same temperature, the osmotic work must be equal and opposite to the electrical work of the first operation.
Such measures, which are now in operation in the French Sudan, the Congo and in German W.
Before commencing the mastication it is generally necessary to warm the apparatus by means of steam; but as the operation proceeds the heat produced requires to be moderated by streams of cold water flowing through channels provided for the purpose.
Rubber mixed in the usual way with about WA of sulphur is now softened by heat, forced into the mould, and retained there by pressure during the operation of curing, which is usually effected in an iron box heated over a gas burner to 140° C.

An important associated operation is a ?
Moreover, its operation upon any invariant form produces an invariant form.
It is essentially an operation performed upon the product of ï¿½two forms. If, then, we require the transvectants of the two forms f+Xf', 0+14', we take their product fc5+xf'95+,-ifct'+atif'cb', and the kth transvectant is simply obtained by operating upon each term separately, viz.

At this stage as a rule some rich slags of a former operation are added and a quantity of quicklime is incorporated, the chief object of which is to diminish the fluidity of the mass in the next stage, which consists in this, that, with closed air-holes, the heat is raised so as to cause the oxide and sulphate on the one hand and the sulphide on the other to reduce each other to metal.
As a preliminary to the melting process, the "browse" left in the preceding operation (half-fused and imperfectly reduced ore) is introduced with some peat and coal, and heated with the help of the blast.
While he also prevents interruption of the operation by means of water-jackets, he uses hot-blast, and produces, besides metallic lead, large volumes of lead fumes which are drawn off by fans through long cooling tubes, and then forced through suspended bags which filter off the dust, called "blue powder."
In the beginning of the operation enough argentiferous lead is charged to fill the cavity of the test.

If the operation has been skilfully performed the ring will have no poles and will not attract iron filings.
One of the fragments may again be broken, and again two bipolar magnets will be produced; and the operation may be repeated, at least in imagination, till we arrive at molecular magnitudes and can go no farther.
This operation, besides being very troublesome, was open to the objection that it was almost sure to produce a material but uncertain change in the physical constitution of the metal, so that, in fact, the results of experiments made before and after the treatment were not comparable.
Grassot has devised a galvanometer, or " fluxmeter," which greatly alleviates the tedious operation of taking ballistic readings.2 The instrument is of the d'Arsonval type; its coil turns in a strong uniform field, and is suspended in such a manner that torsion is practically negligible, the swings of the coil being limited by damping influences, chiefly electromagnetic. The index therefore remains almost stationary at the limit of its deflection, and the deflection is approximately the same whether the change of induction occurs suddenly or gradually.
If the operation is again reversed, the upward course will be nearly, but not exactly, of the form shown by the line d c a, fig.
units in the case illustrated in the figure), an operation which is performed by simply reversing, the direction of the maximum magnetizing current a few times.
An experiment by Ewing showed that by the operation of stretching an annealed iron wire beyond the limits of elasticity the permeability under a magnetizing force of about 3 units was reduced by as much as 75%.
The method, though tedious in operation, is very accurate, and is largely employed for determining the magnetic quality of bars intended to serve .as standards.
24 was converted into an almost perfectly straight line passing through the origin, and lying below the horizontal axis; while the permeability of the metal was greatly diminished by the operation.
After this operation had been repeated a few times the iron was found to have acquired a stable condition, and the curves corresponding to the two temperatures became perfectly definite.
Although specially exempted from the operation of the decree of October 1 793, imposing banishment on foreign residents, he took alarm at the fate of J.
An inland parcel post was in operation long before the overthrow of the monarchy, and a similar service with Portugal has been successfully maintained for a number of years, notwithstanding the difficulties interposed by customs regulations.
National and international money order systems are also in operation.
The Ypanema mine and ironworks, near Sorocaba, Sao Paulo, which belong to the national government, have been in operation since 1810, and small charcoal forges were in operation in colonial times and supplied the mines with a considerable part of the iron needed by them.
There were 155 of these factories in 1895, but in 1905 only 108 were in operation, with 715,000 spindles, and about 37, 00 o operatives.
The scheme came into operation in June 1898, and not only was a complete suspension of payments avoided but the financial situation was greatly improved.
The discontent arising among Brazilians from this cause was heightened by a decree assigning a heavy tax on the chief Brazilian custom houses, to be in operation for forty years, for the benefit of the Portuguese noblemen who had suffered during the war with France.
The native laws were first codified in 1878, in 1887 a board was appointed for their revision, and the new code came into operation in 1901.
Provision is made whereby a native can obtain relief from the operation of native law and be subject to the colonial law (Law No.
But these Indians by reindenturing might come under the operation of the repatriation proposal.
But in many cases the patient prefers that the abdomen should be opened for exploration for a possible operation than that he should hopelessly give himself over to the disease.
And sometimes the surgeon is enabled by operation to give great relief, though the removal of the growth itself is impracticable.
This operation is called gastrostomy and may be the means of giving many weeks of comfort to the unhappy patient - provided that its performance is not too long postponed.
In some early cases of pyloric cancer resection of the disease may be performed, the upper end of the intestine being afterwards joined to the middle of the stomach by a kind of short-circuiting operation.
This ingenious operation widens the track at the expense of an unimportant fraction of its length.
Loreta's operation for dilatation of the outlet of the stomach is now rarely performed.
It was replied that Hungary was outside the operation of the treaty of Westphalia, and that the Protestants had been condemned not ex odio religionis but crimine rebellions.
(ii.) The above operation is performed with i lb as the unit of counting, and the process would be the same with any other unit; e.g.
(vi.) Any compound operation not coming under the above descriptions is to have its meaning made clear by brackets, the use of a pair of brackets indicating that the expression between them is to be treated as a whole.
processes which consist in obtaining an answer to the question " Upon what has a given operation to be performed in order to produce a given result?"
or to the question " What operation of a given kind has to be performed on a given quantity or number in order to produce a given result?"
(iii.) Where the direct operation is evolution, for which there is no commutative law, the two inverse operations are different in kind.
In the same way, a statement as to the result of an inverse operation is really, by the definition of the operation, a statement as to the result of a direct operation.
In the present section, however, we return from the inverse operation to the direct; i.e.
This states that the result of the operation of multiplying 3/b by 4 is 12 lb.
(iii.) The general statement of the laws of operation of fractions is perhaps best deferred until we come to fractional numbers, when letters can be used to express the laws of multiplication and division of such numbers.
(c) The fundamental properties of subtraction and of division are that A - B +B = A and m X m of A = A, since in each case the second operation restores the original quantity with which we started.
This is sometimes treated as a debt of 5s.; an alternative method is to recognize that our zero is really arbitrary, and that in fact we shift it with every operation of addition or subtraction.
In algebraical transformations, however, such as (x-a)2 = x 2 - 2ax+a 2, the arithmetical rule of signs enables us to combine the sign-with a number and to treat the result as a whole, subject to its own laws of operation.
We see first that any operation with 4a-3b can be regarded as an operation with (+)4a+(-)3b, subject to the conditions (I) that the signs (+) and (-) obey the laws (+)=(+),(+)(-)=(-)(+)= (-), (-) (-)=(+), and (2) that, when processes of multiplication are completed, a quantity is to be added or subtracted according as it has the sign (+) or (-) prefixed.
Theoretically, no limit can be assigned to the number of possible algebras; the varieties actually known use, for the most part, the same signs of operation, and differ among themselves principally by their rules of multiplication.
Even when the formal evolution of the science was fairly complete, it was taken for granted that its symbols of quantity invariably stood for numbers, and that its symbols of operation were restricted to their ordinary arithmetical meanings.
The symbol e 0 behaves exactly like i in ordinary algebra; Hamilton writes I, i, j, k instead of eo, el, e2, es, and in this notation all the special rules of operation may he summed up by the equalities = - I.
But when an algebra is used with a particular interpretation, or even in the course of its formal development, it frequently happens that new symbols of operation are, so to speak, superposed upon the algebra, and are found to obey certain formal laws of combination of their own.
Finally, it brought the simplest living matter or formless protoplasm before the mental vision as the startingpoint whence, by the operation of necessary mechanical causes, the highest forms have been evolved, and it rendered unavoidable the conclusion that this earliest living material was itself evolved by gradual processes, the result also of the known and recognized laws of physics and chemistry, from material which we should call not living.
Thus mysticism was finally banished from the domain of biology, and zoology became one of the physical sciences - the science which seeks to arrange and discuss the phenqmena of animal life and form, as the outcome of the operation of the laws of physics and chemistry.
It is to be noted that, whilst the zoological system took the form of a genealogical tree, with main stem and numerous diverging branches, the actual form of that tree, its limitation to a certain number of branches corresponding to a limited number of divergences in structure, came to be regarded as the necessary consequence of the operation of the physico-chemical laws of the universe, and it was recognized that the ultimate explanation of that limitation is to be found only in the constitution of matter itself.
The most instructive classification of the " variations " exhibited by fully formed organisms consists in the separation in the first place of those which arise from antecedent congenital, innate, constitutional or germinal variations from those which arise merely from the operation of variation of the environment or the food-supply upon normally constituted individuals.
Since the limitation of the width of the central band in the image of a luminous line depends upon discrepancies of phase among the secondary waves, and since the discrepancy is greatest for the waves which come from the edges of the aperture, the question arises how far the operation of the central parts of the aperture is advantageous.
By the operation of the object-glass LL' all the rays issuing from A arrive in the same phase at B.
Throughout the operation of increasing the focal length, the resolving power of the instrument, which depends only upon the aperture, remains unchanged; and we thus arrive at the rather startling conclusion that a telescope of any degree of resolving power might be constructed without an object-glass, if only there were no limit to the admissible focal length.
He was again minister of the treasury from November 1903 to March 1905 in Giolitti's second administration, and for the third time from February to May 1906, under Sonnino's premiership. During the latter term of office he achieved the conversion of the Italian 5% debt (reduced to 4% by the tax) to 31% to be eventually lowered to 32%, an operation which other ministers had attempted without success; although the actual conversion was not completed until after the fall of the cabinet of which he formed part the merit is entirely his.
Rose Innes as chief justice, was put into operation; in 1902 this was followed by the establishment of a supreme court.
It is the subject of the operation of certain forces in virtue of which it undergoes internal changes, modifies external objects, and is modified by them; and 4.
This operation is no doubt intended to remove the oxygen diffused throughout the metal as oxide, part of it perhaps chemically by reduction of the oxide to metal, the rest by conveying the finely diffused oxide to the surface and causing it to unite there with the oxide scum.
The tinning of a copper basin is an easy operation.
The most important form of the operation is making tinned from ordinary sheet iron (making what is called "sheet tin").
The acid is then slowly run out by an opening in the bottom of the pan in which the operation is conducted, and water distributed carefully over its surface displaces it in the interstices of the cotton, which is finally subjected to a course of boiling and washing with water.
In December General Castro left upon a visit to Europe, nominally for a surgical operation.
The mineral resources include gold, silver, copper and petroleum, but no mines were in operation in 1906.
A successful operation for cataract restored his eyesight in June 1900, and notwithstanding his 81 years he resumed to some extent his former political activity.
As during this operation the II.
The Army of the North, which had reached Olmutz on the 10th of July, now received orders to move by road and rail towards Vienna, and this operation brought them right across the front of the II.
Ether is manufactured by the distillation of 5 parts of 90% alcohol with 9 parts of concentrated sulphuric acid at a temperature of 140°-145° C., a constant stream of alcohol being caused to flow into the mixture during the operation.
Or again, in the case of paired organs, if one be removed by operation, or destroyed by disease, the other at once undertakes to carry on the functions of both.
In the wasting of the thyroid gland in myxoedema, or when the gland is completely removed by operation, myxomatous areas are found in the subcutaneous tissue of the skin, nerve-sheaths, &c.
According to its doctrines the normal as well as diseased actions of the body were to be referred to the operation of the pneuma or universal soul.
While it was being mixed, holy writings were read to those engaged in the operation.
The bill was thrown out on this occasion, but was revived and passed in 1904, and on the 17th of June 1905 the service was put into operation.
In 1903 the Education (London) Act was passed in pursuance of the general system, put into operation by the Education Act (1902) of bringing education within the scope of municipal government.
The bills were killed by the action of the Registration Act for England and Wales, which came into operation July 1, 1837.
The amending acts, while not interfering with the operation of the principal act, authorize the creation of highway districts on a larger scale.
When the development of a mine has advanced sufficiently the operation of working or extracting the mineral begins.
In deep mines the pillars may furnish the bulk of the product, and the control of the fall of the roof, so as to permit the successful extraction of the mineral, demands a well-schemed plan of operation.
At mines with vertical shafts this is a simple operation.
At a few mines special man-cages are operated in separate compartments by their own engines for handling part of the men, and for tools, supplies, &c. For inclined shafts, where the mineral is hoisted in skips, the operation of raising and lowering men may not be so simple.
Tanks operated by the main hoisting engines, and of capacities up to 50o gallons or more, are applicable under several conditions: (1) When the shaft is deep, the quantity of water insufficient to keep a pump in regular operation, and the hoisting engine not constantly employed in raising mineral, the tank is worked at intervals, being attached temporarily to the hoisting rope in place of the cage.
Occasionally, at very gassy and dangerous collieries, two fans and driving engines are erected at the same air shaft, and in case of accident to the fan in operation the other can be started within a few minutes.
This is an expensive operation as it entails the cost of pumping the water out again and repairing the resulting damage.
3, but the operation partook merely of the nature of a reconnaissance, and for some time hostilities were confined to a blockade of the Ottoman coasts,' defensive steps in Egypt, and the seizure of the Shat el Arab and Basrah.
The conclusion arrived at on that occasion had, however, been that, whether the campaign were to take the form of a purely naval operation or whether the task were to be performed by an amphibious expeditionary force, the enterprise was bound to prove most difficult.
2 1915 for help to relieve the existing situation in Armenia, and an operation directed against the Dardanelles was judged to be the best means of complying with the request; but there were no large bodies of troops available that could be used for such a purpose.
This operation took place on March 18, and it proved unsuccessful.
De Robeck felt himself obliged to inform the Admiralty that the offensive against the Straits ought not to be continued as a purely naval operation of war.
A tactical operation of that character demanded most careful prior organization, and it called for a distribution of the attacking force amongst the available shipping based on purely tactical considerations.
As it turned out, the actual disembarkations at " S," " X " and " Y " were carried out without any very great difficulty; but the troops detailed for " W " beach only gained a footing after incurring very heavy losses and by a display of indomitable resolution, while at " V " the operation went very near to failing altogether.
Then on the 21st the French, who were on the right next to the Straits, pushed their line forward as the result of a wellplanned local offensive, and this achievement was followed up on the 28th by a successful operation on the part of the British on the extreme left, by which the line at that end was advanced to nearly abreast of Krithia.
The object of this second operation was twofold - it would indirectly assist the offensive against Sari Bair, it would also furnish the Allies who were planted down on the outer coast of the peninsula with a much more sheltered landing place and base than Anzac Cove.
The secret had been well kept, and a difficult operation of war was in its opening stages most successfully carried out.
But after a sanguinary contest the assailants met with repulse, and from that date onwards no serious offensive operation was attempted by the Allies in the Dardanelles campaign.
Foreseeing that the British Government must ultimately resign itself to a withdrawal of the Dardanelles army from its dangerous situation on the Gallipoli Peninsula, Monro had already, some days before the permission to evacuate reached him from home, given instructions that certain preparations were to be made towards facilitating that operation.
The naval authorities had been busy assembling and organizing the available small craft in anticipation of the operation that appeared to be imminent, and jetties damaged in the Nov.
The final night was provisionally fixed as that of the 18th - 19th, and thanks to favourable weather and to the efficiency of the arrangements, the very critical operation was carried out with triumphant success, just as had been laid down by programme ten days before.
That night the troops still left at Helles were reduced by one-third, and, on the next day breaking fine, it was decided to complete the operation on the following night as intended at the start.
In this process, however, the entire operations of splitting and flattening are retained, and although the mechanical process is said to be in successful commercial operation, it has not as yet made itself felt as a formidable rival to hand-made sheet-glass.
The mechanical operation is quite successful for thick sheets, but it is not as yet available for the thinner sheets required for the ordinary purposes of sheet-glass, since with these excessive breakage occurs, while the sheets generally show grooves or lines derived from small irregularities of the drawing orifice.
This operation, like all the subsequent steps in the polishing of the glass, is carried out by powerful machinery.
The works continued in operation until 1641.
A few of these letters deal with the glass trade, and in one a list is given of the glass-works then in operation.
His most important military operation, how ever, was when in 1346 he successfully held out in Beauvais.
The process originally suggested by Mansfield is generally followed, the success of the operation being principally conditioned by the efficiency of the dephlegmator, in which various improvements have been made.
He was responsible, especially, for the great operation known as the opening of the Grand Livre (August 2 4), which was designed to consolidate the public debt by cancelling the stock issued under various conditions prior to the Revolution, and issuing new stock of a uniform character, so that all fund-holders should hold stock of the revolutionary government and thus be interested in its stability.
Conversely, a combination of increased pressure and lowering of temperature will, if carried far enough, reduce a gas to a liquid, and afterwards to the solid state; and nearly every gaseous substance has now undergone this operation.
ih shows also a modern form of the hydraulic press, applied to the operation of covering an electric cable with a lead coating.
Consider, for instance, the operation of casting a hemispherical bell, in fig.
Finally, Charlemagne, who took a keen interest in the ancient documents, had the law emended, the operation consisting in eliminating the Malberg glosses, which were no longer intelligible, correcting the Latinity of the ancient:text, omitting a certain number of interpolated chapters, and adding others which had obtained general sanction.
The second operation is the coagulation of the albumen, and the separation of it with other impurities from the Maceration or Imbibition.
When a sufficient number are not available for a two hours' defecation, it is the practice in some factories to skim off the scums that rise to the top, and then boil up the juice for a few minutes and skim again, and, after repeating the operation once or twice, to run off the juice to separators or subsiders of any of the kinds previously described.
Evaporation of the Juice to Syrup. - The third operation is the concentration of the approximately pure, but thin and watery, juice to syrup point, by driving off a portion of the water in vapour through some system of heating and evaporation.
The claying system involved the expense of large curing houses and the employment of many hands, and forty days at least were required for completing the operation and making the sugar fit for the market, whereas with centrifugals sugar cooked to-day can go to market to-morrow, and the labour employed is reduced to a minimum.
When the new cell comes into operation and becomes the head of the battery, the first or tail cell is thrown out, and number two becomes the tail cell, and so the rounds are repeated; one cell is always being emptied and one filled or charged with slices and heated up, the latter becoming the head of the battery as soon as it is ready.
The whole operation of thus changing a filter occupies about ten minutes, and there is no need for anyone to enter the hot cistern to detach the bags, which are removed in the open air above the mud tank.
Similar tribunals were also in operation in the provinces.
In the operation of ploughing the furrow slice is separated from the soil below, and although in humid soils this layer may be left to settle by degrees, in semi-arid regions this loosened layer becomes.
The operation consists of paring off the tough sward to a depth of I to 2 in.
The operation is best carried out in spring and summer.
No operation brings old turf into cultivation so rapidly.
The best time for the operation appears to be late summer and autumn.
They were indeed expressly exempted from its general operation.
This operation requires experienced judgment to decide when it should be done; the number of leaves to be left varies with the variety and vigour of the plant, the nature of the soil, climate, seasons and particular use for which the crop'is intended.
When fermentation is completed the tobacco is graded, an operation carried out very carefully in the case of the better cigar tobaccos, and packed for export, cigar tobaccos in bales, and other kinds in hogsheads.
If the zinc is present as blende, this operation offers considerable difficulties, because in the roasting process the zinc sulphide passes in the first instance into sulphate, which demands a high temperature for its conversion into oxide.
The modern processes may be primarily divided into two groups according to the nature of the vessel in which the operation is effected.
The charging operation being completed, the temperature is raised, and as a consequence an evolution of carbon monoxide soon begins, and becomes visible by the gas bursting out into the characteristic blue flame.
Chemical control of the metal purchased is not nearly as common as it should be, and the refining of zinc is at best an imperfect operation.
This operation, performed in the garden by means of the spade, is carried on in the field on a larger scale by the plough,' which breaks the soil and by inverting the furrow-slice, exposes fresh surfaces to the disintegrating influence of air, rain and frost.
In operation the coulter makes a perpendicular cut separating the furrow-slice which is divided from the "sole" of the furrow Crested Furrow.
In animal physiology he set himself to trace out the operation of determinate chemical and physical laws in the maintenance of life and health.
Thus for instance when any feudal institution (be it Gothic, Norman, or Anglo-Saxon) eludes our deciphering faculty from the imperfect records of its use and operation, then we endeavour conjecturally to amend our knowledge by watching the circumstances in which that institution arose."
But whereas, from its construction, the Siemens furnace was intermittent in operation, necessitating stoppage of the current while the contents of the crucible were poured out, many of the newer forms are specially designed either to minimize the time required in effecting the withdrawal of one charge and the introduction of the next, or to ensure absolute continuity of action, raw material being constantly charged in at the top and the finished substance and by-products (slag, &c.) withdrawn either continuously or at intervals, as sufficient quantity shall have accumulated.
The current, either continuous or alternating, is then started, and continued for about 1 to 12 hours, until the operation is complete, the carbon rods being gradually withdrawn as the action proceeds.
The crude anthracene cake is purified by treatment with the higher pyridine bases, the operation being carried out in large steam-jacketed boilers.
being in operation in 1906.
In 1876 new mining laws were enacted which gave better titles to mining properties and better regulations for their operation, but the outbreak of the war with Chile at the end of the decade and the succeeding years of disorganization and partisan strife defeated their purpose.
The curacas sorrowfully watched the gradual extinction of their people by the operation of the mita, protesting from time to time against the exactions and cruelty of the Spaniards.
distillare, more correctly destillare, to drop or trickle down), an operation consisting in the conversion of a substance or mixture of substances into vapours which are afterwards condensed to the liquid form; it has for its object the separation or purification of substances by taking advantage of differences in volatility.
If the substance operated upon be practically pure to start with, or the product of distillation be nearly of constant composition, the operation is termed "purification by distillation" or "rectification"; the latter term is particularly used in the spirit industry.
If a complex mixture be operated upon, and a separation effected by collecting the distillates in several portions, the operation is termed "fractional distillation."
The vaporization of a substance below its normal boiling-point can also be effected by blowing in steam or some other vapour; this operation is termed "distillation with steam."
nitrogen, carbon dioxide, &c., which is led in at the distilling flask before the process is started, and a slow current maintained during the operation.
The success of the operation depends upon two factors: (I) that the heating be careful, slow and steady, and (2) that the column attached to the flask be efficient to sort out, as it were, the most volatile vapour.
With substances prone to discolorization, as, for example, certain amino compounds, the operation may be conducted in an atmosphere of carbon dioxide, or the water may be saturated with sulphuretted hydrogen.
Prior to 1830, little was known of the process other than that organic compounds generally yielded tarry and solid matters, but the discoveries of Liebig and Dumas (of acetone from acetates), of Mitscherlich (of benzene from benzoates) and of Persoz (of methane from acetates and lime) brought the operation into common laboratory practice.
For efficiency the operation must be conducted with small quantities; caking may be prevented by mixing the substance with sand or powdered pumice, or, better, with iron filings, which also renders the decomposition more regular by increasing the conductivity of the mass.
Sidney Young has suggested conducting the operation in a current of carbon dioxide which sweeps out the vapours as they are evolved, and also heating in a vapour bath, e.g.
In its more complete form a still has in addition the following fittings: - The dome is provided with openings to admit (I) the axis of the stirring gear (in some stills the stirring gear rotates on a horizontal axis which traverses the side and not the head of the still), (2) the inlet and outlet tubes of a closed steam coil, (3) a tube reaching to nearly the bottom of the still to carry live steam, (4) a tube to carry a thermometer, (5) one or more manholes for charging purposes, (6) sight-holes through which the operation can be watched, and (7) a safety valve.
The success of the operation chiefly depends upon the proper management of the cooler.
He attributed his father's pecuniary losses and his own to the operation of the corn laws.
Partly through restrictive local legislation and partly as a result of the operation of the Suffolk system of redemption in Boston, these institutions were always conservative.
The one process is a logical operation, the other a physical.
Great skill is shown in this operation, which achieves perhaps the finest facsimile reproduction of drawings ever known withotit the aid of photographic processes.
In color-printing, the colors, which are much the same as those in use in Europe, are mixed, with rice-paste as a medium, on the block for each operation, and the power of regulating the result given by this custom to an intelligent craftsman (who, again, is neither the artist nor the engraver) was productive in the best period of very beautiful and artistic effects, such as could never have been obtained by any mechanical device.
Several independent chisellings may be necessary before the lines of the (liaper emerge clearly, but throughout the whole operation no measurement of any kind is taken, the artist being guided entirely by his hand and eye.
Owing to the use of paper among the threads of the embroidery and sizing in the preparation of the stuff forming the ground, every operation of folding used to cause perceptible injury to a piece, so that after a few years it acquired a crumpled and dingy appearance.
The whole line is now in operation.
ways operation was impossible in such circumstances, and constant complaints were heard about delays in transit and undue expense.
Unfortunately he was attacked by cancer in the throat; he spent the winter of 1887-1888 at San Remo; in January 1888 the operation of tracheotomy had to be performed.
It arose from the fact that as early as May 1887 the German physicians recognized the presence of cancer in the throat, but Sir Morell Mackenzie, the English specialist who was also consulted, disputed the correctness of this diagnosis, and advised that the operation for removal of the larynx, which they had recommended, should not be undertaken.
The Lower Ganges canal, an extension of the original canal, has been in operation since 1878 and irrigates 830,000 acres.
Characteristic of the Rand is the fine white dust arising from the crushing of the ore, and, close to the batteries, the incessant din caused by the stamps employed in that operation.
The simplest types of process or operation are: (I), heating or cooling at constant volume, represented by vertical lines such as Bb, called Isometrics, in which the pressure varies, but no ex ternal work is done.
It was proposed to utilize the money set free by this operation to indemnify by a milliard francs the emigres for the loss of their lands at the Revolution; it was also proposed to restore their former privileges to the religious congregations.
In 18 99, 57 62 stamps were in operation, crushing 7,331,446 tons of ore, and yielding £15,134,000, equivalent to 25.5% of the world's production.
Similar plates are often used to catch any particles of gold that may be thrown back, while the main operation is so conducted that the bulk of the gold may be reduced to the state of amalgam by bringing the two metals into intimate contact under the stamp head, and remain in the battery.
Henry Wurtz in America (1864) and Sir William Crookes in England (1865) made independently the discovery that, by the addition of a small quantity of sodium to the mercury, the operation is much facilitated.
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 addition to the separation of the silver the operation extends to the elimination of the last traces of lead, tin, arsenic, &c. which have resisted the preceding cupeilation.
It used to be called " quartation " or " inquartation," from the fact that the alloy best suited for the operation of refining contained 3 parts of.silver to I of gold.
The operation may be conducted in vessels of glass or platinum, and each pound of granulated metal is treated with a pound and a quarter of nitric acid of specific gravity 1.32.
They are provided with lids, made either of lead or of wood lined with lead, which have openings to serve for the introduction of the alloy and acid, and a vent tube to lead off the vapours evolved during the operation.
These elements will enable us to convert, by a simple arithmetical operation, any historical date, of which the chronological characters are given according to any era whatever, into the corresponding date in the Christian era.
The operation was carried out exactly as ordered.
The operation had been brilliant in the extreme, but the exploitation proved more difficult, as neither tank nor artillery support was available in sufficient strength.
was brought up into line for this operation on the left of the 17th, the 21st Div.
Rawlinson then proposed to undertake an operation on a large scale with the object of capturing the outer defences of the Hindenburg line along the whole front of the Fourth Army.
The capture of these defences, which would afford observation over the greater part of the main Hindenburg line proper, was of course an essential preliminary to any operation against the latter.
The crossing of the narrow defile over the canal between Inchy and Moeuvres was carried out according to programme, thanks in large measure to the intensity of the barrage covering the operation.
The whole operation, investing as it did a most complicated and yet perfect combined action, had been a most brilliant success.
Another effort was made on the morrow to complete the operation.
The right division, the 52nd, successfully carried out this operation with a portion of its forces, while other units crossed the canal on the right in conjunction with the 63rd Div., and met with severe resistance.
The completion of the operation therefore was deferred till Oct.
Want of wind prevented the operation.
The battle of the 31st of July was the last serious operation of the war, though peace was not formally made till some months later.
Solids may be directly admitted to the tube from a weighing bottle, while liquids are conveniently introduced by means of small stoppered bottles, or, in the case of exceptionally volatile liquids, by means of a bulb blown on a piece of thin capillary tube, the tube being sealed during the weighing operation, and the capillary broken just before transference to the apparatus.
The weighing is conducted in the usual way by vibrations, except when the weight be small; it is then advisable to bring the pointer to zero, an operation rendered necessary by the damping due to the adhesion of water to the fibre.
There was only one country where its ravages were long unimportant; that was its home in the United States, where the native vines had become, by the operation of natural selection, immune to its attacks.
This transaction has given rise to much discussion as to its trustworthiness and the extent of its operation.
The advantage of the new definition lies in the fact that the estimation of the chlorine (or rather of the total halogen expressed as chlorine) is sufficient to determine the salinity by a very simple operation.
As cause of our sensations and ground of our belief in externality, he substituted for an unintelligible material substance an equally unintelligible operation of divine power.
