Ewing (Magnetic Induction, § 194) has devised an arrangement in which two similar test bars are placed side by side; each bar is surrounded by a magnetizing coil, the two coils being connected to give opposite directions of magnetization, and each pair of ends is connected by a short massive block of soft iron having holes bored through it to fit the bars, which are clamped in position by set-screws.
If, however, the permeability of the test rod differs from that of the standard, the number of lines of induction flowing in opposite directions through the two rods will differ, and the excess will flow from one yoke to the other, partly through the air, and partly along the path provided by the bent bars, deflecting the compass needle.

It may be readily deduced that the directions of minimum deviation for a pencil of parallel rays lie on the surface of cones, the semi-vertical angles of which are equal to the values given in the above table.
This was first suggested by Thomas Young, who showed that the rays producing the bows consisted of two systems, which, although emerging in parallel directions, traversed different paths in the drop.

As far as the order to which he carried the approximations - which, however, were based on a simplifying hypothesis that the molecules influenced each other through mutual repulsions inversely as the fifth power of their distance apart--the result was that the equations of motion of the gas, considered as subject to viscous and thermal stresses, could be satisfied by a state of equilibrium under a modified internal pressure equal in all directions.
Reynolds, in his investigation, introducing no new form of law of distribution of velocities, uses a linear quantity, proportional to the mean free path of the gaseous molecules, which he takes to represent (somewhat roughly) the average distance from which molecules directly affect, by their convection, the state of the medium; the gas not being uniform on account of the gradient of temperature, the change going on at each point is calculated from the elements contributed by the parts at this particular distance in all directions.

He proposed the term " mutations " for the minute progressive changes of single characters in definite directions as observed in successive stratigraphic levels.
This definitely directed evolution, or development in a few determinable directions, has since been termed " orthogenetic evolution," and is recognized by all workers in invertebrate palaeontology and phylogeny as fundamental because the facts of invertebrate palaeontology admit of no other interpretation.
Starting with the stem forms the descendants of which have passed through either persistent or changed habitats, we reach the underlying idea of the branching law of Lamarck or the law of divergence of Darwin, and find it perhaps most clearly expressed in the words "adaptive radiation" (Osborn), which convey the idea of radii in many directions.
Among extinct Tertiary mammals we can actually trace the giving off of these radii in all directions, for taking advantage of every possibility to secure food, to escape enemies and to reproduce kind; further, among such well-known quadrupeds as the horses, rhinoceroses and titanotheres, the modifications involved in these radiations can be clearly traced.
The only inkling of possible underlying principles in this orderly process is that there appears to be in respect to certain characters a potentiality or a predisposition through hereditary kinship to evolve in certain definite directions.
Medusae capture their prey, consisting of small organisms of various kinds, especially Crustacea, by means of the tentacles which hang out like fishing-lines in all directions.
Scarcely was the Society launched when its members dispersed in various directions to their new tasks.
The country about the Laguna de Terminos is low and flat, and is traversed in all directions by deep, sluggish streams. Many of the rivers crossing the lowlands bordering the Gulf have short navigable channels, the most important of which is the Panuco and its tributaries.
When this large body of scholars were set down to their task, an elaborate set of rules was drawn up for their guidance, which contained a scheme of revision as well as general directions for the execution of their work.
Thus, animism is in some directions little developed, so far as we can see, among the Australian aborigines; but from those who know them best we learn that they believe in innumerable spirits and bush bogies, which wander, especially at night, and can be held at bay by means of fire; with this belief may be compared the ascription in European folk belief of prophylactic properties to iron.
The old town centres in the Plaza del Mercado, from which narrow and tortuous lanes radiate in various directions; the new one dates, from about the middle of the 18th century, and its streets are wide and straight.
The remaining fragments were, under the directions of the Royal Society, reduced by Dr Wallis to a compact form, with the heading Astronomia Kepleriana defensa et promota, and published with numerous extracts from the letters of Horrocks to Crabtree, and a sketch of the author's life, in a volume entitled Jeremiae Horroccii opera posthuma (London, 1672).
But many of the directions are much too serious and fundamental to have been given in this form; one can hardly imagine that Paul considered Timothy (or Titus) still in need of elementary advice and warning upon such matters, and especially on personal purity.
In addition to these non-marine formations of the west, there is the widespread Lafayette formation, which covers niuch of the Atlantic and Gulf coastal plain, reaching far to the north from the western Gulf regio,1, and having uncertain limits, so far as now worked out, in various directions.
After the war of 1812 new outlets were found in all directions, and the I
In the course of time the status of the ceorl was probably reduced; but although his political power was never large, and in some directions his freedom was restricted, it hardly seems possible previous to the Norman Conquest to class him among the unfree.
In 1788 when the Danes unexpectedly invaded Sweden and threatened Gothenburg, it was Armfelt who under the king's directions organized the Dalecarlian levies and led them to victory.
He extended the rights of the natives, and in certain directions curtailed the privileges of Europeans.
The divide between the rivers flowing west and those flowing east and north is very sharp in the southern Rocky Mountains, but there are two lakes, the Committee's Punch Bowl and Fortress Lake, right astride of it, sending their waters both east and west; and there is a mountain somewhat south of Fortress Lake whose melting snows drain in three directions into tributaries of the Columbia, the Saskatchewan and the Athabasca, so that they are distributed between the Pacific, the Atlantic (Hudson Bay) and the Arctic Oceans.
After The Dates Of Commencement Of The Successive Hebrew Years Are Finally Adjusted, Conformably With The Foregoing Directions, An Estimation Of The Consecutive Intervals, By Taking The Differences, Will Show The Duration And Character Of The Years That Respectively Intervene.
Mazarin was not a Frenchman, but a citizen of the world, and always paid most attention to foreign affairs; in his letters all that could teach a diplomatist is to be found, broad general views of policy, minute details carefully elaborated, keen insight into men's characters, cunning directions when to dissimulate or when to be frank.
Main lines run also from Turin toVercelli and thence to Novara and Milan (the direct route), to Casale Monferrato, to Alessandria (and thence to Piacenza or Genoa), to Genoa via Asti and Acqui, to Bra and Savona, and branch lines to Lanzo, Torre Pellice, Aosta, Rivoli, Rivarolo, &c., and steam tramways in various directions.
It is connected with the Zuider Zee by a fine canal protected by a large sea-lock (1828), and has regular steam-boat communication in various directions.
As a fact, the commanders-in-chief on the East Indies and Cape of Good Hope stations were instructed that in consequence of the great practical difficulty of proving - at ports so remote from the scene of war operations as Aden and Perim - the real destination of contraband of war carried by vessels visiting those parts, directions were to be given to the officers concerned to cease to search such vessels, and to merely report to the commander-in-chief at the Cape the names of ships suspected of carrying contraband, and the date of clearance.
The main effects we have to discuss are (I) a symmetrical widening, (2) a shift of wave-length, which when it accompanies expansion in both directions may appear as an unsymmetrical widening, (3) a change in the relative intensities of the lines.
The cadmium line having a wave-length of 2288 A broadens by pressure equally in both directions, but if mercury be added the broadening is more marked on the less refrangible side.
The establishment of Dominion government agencies, the formation of a local government, the machinery required for the government of the province, the influx of a small army of surveyors who mapped out and surveyed wide districts of the country, and the taking up of free lands in all directions by Canadian settlers, all tended to build up the hamlet of Winnipeg into a considerable town.
Somewhere about this period of More's life two things happened which gave in opposite directions the determining impulse to his.
On the other hand, under the influence of the mechanics of his day, which had hardly distinguished between inertia, or the inability of a body to change itself, and resistance or the ability of bodies to oppose one another, he concluded that, as inertia is passive, so is resistance, and refused to recognize that in collision the mutual resistance of moving bodies is a force, or active power, of changing their movements in opposite directions.
Asturias consists of a portion of the northern slope of the Cantabrian Mountains,and is covered in all directions with offshoots from the main chain, by which it is almost completely shut in on the south.
Following the first chart of lines of equal variation compiled by Edmund Halley in 1700, charts of similar type have been published from time to time embodying recent observations and corrected for the secular change, thus providing seamen with values of the variation accurate to about 30' of arc. Possessing these data, it is easy to ascertain by observation the effects of the iron in a ship in disturbing the compass, and it will be found for the most part in every vessel that the needle is deflected from the magnetic meridian by a horizontal angle called the deviation of the compass; in some directions of the ship's head adding to the known variation of the place, in other directions subtracting from it.
The additions of velocity which the two bodies receive respectively, relative to such a base, are in opposite directions, and if the bodies are alike their magnitudes are equal.
When, as in the case of contact, a mutual relation is perceived between the motions of two particles, the changes of velocity are in opposite directions, and the ratio of their magnitudes determines the ratio of the masses of the particles; the motion being reckoned relative to any base which is unaffected by the change.
The Galileo-Newton theory of motion is that, relative to a suitably chosen base, and with suitable assignments of mass, all accelerations of particles are made up of mutual (so-called) actions between pairs of particles, whereby the two particles forming a pair have accelerations in opposite directions in the line joining them, of magnitudes inversely proportional to their masses.
Thus each mutual action is associated with a pair of equal forces in opposite directions.
No correction for any defect in it has been found necessary; moreover, no rotation of the base relative to the directions of the stars without proper motion has been detected.
The movement in opposite directions of these charged ions constitutes the electric current in the solution.
But recent experiments have shown that the simple theory of coagulation here outlined needs amplification in certain directions.

Gears are provided for elevating, levelling, aligning the upper and lower optical systems, adjusting the inclination of the reflector and rotating the mast around a vertical axis so that observations may be made and azimuth angles taken in all directions.
This ceased at Rome at the same time as the apparel disappeared; but two relics of it survive - (I) in the directions of the Missal for putting on the amice, (2) in the ordination of subdeacons, when the bishop lays the vestment on the ordinand's head with the words, "Take the amice, which symbolizes discipline over the tongue, &c."
In the case of the two leading Church of England societies, the bishops (being members) are ex officio on all executive committees; but their labours in other directions prevent their ordinarily attending.
In shape Milan is a fairly regular polygon, and its focus is the splendid Piazza del Duomo, from which a number of broad modern streets radiate in all directions.

Pruning, or the removal of superfluous growths, is practised in order to equalize the development of the different parts of trees, or to promote it in particular directions so as to secure a certain form, and, by checking undue luxuriance, to promote enhanced fertility.
Care should be taken, however, not to hem in the garden by crowded plantations, shelter from the prevailing strong winds being all that is required, while the more open it is in other directions the better.
As therefore the disks revolve, these carriers travel in opposite directions, coming at intervals in opposition to each other.
Besides the Reit Diep, there are the Ems Canal and the Damster Diep, connecting it with Delfzyl and the Dollart, the Kolonel's Diep with Leeuwarden, the Nord Willem's Canal with Assen and the south and the Stads-Canal south-east with the Ems. Hence steamers ply in all directions, and there is a regular service to Emden and the island of Borkum via Delfzyl, and via the Lauwers Zee to the island of Schiermonnikoog.
The remarkable stability of the mountain appears to be due to the innumerable dikes which penetrate the lava flows and tuff beds in all directions and thus bind the whole mass together.
The notes of this journey are written in a light and amusing style, showing Hume's usual keenness of sight in some directions and his almost equal blindness in others.
The new house to which he alludes was built under his own directions at the corner of what is now called St David Street after him; it became the centre of the most cultivated society of Edinburgh.
These plateaus, with an average elevation of Boo to 1000 ft., are mostly covered with forests of oak, beech and lime, and are deeply cut by river valleys, some being narrow and craggy, and others broad, with gentle slopes and marshy bottoms. Narrow ravines intersect them in all directions, and they often assume, especially in the east, the character of wild, impassable, woody and marshy tracts.
We find traces of such additions within the New Testament itself in such directions as are contained in Col.

The management of the Prussian railway system is committed to the charge of twenty directions, into which the whole network of lines is divided, being those of Altona, Berlin, Breslau, Bromberg, Danzig, Elberfeld, Erfurt, Essen ad.
It is probable, therefore, that in other directions also the Germans had considerably advanced their frontier southwards at a comparatively recent period.
It is in these directions that the reign of Henry the Fowler marks a stage in the history of, ,Germany.
Yet, notwithstanding his policy, in these directions the German nobles appear to have been enthusiastically devoted to Frederick.
In other directions, however, he was more fortunate.

In 1576, when Milan was visited by the plague, he went about giving directions for accommodating the sick and burying the dead, avoiding no danger and sparing no expense.
Even smaller mean values have been found for the angle between the auroral and magnetic " zeniths " - as the two directions have been called - e.g.
Birkeland (19), who has made a special study of magnetic disturbances in the Arctic, proceeding on the hypothesis that they arise from electric currents in the atmosphere, and who has thence attempted to deduce the position and intensity of these currents, asserts that whilst in the case of many storms the data were insufficient, when it was possible to fix the position of the mean line of flow of the hypothetical current relatively to an auroral arc, he invariably found the directions coincident or nearly so.
At Tasiusak (10) in 1898-1899 the magnetic directions of the principal types were noted separately.
One end only, for example, may appear to move, as if rotating round the other; or the two ends may move in opposite directions, as if the arc were rotating about a vertical axis through its summit.
Under such directions the Murabtis were brought to excellent order.
Motion of the ground in the direction os actuates only the lever so'p', motion in the direction o's actuates only sop, whilst motion in inter mediate directions actuates both.
So much for abrogated readings; the case is somewhat different when we come to the abrogation of laws and directions to the Moslems, which often occurs in the Koran.
Thus, for example, the Koran contains very different directions, suited to varying circumstances, as to the treatment which idolaters are to receive at the hands of believers.
Believers receive general moral instruction, as well as directions for special circumstances.
A part of the Medina pieces consists of formal laws belonging to the ceremonial, civil and criminal codes; or directions about certain temporary complications.
The death of Heinrich Brugsch in 1895 was a very severe blow to demotie studies; but it must be admitted that his brilliant gifts lay in other directions than exact grammatical analysis.
This method was carried on up to the point of getting contact with the facingplate at every inch of the surface; the cuts cross in various directions.
This continuum was held to render possible conduction in all directions throughout the grey matter of the whole nervous system.
The fact that conduction occurred preponderantly in certain directions was explained by appeal to a hypothetical resistance to conduction which, for reasons unascertained, lay less in some directions than in others.
Among the properties of the neuron is conductivity in all directions.
It is a plausible conjecture that the original narratives of J and E also contained directions for the construction of an ark,' as a substitute for the personal presence of Yahweh, and also for the erection of a "tent of meeting" outside the camp, and that these commands were omitted by R P in favour of the more elaborate instructions given in ch.
Extensions of pragmatism in a variety of directions readily suggest themselves, and indeed only the doctrine of truth in the above sketch can be treated as strictly indispensable.
There is no exclusive apical growth, and the cells divide in all directions.
On some of the platforms there are upwards of a dozen images, now thrown from their pedestals and lying in all directions.
Where a rock yields to weather with considerable uniformity in all directions it is likely to assume conical forms in the progress of denudation.
In 1833 Scottish burghs were for the first time entitled to be governed by directly-elected bodies, and at various times since that date fuller powers of legal self-government were granted in different directions.
But there are several directions in which the field of variation appears to be not only limited but defined in a certain direction.
The book contains rules for the conduct of the anchoresses, and gives liturgical directions for divine service; but the greater part of it is taken up with the purely spiritual side of religion.
Information as to the field sports of the ancients is in many directions extremely fragmentary.
While in some counties the sport has suffered, towns men who formerly would have been too far from a meet can now secure transport for themselves and their horses in all directions; and as a consequence, meets of certain packs are not advertised because of the number of strangers who would be induced to attend.
Round about London a man who is bent on the pursuit of fox or stag may gratify his desire in many directions.
The Franco-German War engaged Flach's activities in other directions, and he spent two years (described in his Strasbourg apres le bonabardement, 1873) at work on the rebuilding of the library and the museum, which had been destroyed by Prussian shells.
Many of these risings were due to the intrigues of the Church party, and in view of these circumstances President Alfaro curtailed the influence of the clergy in several directions.
It consists of two parabolic branches tending in opposite directions.
Incidentally this involved an extension of plebeian privilege in two directions.
When there are fissures radiating in several directions it is called "star shake."
This last sentence has led some modern writers to suppose that he made two different voyages; but this is improbable; the expressions of Polybius imply that his explorations in both directions, first towards the north and afterwards towards the east, formed part of the same voyage.
While they are journeying two and two in various directions St Mark takes occasion to tell us the current conjectures as to who Jesus really was.
Since CE equals BE these directions are equally inclined to, and coplanar with, the normal to the mirror.
But in those forms where curving must take place in different directions the layers or fibres of metal are made to glide over one another, extension taking place in some layers but not in others, and this goes on without producing much reduction in the thickness.

The shaken masses then gave way one after the other, and the Scots fled in all directions.
Later on, by the discovery of a new continent, commerce was diverted into new directions.
But the name of Clive exercised a decisive effect in both directions.
In the sailing directions, issued in 1561, for the use of this expedition the phrase " las Islas Filipinas " was used as applying to the entire archipelago.
If both the bodies are luminous, especially if they do not differ much in brilliancy, the motion of revolution is shown by a periodic doubling of the lines of the spectrum; when one body is moving towards us and the other away their spectral lines are displaced (according to Doppler's principle) in opposite directions, so that all the lines strong enough to appear in both spectra appear double; when the two bodies are in conjunction, and therefore moving transversely, their spectra are merged into one and show nothing unusual.
The Streams. motion of the stars in the mean towards Canis Major is thus a resultant motion, which, when examined more minutely, is found to be due to the intermingling of two great streams of stars moving in very different directions.
This hypothesis of two star-drifts does not imply that all the stars move in one or other of two directions.
The older one - which may be called the " one-drift " hypothesis, since according to it the stars appear to form a single drift moving away from the solar apex - requires that the apparent directions of motion should be so distributed that fewest stars are moving directly towards the solar apex, and most stars along the great circle away from the solar apex, the number decreasing symmetrically, for directions inclined on either side of this great circle, according to a law which can be calculated.
The deviation is unmistakable; in general the direction from the solar apex is not the one in which most stars are moving; and, what is even more striking, the directions, in which most and fewest stars respectively move, are not by any means opposite to one another.
Our first inquiry is whether the universe extends indefinitely in all directions, or whether there are limits beyond which the stars Limits of are not distributed.
Various considerations tend to show that this apparent crowding does not imply a really greater density or clustering of the stars in space, but is due to the fact that in these directions we look through a greater depth of stars before coming to the boundary of the stellar system.
Imagine this stratum to be uniformly filled with stars (of course in the actual universe instead of sharply defined boundaries AB and CD, we shall have a gradual thinning out of the stars) it follows that in the two directions SP and SP' the fewest stars will be seen; these then are the directions of the galactic poles.
As we consider a direction such as SQ farther and farther from the pole the boundary of the universe in that direction becomes more and more remote so that more stars are seen, and finally in the directions SR and SR' in the galactic plane, the boundary is perhaps beyond the limits of our telescopes.
That the universe must have a boundary in the directions SR and SR', we can hardly doubt, but nothing is known of its shape or distance except that in all directions it must be far greater than SP or SP'; in particular it is not known whether the sun is near the centre or otherwise.
A glance at the Milky Way, with its sharply defined irregular boundaries, its clefts and diverging spur, is almost sufficient to assure us that it is a real cluster of stars, and does not merely indicate the directions in which the universe extends farthest.
The god here states that he is about to send a deluge, which will cause destruction to all mankind, and he gives directions for the building of a great ship in which "the beasts of the field and the birds of heaven" may be saved, along with Ut-napishtim and his family; he fixes the size of the ship and directs that it should be covered with a strong roof or deck.
His services to industry included his improvements in the processes for the manufacture of sulphuric acid (1818) and oxalic acid (1829); methods of estimating the amount of real alkali in potash and soda by the volume of standard acid required for neutralization, and for estimating the available chlorine in bleaching powder by a solution of arsenious acid; directions for the use of the centesimal alcoholometer published in 1824 and specially commended by the Institute; and the elaboration of a method of assaying silver by a standard solution of common salt, a volume on which was published in 1833.
As was to be expected, they were worsted; eleven small flying columns of the Moslems, sent out in various directions, sufficed to quell the revolt.
After the restoration of peace his capacity for organization was displayed in all directions.
The fact that a great number of these serfs had been enjoying protection as free ceorls in former ages made itself felt, however, in three directions.
Quaternions (as a mathematical method) is an extension, or improvement, of Cartesian geometry, in which the artifices of co-ordinate axes, &c., are got rid of, all directions in space being treated on precisely the same terms. It is therefore, except in some of its degraded forms, possessed of the perfect isotropy of Euclidian space.
Also let us assume (a) space to have the same properties in all directions, and make the convention (b) that to change the sign of any one factor changes the sign of a product.
Here the symmetry points at once to the selection of the three principal axes as the directions for i, j, k; and it would appear at first sight as if quaternions could not simplify, though they might improve in elegance, the solution of questions of this kind.
There is no proper nucleus of mountains whence chains ramify in different directions.
We have seen that Thales recognized change, but attempted no explanation; that Anaximander spoke of change in two directions; that Anaximenes called these two directions by specific names.
After a long repose Ometepe also burst into renewed activity on the 19th of June 1883, when the lavas from a new crater began to overflow and continued for seven days to spread in various directions over the whole island.
They have a sort of chart, medo, of small sticks tied together, representing the positions of islands and the directions of the winds and currents.
In these latter cases the reaction may proceed in different directions; thus, with the aromatic hydrocarbons, chlorine in the cold or in the presence of a carrier substitutes in the benzene nucleus, but in the presence of sunlight or on warming, substitution takes place in the side chain.
Just as two or more forces can be combined into a single resultasit, so a single force may be resolved into components acting in assigned directions.
Thus a fdrce can be uniquely resolved into two components acting in two assigned directions in the same plane with it by an inversion of the parallelogram construction of fig.
If, as is usually most convenient, the two assigned directions are at right angles, the two components of a force P will be P cos 0, P sin 0, where 0 is the inclination of P to the direction of the p former component.
If the origin of rectangular axes fixed in the lamina be shifted through a space whose projections on the original directions of the axes are X, u, and if the axes are simultaneously turned through an angle e, the coordinates of a point of the lamina, relative to the original axes, are changed from x, y to X+x cos ey sin e, u+x sin e+y cos e, or X + x ye, u + Xe + y, ultimately.
Again it is necessary and sufficient for equilibrium that the sum of the projections of the forces on each of two perpendicular directions should vanish, and (moreover) that the sum of the moments about some one point should be zero.
If now the assemblage be brought into any other position relative to the earth, without alteration of the mutual distances, this is equivalent to a rotation of the directions of the forces relatively to the assemblage, the ratios of the forces remaining unaltered.
We have only to construct the line of action of the resultant for each of two arbitrary directions of the forces; the intersection of the two lines gives the point required.
