**theoretical**physics into the science of the aether.A train of ideas which strongly impressed itself on Clerk Maxwell's mind, in the early stages of his

**theoretical**views, was put forward by Lord Kelvin in 1858; he showed that the special characteristics of the rotation of the plane of polarization, discovered by Faraday in light propagated along a magnetic field, viz.The greatest obstacle to such a search for the fundamental medium is the illimitable complexity of matter, as contrasted with the

**theoretical**, forces on the question of the reconciliation between the free conscious organization of thought and the apparently necessitated and unconscious mechanism of the objective world.On

**theoretical**grounds it is probable that animatism preceded animism; but savage thought is no more consistent than that of civilized man; and it may well be that animistic and panthelistic doctrines are held simultaneously by the same person.The

The reaction known by his name for the detection of bile acids was published in 1844.Unfortunately considerations of luminosity compel the observer often to widen the slit much beyond the range within which the

**theoretical**value of resolving power holds in practice.**Theoretical**resolving power can only be obtained when the whole collimator is filled with light and further (as pointed out by Lord Rayleigh in the course of discussion during a meeting of the " Optical Convention " in London, 1905) each portion of the collimator must be illuminated by each portion of the luminous source.Though the experimental and

**theoretical**developments were not necessarily dependent on each other, and by far the larger proportion of the subject which we now term " Spectroscopy " could stand irrespective of Gustav Kirchhoff's thermodynamical investigations, there is no doubt that the latter was, historically speaking, the immediate cause of the feeling of confidence with which the new branch of science was received, for nothing impresses the scientific world more strongly than just that little touch of mystery which attaches to a mathematical investigation which can only be understood by the few, and is taken on trust by the many, provided that the author is a man who commands general confidence.He finds a remarkable agreement between the

**theoretical**and experimental values, which it would be important to confirm with the more suitable instruments which are now at our disposal, as we might in this way get an estimate of the energy of translatory motion of the luminous molecules.All these forms are put into the shade by that which was introduced by Ritz, led thereto apparently by

**theoretical**considerations.This is done in the hope that some

**theoretical**foundation may then be found for the equation.Further, according to Fichte, on the one hand the Ego posits itself as determined through the non-Ego - no object, no subject; this is the principal fact about

**theoretical**reason; on the other hand, the Ego posits itself as determining the non-Ego - no subject, no object; this is the principal fact about practical reason.Hence he united

**theoretical**and practical reason, which Kant had separated, and both with will, which Kant had distinguished; for he held that the Ego, in positing the non-Ego, posits both its own limit and its own means to the end, duty, by its activity of thinking which requires will.In making the essence of mind activity and construction, in destroying the separation of

**theoretical**and practical reason, in asserting that mind thinks things as means to ends of the will, he prepared the way for Schopenhauer and other voluntarists.They rightly revolted against the inconsistencies of Kant's third and fourth positions about the existence of unknown but postulated things in themselves, hidden from

**theoretical**, but revealed to practical, reason.If he has any originality, it consists in substituting for the association of ideas the " economy of thinking," by which he means that all

**theoretical**conceptions of physics, such as atoms, molecules, energy, &c., are mere helps to facilitate our consideration of things.Fichte's " Wissenschaftslehre," he said, is a completely untenable system, and a metaphysics of fruitless apices, in which he disclaimed any participation; his own Kritik he refused to regard as a propaedeutic to be construed by the Fichtian or any other standpoint, declaring that it is to be understood according to the letter; and he went so far as to assert that his own critical philosophy is so satisfactory to the reason,

**theoretical**and practical, as to be incapable of improvement, and for all future ages indispensable for the highest ends of humanity.He was in the habit of taking his students into the workshops, that they might acquire a practical as well as a

**theoretical**knowledge of different processes and handicrafts.They rejected Mr Chamberlain's food-taxes, discredited his statistics, and, while admitting the

**theoretical**restriction to of the temporal supremacy and religious power of the papacy, certain historical facts of great importance of France.By these decrees - which created as the supreme authority within the Church a power which had not been appointed as such by Christ 1 - the members of the council of Constance sought to give their position a

**theoretical**basis before proceeding to independent action against the pope.This is the earliest example of a

**theoretical**investigation of the rotation of rigid bodies.Willard Gibbs, who considered the whole problem of physical and chemical equilibrium in papers published in 1877, though the application of his principles only began to make extensive progress about twenty years after the publication of his purely

**theoretical**investigations.The pressure at each point should be that of the vapour, but since the solubility of a solid does not change much with pressure, measurements under the constant atmospheric pressure give a curve practically identical with the

**theoretical**one.The

**theoretical**form of the freezing point diagrams when solid solutions are present depends on the relation between the available energy and the composition in the two phases.It will be noticed that in all these

**theoretical**curves the points of initial fusion and solidification do not in general coincide; we reach a different curve first according as we approach the diagram from below, where all is solid, or from above, where all is liquid.The freezing and melting point curves are exactly similar to

**theoretical**curves of fig.But the elucidation of the complicated phenomena of solid solutions would have been impossible without the

**theoretical**knowledge deduced from the principle of available energy.Before considering the more complicated case of a concentrated solution, we will deal with one which is very dilute, when the

**theoretical**relations are much simplified.In practice the time required to reach these various conditions of equilibrium would be too great for experimental demonstration, but the

**theoretical**consideration of vapour pressures is of fundamental importance.When the solution ceases to be dilute in the thermodynamic sense of the word, that is, when the spheres of influence of the solute particles intersect each other, this reasoning ceases to apply, and the resulting modification of the gas laws as applied to solutions becomes a matter for further investigation,

**theoretical**or experimental.The experiments of Raoult on solutions of organic bodies in water and on solutions of many substances in some dozen organic solvents have confirmed this result, and therefore the

**theoretical**value of the osmotic pressure from which it was deduced.Although even good membranes of copper ferrocyanide are rarely perfectly semi-permeable, and in other membranes such as indiarubber, &c., which have been used, the defects from the

**theoretical**values of the equilibrium pressure are very great, yet, in the light of the exact verification of theory given by the experiments described above, it is evident that such failures to reach the limiting value in no wise invalidate the theory of osmotic equilibrium.They merely show that, in the conditions of the particular experiments, the thermodynamic equilibrium value of the osmotic pressure cannot be reached - the thermodynamic or

**theoretical**osmotic pressure (which must be independent of the nature of the membrane provided it is truly semi-permeable) is a different thing from the equilibrium pressure actually reached in a given experiment, which measures the balance of ingress and egress of solvent through an imperfect semi-permeable membrane.Dilute solutions of substances such as cane-sugar, as we have seen, give experimental values for the connected osmotic properties - pressure, freezing point and vapour pressure - in conformity with the

**theoretical**values.Even this correction is not sufficient in solution of sugar, where the

**theoretical**curve II lies below the experimental observations.The greater the number of water molecules attached to one sugar molecule, the less the residual volume, and the greater the

**theoretical**pressure.In practice the

**theoretical**quantity of acid and Chile saltpetre is not used, but the charge is so regulated that the mixture of acid and neutral sodium sulphate formed in the retort remains liquid at the temperature employed, and consequently can be readily removed.Among albino rats, for instance, the author of this article has reason to believe, upon

**theoretical**grounds resting on an experimental basis, that probably no less than thirteen types exist.These cases, however, have a peculiar interest and importance for they have been studied in fuller detail than any others and the discovery of a particular instance in South America first suggested to Bates the

**theoretical**explanation of this bionomical phenomenon.As a part of the voltage is consumed in the latter duty, only the residue can be converted into chemical work, and as the

**theoretical**voltage of the aluminium fluoride in the cryolite is 4.0, provided the bath is kept properly supplied with alumina, the fluorides are not attacked.We must observe, as regards the plants of the lower alpine region, that it is the actual presence of a forest vegetation, rather than the

**theoretical**treelimit, which affects their vertical distribution; so that, e.g.The most important

**theoretical**question concerning the Amphineura is how far do they represent the original condition of the ancestral mollusc?The length of the course as prescribed by law is two years, but it is usually extended to three or four years, and the instruction, though mainly

**theoretical**, has regard to the special local industries; the fees, if any, may not exceed one pound sterling per annum.The Zygomycetes, of which about 200 species are described, are especially important from a

**theoretical**standpoint, since they furnished the series whence Brefeld derived the vast majority of the fungi.The

**theoretical**question is consequently that of the nature of the supposed relation, and of the certainty of judgments and inferences resting on it.The results of Hume's

**theoretical**analysis are applied by him to the problems of practical philosophy and religion.The

**theoretical**efficiency of the wheel would then be Ioo %.Nevertheless, the

**theoretical**possibility, and its realization in many cases, has brought considerations to the front which have recently become of predominant interest; consequently the possible transformations of isomers and polymers will be considered later under the denomination of reversible or dynamical isomerisms.During the I9th century, however, a large measure of ecclesiastical self-government (by means of general synods, &c.) was introduced, pan passu with the growth of constitutional government in the state; and in effect, though the

**theoretical**supremacy of the sovereign survives in the church as in the state, he cannot exercise it save through the general synod, which is the state parliament for ecclesiastical purposes.While the Reichsrath, transferred to Kremsier, was discussing " fundamental rights " and the difficult question of how to reconcile the

**theoretical**unity with the actual dualism of the empire, the knot was being cut by the sword on the plains of Hungary.To a great extent the

**theoretical**and historical parts of his work are compiled from earlier Greek authors, of whom he gives a list at i.In any case, when Mahomet died, the separate pieces of the Koran, notwithstanding their

**theoretical**sacredness, existed only in scattered copies; they Trans= were consequently in great danger of being partially mission of or entirely destroyed.The action of atropine on the eye is of high

**theoretical**and practical importance.Ethics alone he considered worthy of study, and in that only general and

**theoretical**questions.But the word "pragmatism" itself first occurs in print in 1898, in James's pamphlet on

**Theoretical**Conceptions and Practical Results, and again in his Varieties of Religious Experience (1902, P. 444).It flattered his vanity to pose before the world as the dispenser of benefits; but his

**theoretical**liberalism was mated with an autocratic will which brooked no contradiction.The newly created council of ministers, and the senate, endowed for the first time with certain

**theoretical**powers, became in the end but the slavish instruments of the tsar and his favourites of the moment.Co-operation of the two factors appears to supply a causal theory of the occurrence of evolution; the suggestion of their co-operation and the comparison of the possible results with the actual achievements of breeders in producing varieties were the features of Charles Darwin's

**theoretical**work which made it a new beginning in the science of biology, and which reduced to insignificance all earlier work on the theory of evolution.Weismann, however, from

**theoretical**considerations and from analysis of supposed cases has at the least thrown doubt on the transmission of acquired characters.It is plain that whilst the existence of variation can be demon strated and the occurrence of evolution established by induction and deduction, the part played by selection must remain largely

**theoretical**.It was not only in

**theoretical**but in academical matters that his sympathies were on the liberal side.The absurdity of excluding the plebeians from all but a merely

**theoretical**citizenship, based on the negative fact of freedom, seems to have become apparent before the close of the monarchical period.The medieval candidate for the doctorate in medicine, although required to have attended practice before presenting himself, discussed as his thesis a purely

**theoretical**question, often semi-theological in character, of which as an extreme example may be quoted " whether Adam had a navel."In 1816 he was invited to Jena to fill the chair of

**theoretical**philosophy (including mathematics and physics, and philosophy proper), and entered upon a crusade against the prevailing Romanticism.The

**theoretical**deductions which he drew from the consideration of these bodies were even more interesting and important than the bodies themselves.Again, it is certain that the

**theoretical**and practical morality of the sophists, regarded as a class, was " neither above nor below the standard of the age."In a word, the present writer agrees with Grote that the sophists were not a sect or school with common doctrine or method; that their

**theoretical**and practical morality was neither above nor below that of their age, being, in fact, determined by it; and that Plato and his followers are not to be regarded as the authorized teachers of the Greek nation, nor the sophists as the dissenters, but vice versa.These passages certainly prove that Bacon had very nearly, if not perfectly, arrived at

**theoretical**proof of the possibility of constructing a telescope and a microscope; but his writings give no account of the trial of an actual telescope, nor any detailed results of the application of a telescope to an examination of the heavens.This is such a practical drawback that the separation is generally 4ths or $ths of the

**theoretical**, and then the primary image viewed by the eye piece may be rather outside the field-lens, which is a great practical advantage, especially when a reticule has to be mounted in the primary focal plane, although the edge of the field is not quite achromatic under these conditions.An important factor which thus served to maintain the rites in a more or less stable condition was the predominance of what may be called the astral theology as the

**theoretical**substratum of the Babylonian religion, and which is equally pronounced in the religious system of Assyria.Animal sacrifice, libations, ritualistic purification, sprinkling of water, and symbolical rites of all kinds accompanied by short prayers, represent a religious practice which in the Babylonian-Assyrian religion, as in all religions, is older than any theology and survives the changes which the

**theoretical**substratum of the religion undergoes.In addition to its great

**theoretical**interest, this method possesses the advantage of being frequently the most accurate in practical application, since energy can be more accurately measured in other forms than in that of heat.The

**Theoretical**Value Of The Ratio S/S In This Case Would Be The Required 7/5.Jeans has shown that for this type of star the argument is open to

**theoretical**objection, so that Myers's result cannot be accepted.If the uniform distribution extends indefinitely, or as far as the telescope can penetrate, the star-ratio should have the

**theoretical**value 3.98, 1 any decrease in density or limit to the distribution of the stars will be indicated by a continual falling off in the star-ratio for the higher magnitudes.The new assistant scarcely came up to expectations in respect of confirming certain

**theoretical**views of his master's by the experiments set him to that end, and appears to have stated the discrepancy without reserve; but Berthollet nevertheless quickly recognized the ability displayed, and showed his appreciation not only by desiring to be Gay-Lussac's "father in science," but also by making him in 1807 an original member of the Societe d'Arcueil.It is the oscillation which Mill manifests between the conception of his formula as it is actually applicable to concrete problems in practice, and the conception of it as an expression of a

**theoretical**limit to practical procedure.Finally, it is on the whole in keeping with Mill's presuppositions to admit even in the case of the method of difference that in practice it is approximative and instructive, while the

**theoretical**formula, to which it aims at approaching asymptotically as limit, if exact, is in some sense sterile.Cognition manifestly needs the help of Reason even in its

**theoretical**use.The

**theoretical**indicator diagram is made up of two isothermal lines for the taking in and rejection of heat, and two lines of constant volume for the two passages through the regenerator.When that is done, the full value of Hamilton's grand step becomes evident, and the gain is quite as extensive from the practical as from the

**theoretical**point of view.As a matter of fact, the two terms A+B/0 are the most important in the

**theoretical**expression for the vapour-pressure given below.The empirical formulae above quoted must be compared and tested in the light of the

**theoretical**validity in orthodox Hinduism, whilst it has also undoubtedly exercised considerable influence in shaping sectarian belief, in promoting feelings of toleration towards the claims of rival deities; and in a tendency towards identifying divine figures newly sprung into popular favour with one or other of the principal deities, and thus helping to bring into vogue that notion of avatars, or periodical descents or incarnations of the deity, which has become so prominent a feature of the later sectarian belief.The
