**theoretical**system, but contain the matured reflections, more or less closely reasoned, of a man of great mental power looking out on the world as it appeared to a business man experienced in affairs.Berthollet's

**theoretical**views regarding the composition of the metallic oxides, and he also showed Berthollet's "zoonic acid" to be impure acetic acid (1802); but Berthollet (q.v.), so far from resenting these corrections from a younger man, invited him to become a member of the Societe d'Arcueil.The works of the ancient Greek geographers were translated into Arabic, and starting with a sound basis of

**theoretical**and practical," and the discipline of the institution is military in form and principle.Thus over a great part of Europe the Catholic Church was split up into territorial or national churches, which, whatever the

**theoretical**ties which bound them together, were in fact separate organizations, tending ever more and more to become isolated and self-contained units with no formal intercommunion, and, as the rivalry of nationalities grew, with increasingly little even of intercommunication.Abandoning therefore all a priori

**theoretical**assumption, Bashforth set to work to measure experimentally the velocity of shot and the resistance of the air by means of equidistant electric screens furnished with vertical threads or wire, and by a chronograph which measured the instants of time at which the screens were cut by a shot flying nearly horizontally.Experiment, however, showed that while the quotient on the left hand of this equation was fairly constant for a great number of substances, yet its value was not gR but 7 R; this means that the critical density is, as a general rule, 3.7 times the

**theoretical**density.Laplace is due the

**theoretical**proof that this function is independent of temperature and pressure, and apparent experimental confirmation was provided by Biot and Arago's, and by Dulong's observations on gases and vapours.AdvertisementFor

**theoretical**principles of the subject.The

**theoretical**absolutism of the sultan had, indeed, always been tempered not only by traditional usage, local privilege, the juridical and spiritual precepts of the Koran and the Sunnet, and their 'Ulema interpreters, and the privy council, but for nearly a century by the direct or indirect pressure of the European powers, and during the reigns of Abd-ul-Aziz and of Abd-ul-Hamid by the growing force of public opinion.Whatever the

**theoretical**foundations above mentioned.When the series is theoretically continuous, the

**theoretical**graph will be a continuous figure of which the lines actually drawn are ordinates.It is not likely that such a result will ever be fully attained in practice; but the case is worth stating, in order to show that there is no

**theoretical**limit to the concentration FIG.There is clearly no

**theoretical**limit to the resolving power of gratings, even in spectra of given order.According to the principle already laid down it can make but little difference in the principal direction corresponding to the first spectrum, provided each line lie within a quarter of an interval (a+d) from its

**theoretical**position.In

**theoretical**investigations these problems are usually treated as of two dimensions only, everything being referred to the plane passing through the luminous point and perpendicular to the diffracting edges, supposed to be straight and parallel.Zarlino's first

**theoretical**work was the Istitutioni Armoniche (Venice, 1558; reprinted 1562 and 1573).The Istitutioni and Dimostrationi Armoniche deal, like most other

**theoretical**works of the period, with the whole science of music as it was understood in the 16th century.Peligot's results, though called in question by Berzelius, have been amply confirmed by all subsequent investigators; only now, on

**theoretical**grounds, first set forth by Mendeleeff, we double Peligot's atomic weight, so that U now signifies 240 parts of uranium, while UO 3 stands as the formula of the yellow oxide, and UO 2 as that of Berzelius's metal.Since the value of µ for water is about, it follows that n must be at least unity for a rainbow to be formed; there is obviously no

**theoretical**limit to the value of n, and hence rainbows of higher orders are possible.They produced many eminent anatomists, but in the end seem to have become lost in

**theoretical**subtleties, and to have maintained too high a standard of literary cultivation.Unfortunately it was neither this nor his zeal for research that chiefly won him followers, but the completeness of his

**theoretical**explanations, which fell in with the mental habits of succeeding centuries, and were such as have flattered the intellectual indolence of all ages.His principles were welcomed as a return to nature by those who were weary of

**theoretical**disputes.The medicine of the i 8th century is notable, like that of the latter part of the 17th, for the striving after complete

**theoretical**systems. The influence of the iatro-physical school was by no means exhausted; and in England, especially through the indirect influence of Sir Isaac Newton's (1642-1727) great astronomical generalizations, it took on a mathematical aspect, and is sometimes known as iatro-mathematical.Their English contemporaries and successors, John Freind, William Cole, and Richard Mead, leaned also to mechanical explanations, but with a distrust of systematic

**theoretical**completeness, which was perhaps partly a national characteristic, partly the result of the teaching of Sydenham and Locke.George Ernest Stahl (1660-1734) was for more than twenty years professor of medicine at Halle, and thus a colleague of Hoffmann, whom he resembled in constructing a complete

**theoretical**system, though their systems had little or nothing in common.The

**theoretical**differences between this and the" stimulus "theory need not be expounded.From a

**theoretical**point of view Hahnemann's is one of the abstract systems, pretending to universality, which modern medicine neither accepts nor finds it worth while to controvert.But these indirect benefits were quite independent of the truth or falsity of his

**theoretical**system.Among the most ardent of his followers was Francois Joseph Victor Broussais (1772-1838), whose

**theoretical**views, partly founded on those of Brown and partly on the so-called vitalist school of Theophile Bordeu (1722-1776) and Paul Joseph Barthez (1734-1806), differed from these essentially in being avowedly based on anatomical observations.Hardly any

**theoretical**system is of English birth; Erasmus Darwin (1731-1802), the grandfather of the great Charles Darwin, alone makes an exception.Dr Hopkinson presented a rare combination of practical with

**theoretical**ability, and his achievements in pure scientific research are not less intrinsically notable than the skill with which he applied their results to the solution of concrete engineering problems. His original work is contained in more than sixty papers, all written with a complete mastery both of style and of subject-matter.This " barrage scheme " was discussed at considerable length, and its

**theoretical**advantages were not universally admitted.Referring the reader to the article Elasticity for the

**theoretical**and to the Strength Of Materials far the practical aspects of this subject, we give here a table of the "modulus of elasticity," E (column 2), for millimetre and kilogramme.For the

**theoretical**side he read all the text-books which he could find, somewhat to the detriment of his ordinary school studies.In the case of the motion of the moon around the earth, assuming the gravitation of the latter to be subject to the modification in question, the annual motion of the moon's perigee should be greater by I 5" than the

**theoretical**motion.Brown is the first investigator to determine the

**theoretical**motions with this degree of precision; and he finds that there is no such divergence between the actual and the computed motion.Frontinus also wrote a

**theoretical**treatise on military science (De re militari) which is lost.In addition he wrote (1863) on

**theoretical**and physical chemistry for the Graham-Otto Lehrbuch der Chemie, and for many years assisted Liebig in editing the Annalen der Chemie and the Jahresbericht.As the practical work depends on the conclusions of the

**theoretical**, the latter must obviously come first in order of execution.But as the claims of the church to be the guardian through its episcopate of the apostolic tradition, of the Christian faith itself, were magnified, and unity in practice as well as in doctrine came to be regarded as essential, this distinction became a

**theoretical**rather than a practical one.**Theoretical**conceptions were revived by Stahl, who held that acids were the fundamentals of all salts, and the erroneous idea that sulphuric acid was the principle of all acids.A

**theoretical**supremacy was accorded by the Incas to Pachacamac, whose worship, like that of Vira cocha, they appear to have already found when they conquered the land.The

**theoretical**aspect is discussed in Leon Guillet's Etude theorique des alliages metalliques (2904).But this simple relation is only true of the net balances of heat and work in a complete cyclical process, which must be adopted for

**theoretical**purposes if we wish to eliminate the unknown changes of intrinsic energy.Taking this ideal limit as a

**theoretical**or absolute zero, the value of H may be represented on the diagram by the whole area included between the two adiabatics BAZ, CDZ' down to the points where they intersect the isothermal of absolute zero, or the zero isopiestic OV asymptotically at infinity.In the modified Joule-Thomson equation (17), both c and n have simple

**theoretical**interpretations, and it is possible to express the thermodynamical properties of the substance in terms of them by means of reasonably simple formulae.The values of the corresponding functions for the liquid or solid cannot be accurately expressed, as the

**theoretical**variation of the specific heat is unknown, but if we take the specific heat at constant pressure s to be approximately constant, and observe the small residual variation dh of the total heat, we may write F'=s'D+dh+B'.The important part played by the residual air in the globe had also been deduced by Osborne Reynolds from observing that on turning off the light, the vanes came to rest very much sooner than the friction of the pivot alone would account for; in fact, the rapid subsidence is an illustration of Maxwell's great

**theoretical**discovery that viscosity in a gas (as also diffusion both of heat and of the gas itself) is sensibly independent of the density.A general introduction to the system is given in the tractate Ober den Begriff der Wissenschaftslehre (On the Notion of the Theory of Science), 1794, and the

**theoretical**portion is worked out in the Grundlage der gesammten Wissenschaftslehre (Foundation of the whole Theory of Science, 1794) and Grundriss des Eigenthiimlichen d.The last is probably the most important of all Fichte's works; apart from it, his

**theoretical**philosophy is unintelligible.As determined the ego is

**theoretical**, as determining it is practical; ultimately the opposed principles must be united by showing how the ego is both determining and determined.But more important than all this, perhaps, is the thoroughly practical tone which Guido assumes in his

**theoretical**writings, and which differs greatly from the clumsy scholasticism of his contemporaries and predecessors.Gioja's latest work Filosofia della statistica (2 vols., 1826; p vols., 1829-1830) contains in brief compass the essence of his ideas on human life, and affords the clearest insight into his aim and method in philosophy both

**theoretical**and practical.Barton, A Text-Book on Sound (1908), aims to provide students with a text-book on sound, embracing both its experimental and

**theoretical**aspects.When the psalmist declares that " the fool hath said in his heart, there is no God," he probably does not refer to

**theoretical**denial, but to a practical disbelief in God's government of human affairs, shown in disobedience to moral laws.It must be judged not only by

**theoretical**but by practical arguments, in its relations either to the individual or to a society.In a three-span bridge the

**theoretical**advantage of continuity is about 49% for a dead load and 16% for a live load.Professor Claxton Fidler (Treatise on Bridge Construction, 1887) has made a very careful

**theoretical**analysis of the weights of bridges of different types, and has obtained the following values for the limiting spans.During this period they receive regular instruction in

**theoretical**and practical knowledge, and have to pass periodical examinations.This description, quoted from James Clerk Maxwell's article in the 9th edition of the Encyclopaedia Britannica, represents the historical position of the subject up till about 1860, when Maxwell began those constructive speculations in electrical theory, based on the influence of the physical views of Faraday and Lord Kelvin, which have in their subsequent development largely transformed

**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**simplicity and uniformity of the physical agencies which connect together its different parts.For purposes of

**theoretical**discussions relating to moving radiators and reflectors, it is important to remember that the dynamics of all this theory of electrons involves the neglect of terms of the order (v/c) 2, not merely in the value of K but throughout.But no formula has yet been invented, derived on

**theoretical**principles from the physical data, which will assign by calculation a definite magnitude to 3.After his victory over Banks at Cedar Mountain, near Culpeper, Virginia, Jackson led the daring march round the flank of General Pope's army, which against all

**theoretical**rules ended in the great victory of second Bull Run.The first or

**theoretical**part deals with the high origin of the human soul, and shows how it has departed from its first estate.There are also grave

**theoretical**objections to Cauchy's formula.The

**theoretical**side of inner nature in its successive grades from sensation to the highest form of spirit, the abstracting reason which emphasizes the difference of subjective and objective, leaves an unsolved problem which receives satisfaction only in the practical, the individualizing activity.The practical, again, taken in conjunction 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

**theoretical**powers of these comitia were extensive both in the election of magistrates and in legislation.Whatever

**theoretical**reasons there may be for assuming his earlier existence, they must be held as warranting no more than a presumptive conclusion, which up to the present time lacks confirmation by certain evidence.If, however, application be made of the rate in its entirety from 1790 to 1900, the result would be a

**theoretical**pure native stock in 1900 equal to the then actually existing native and foreign stock combined.The college includes a school for teachers, a school of

**theoretical**and practical agriculture and a school of household science for the training of young women.In his earlier years he devoted himself to chemistry, both

**theoretical**and applied, publishing papers on the preparation of gold and platinum, numerical relations between the atomic weights of analogous elements, the formation of aventurine glass, the manufacture of illuminating gas from wood, the preservation of oil-paintings, &c. 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**orthodoxy of retaliation, criticized Mr Balfour's attitude and repudiated his assumption that retaliation would be desirable.Although there was no

**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
