Carrying on the same analytical method into the special department of moral philosophy, Green held that ethics applies to the peculiar conditions of social life that investigation into man's nature which metaphysics began.
The faculty employed in this further investigation is no "separate moral faculty," but that same reason which is the source of all our knowledge - ethical and other.

The investigation of the microscopic pelagic life of the sea has also developed to a great extent.
The second relation, as we have seen, is not a strict consequence of theory, and experiments to examine it must be treated as an investigation of the limits within which solutions are dilute within the thermodynamic sense of the word, rather than as a test of the soundness of the theory.
The result of the investigation shows that the electrical work Ee is given by the_equation Ee =1 where v is the volume of the solution used and p its osmotic pressure.
During the next eight years he carried out a minute investigation of this metal and its properties.
Apart altogether from the facts that this investigation is still in its infancy and that the conditions of experiment are insufficiently understood, its ultimate success is rendered highly problematical by the essential fact that real scientific results can be achieved only by data recorded in connexion with a perfectly nortnal subject; a conscious or interested subject introduces variable factors which are probably incalculable.
Thomson (afterwards Lord Kelvin) in 1847, as the result of a mathematical investigation undertaken to explain Faraday's experimental observations.

On the 19th of July 1866 he was working at his last unfinished investigation on the mechanism of the ear.
The calculus of variations lay undeveloped in Euler's mode of treating isoperimetrical problems. The fruitful method, again, of the variation of elements was introduced by Euler, but adopted and perfected by Lagrange, who first recognized its supreme importance to the analytical investigation of the planetary movements.
The final achievement of Lagrange in this direction was the extension of the method of the variation of arbitrary constants, successfully used by him in the investigation of periodical as well as of secular inequalities, to any system whatever of mutually interacting bodies.'

His investigation of the properties of amicable numbers and of the problem of trisecting an angle, are of importance.
Cuvier's morphological doctikne received its fullest development in the principle of the " correlation of parts," which he applied to palaeontological investigation, namely, that every animal is a definite whole, and that no part can be varied without entailing correlated and law-abiding variations in other parts, so that from a fragment it should be possible, had we a full knowledge of the laws of animal structure or morphology, to reconstruct the whole.
The immediate result was, as pointed out above, a reconstruction of the classification of animals upon a genealogical basis, and an investigation of the individual development of animals in relation to the steps of their gradual building up by cell-division, with a view to obtaining evidence of their genetic relationships.
Whatever value is to be attached to Mendel's observation of the breaking up of self-fertilized hybrids of cultivated varieties into the two original parent forms according to the formula " 'PP, 2PN, INN," it cannot be considered as more than a contribution to the extensive investigation of heredity which still remains to be carried out.

Jonah is the Kitab al Tank (" Book of Exact Investigation"), which consists of two parts, regarded as two distinct books - the Kitab alLuma ("Book of Many-coloured Flower-beds") and the Kitab alusul ("Book of Roots").
Next, as all investigation proceeds from that which is known best to that which is unknown or less well known, and as, in social states, it is the collective phenomenon that is more easy of access to the observer than its parts, therefore we must consider and pursue all the elements of a given social state together and in common.
However crude and hasty this critical investigation, it helped to direct philosophic reflection to the unity of mind, and so to develop the post-Kantian line of speculation.
If the calculation be carried farther backas has been done by the seismic disaster investigation committee of Japan, a body of scientists constantly engaged in studying these phenomena under government auspices,it is found that, since the countrys history began to be written in the 8th century AD,, there have been 2006 major disturbances; but inasmuch as 1489 of these occurred before the beginning of the Tokugawa administration (early in the 17th century, and therefore in an era when methods of recording were comparatively defective), exact details are naturally lacking.
This special feature has been attributed to the Japanese habit of kneeling instead of sitting, but investigation shows that it is equally marked in the working classes who pass most of their time standing.

But when a committee of the Royal Asiatic Society, with George Grote at its head, decided that the translations of an Assyrian text made independently by the scholars just named were at once perfectly intelligible and closely in accord with one another, scepticism was silenced, and the new science was admitted to have made good its claims. Naturally the early investigators did not fathom all the niceties of the language, and the work of grammatical investigation has gone on continuously under the auspices of a constantly growing band of workers.
The labour devoted to an investigation is with Hallam no excuse for dwelling on the result, unless that is in itself important.
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.
Morley determined the densities of hydrogen and oxygen in the course of his classical investigation of the composition of water.
Here we can only summarize the points of the investigation.
There is only one practical published investigation of Airy's micrometer that is worthy of mention, viz.
His investigation tends to show that in the course of tradition cosmological myths are transformed into eschatological dogmas.
The efforts of individual scientific workers cannot as a rule produce such results in oceanography as in other sciences, but exceptions are found in the very special services rendered by the prince of Monaco, who founded the Oceanographical Institute in Paris and the Oceanographical Museum in Monaco; and by Professor Alexander Agassiz in the investigation of the Pacific.
Greater depths These preliminary trips of scientific marine investigation were than those usually sounded by a hand-line may possibly not have followed by the greatest purely scientific expedition ever underbeen beyond the reach of the earlier navigators, for Strabo taken, the voyage of H.M.S.
A closer investigation of the numerous long, narrow banks which lie off the Flemish coast and the Thames estuary shows that they are composed of fragments of rock abraded and transported by tidal currents and storms in the same way that the chalk and limestone worn off from the eastern continuation of the island of Heligoland during the last two centuries has been reduced to the coarse gravel of the off-lying Dune.
The whole subject still requires investigation.
Sorensen and Martin Knudsen after a careful investigation decided to abandon the old definition of salinity as the sum of all the dissolved solids in sea-water and to substitute for it the weight of the dissolved solids in 1000 parts by weight of sea-water on the assumption that all the bromine is replaced by its equivalent of chlorine, all the carbonate converted into oxide and the organic matter burnt.
Sorensen, carried out a careful investigation of the relation between the amount of chlorine, the total salinity and the specific gravity of sea-water of different strengths including an entirely new determination of the thermal expansion of sea-water.
The differences of salinity support this method, and, especially in the northern European seas, often prove a sharper criterion of the boundaries than temperature itself; this is especially the case at the entrance to the Baltic. Evidence drawn from drift-wood, wrecks or special drift bottles is less distinct but still interesting and often useful; this method of investigation includes the use of icebergs as indicators of the trend of currents and also of plankton, the minute swimming or drifting organisms so abundant at the surface of the sea.
Reports of many minor expeditions and researches have appeared in the Reports of the Fishery Board for Scotland; the Marine Biological Association at Plymouth; the Kiel Commission for the Investigation of the Baltic; the Berlin Institut fur Meereskunde; the bluebooks of the Hydrographic Department; the various official reports to the British, German, Russian, Finnish, Norwegian, Swedish, Danish, Belgian and Dutch governments on the respective work of these countries in connexion with the international cooperation in the North Sea; the Bulletin du musee oceanographique de Monaco (1903 seq.); the Scottish Geographical Magazine; the Geographical Journal; Petermanns Mitteilungen; Wagner's Geogi'aphisches Jahrbuch; the Proceedings and Transactions of the Royal Societies of London and Edinburgh; the Annalen der Hydrographie; and the publications of the Swedish Academy of Sciences.

A critical investigation of the conditions under which religious belief was possible was still wanting.
The direct result of this investigation is not known, but it is impossible to disconnect from it the promulgation by Pope Alexander V., on the 20th of December 1409, of a bull which ordered the abjuration of all Wycliffite heresies and the surrender of all his books, while at the same time - a measure specially levelled at the pulpit of Bethlehem chapel - all preaching was prohibited except in localities which had been by long usage set apart for that use.
He modestly entitled his work a Gnomon or index, his object being rather to guide the reader to ascertain the meaning for himself, than to save him from the trouble of personal investigation.
Subsequent psycho-physical investigations have all been in the spirit of his work; and although he consistently advocated the introspective method in psychological investigation, he was among the first to appreciate the help that may be given to it by animal and social and infant psychology.
The king of Prussia had some reason to complain of the sudden desertion of his ally, but there is no evidence whatever to substantiate his accusation that Bute had endeavoured to divert the tsar later from his alliance with Prussia, or that he had treacherously in his negotiations with Vienna held out to that court hopes of territorial compensation in Silesia as the price of the abandonment of France; while the charge brought against Bute in 1765 of having taken bribes to conclude the peace, subsequently after investigation pronounced frivolous by parliament, may safely be ignored.
This subject he was led to study by the experience of a colliery engineman, who noticed that he received a sharp shock on exposing one hand to a jet of steam issuing from a boiler with which his other hand was in contact, and the inquiry was followed by the invention of the "hydro-electric" machine, a powerful generator of electricity, which was thought worthy of careful investigation by Faraday.
The religion of the American aborigines, so far as it can be made a subject of investigation, consisted (1) in what the tribes believed.
Thus a reforming movement became heresy through disobedience to authority, and after being condemned embarked on a course of polemical investigation how to justify its own position.
The treatment of an angle as generated by rotation, the investigation of the relations between trigonometrical ratios and circular measure, the application of interpolation to trigonometrical tables, and the general use of graphical methods to represent continuous variation, all imply an analytical onlook, and must therefore be deferred to this stage.

The work was in fact the first attempt to substitute for the popular representations of Thiers and Lamartine the critical investigation which has been carried on with such brilliance by Taine and Sorel.
We can only conclude that it depends on wave form, a conclusion fully borne out by investigation.
If, however, we put on external forces of the required type X it is obvious that any wave can be propagated with any velocity, and our investigation shows that when U has the value in (6) then and only then X is zero everywhere, and the wave will be propagated with that velocity when once set going.
This investigation is obviously not exact, for it assumes that the form is unchanged, i.e.
Another important result of the investigation was that the phase of vibration of the fork was not altered by bowing it, the amplitude alone changing.
As a preliminary to the investigation of the modes of vibration of certain sources of sound we shall consider the formation of " stationary waves."
We might make this investigation more general by introducing a force X as in the investigation for air, but it hardly appears necessary.
This investigation is subject to the limitation that the diameter of the cross-section must be small compared with the wave-length.
But our investigation entirely leaves this out of account, and is therefore faulty.
Helmholtz's double siren is well calculated for the investigation of the laws of interference of sound.
The conditions assumed in this investigation are probably nearly realized in a harmonium and in a double siren of the form used by Helmholtz, and in these cases there can be no doubt that actual objective tones are produced, for they may be detected by the aid of resonators of the frequency of the tone sought for.
While he was criticized by the friends of Civil Service Reform for not going far enough during his presidency to protect the encroachments of those who desire to have the offices distributed as political rewards or for partisan ends, such specific acts as his transference to the classified service of all fourth-class postmasters east of the Mississippi and north of the Ohio rivers, his insistence upon a thorough investigation of the scandals in the Post Office department, and his order forbidding federal employes to use their offices for political purposes in the campaign of 1908 are typical of his vigorous support of the merit system.

In width of view, thoroughness of investigation and honesty of purpose he is unsurpassed by any historian.
The convection of a medium thus polarized involves electric disturbance, and therefore must contribute to the true electric current; the determination of this constituent of the current is the most delicate point in the investigation.
It is implied, moreover, that this doubt is not merely a stage in the road to true knowledge, but rather the last result of investigation, the conclusion that truth or real knowledge is unattainable by man.
The differences asserted by later writers are not borne out on investigation.

He also devoted much attention to the study of obscure morbid conditions like hysteria, especially in relation to hypnotism; indeed, it is in connexion with his investigation into the phenomena and results of the latter that his name is popularly known.
These functions are named after Friedrich Wilhelm Bessel, who in 1817 introduced them in an investigation on Kepler's Problem.
In 1764 Leonhard Euler employed the functions of both zero and integral orders in an analysis into the vibrations of a stretched membrane; an investigation which has been considerably developed by Lord Rayleigh, who has also shown (1878) that Bessel's functions are particular cases of Laplace's functions.

Hutton's suggestions are all the more to be regretted as they occur as a history which is the result of a good deal of investigation and which for years was referred to as an authority by many writers.
Palaeontology both borrows from and sheds light upon geology and other branches of the physical history of the earth, each of which, such as palaeogeography or palaeometeorology, is the more fascinating because of the large element of the unknown, the need for constructive imagination, the appeal to other branches of biological and physical investigation for supplementary evidence, and the necessity of constant comparison with the present aspects of nature.
The concurrence of botanical (Hooker, 1847), zoological, and finally of palaeontological evidence for the reconstruction of the continent of Antarctica, is one of the greatest triumphs of biological investigation.
An investigation by the U.S. Geological Survey in 1909 finds that the crude Mexican oils are of low grade, but that while not equal to those found in the upper Mississippi basin for refining purposes, they furnish an excellent fuel for railway engines and other industrial purposes.

This method was employed by Sir Isaac Newton, whose experiments constitute the earliest systematic investigation of the phenomenon.
Christiansen found, in an investigation of this kind, that the refractivity of the liquid could only be got to match that of the powder for mono-chromatic light, and that, if white light were used, brilliant colour effects were obtained, which varied in a remarkable manner when small changes occurred in the refractive index of the liquid.
Physically incapable of rising to passionate heights of oratory, Cotta's successes were chiefly due to his searching investigation of facts; he kept strictly to the essentials of the case and avoided all irrelevant digressions.
His investigation of the Saturnian system was crowned by the Royal Astronomical Society of London in 1903.
From the time of his first introduction to Tycho he had devoted himself to the investigation of the orbit of Mars, which, on account of its relatively large eccentricity, had always been especially recalcitrant to theory, and the results appeared in Astronomia nova ainoXayrgrii, seu Physica coelestis tradita commentariis de motibus stellae Martis (Prague, 1609).
The storm of protest of the other religious denominations caused the colonial office to undertake an investigation of the whole question, the result of which was presented in the report of 1828.
It does not follow, however, that a custom which has ceased to exist is of necessity forbidden, nor even that what was rejected by the authorities of the English Church in the 16th century is so explicitly forbidden as to be unlawful under its existing system; and not a few facts have to be taken into account in any investigation of the question.
Again, in several cases he ventured to question the correctness of the "accepted atomic weights," on the ground that they did not correspond with the Periodic Law, and here also he was justified by subsequent investigation.

It should, however, be here observed, that whoever takes a reading without investigation, on the authority either of a manuscript or of a great scholar, or of a number of scholars, ceases for the time being to be a textual critic.
Moreover, it is clear that Aristotle addressed himself to readers as well as hearers, as in concluding his whole theory of syllogisms he says, " There would remain for all of you or for our hearers (763,7 co y uµWV rt T&?v ipcpoapEVwv) a duty of according to the defects of the investigation consideration, to its discoveries much gratitude " (Sophistical Elenchi, 34, 184 b 6).
In order to refer back to the Physics, the De Coelo, and the De Generatione, this work begins by stating that the first causes of all nature and all natural motion, the stars ordered according to celestial motion and the bodily elements with their transmutations, and generation and corruption have all been discussed; and by adding that there remains to complete this investigation, what previous investigators called meteorology.
Then follows the treatment of oligarchy, democracy, commonwealth and tyranny, and of the various powers of government (0), and independent investigation of revolution, and of the means of preserving states (E), and a further treatment of democracy and oligarchy, and of the different offices of the state (Z), and finally a return to the discussion of the right form of constitution (II, 0).
But two corollaries follow from our present investigation of his extant writings; the first, that it was the long continuance of the Peripatetic school which gradually caused the publication, and in some cases the forgery, of the separate writings; and the second, that his Peripatetic successors arranged and edited some of Aristotle's writings, and gradually arrived by the time of Andronicus, the eleventh from Aristotle, at an order of the whole body of writings forming the system.
Aristotle was the founder of Logic; because, though others, and especially Plato, had made occasional remarks about reason (X yos), Aristotle was the first to conceive it as a definite subject of investigation.
Aristotle, who made this great discovery, must have had great difficulty in developing the new investigation of reasoning processes out of dialectic, rhetoric, poetics, grammar, metaphysics, mathematics, physics and ethics; and in disengaging it from other kinds of learning.
But the general discussion of opinions, signified by both words, is only a subordinate part of Aristotle's profound investigation of the whole process of reasoning.
On the other hand, it does not follow that Aristotle would have regarded the Topics, which he calls " the investigation " and " the investigation of dialectic " (7) Jrpayyareta, Top, i.
They contain however many relics of dialectic. The Rhetoric is declared by him to be partly dialectic. The Topics is at least an investigation of dialectic, which has had an immense influence on the method of argument.
His first important astronomical work was a careful investigation of the libration of the moon (Kosmographische Nachrichten, Nuremberg, 1750), and his chart of the full moon (published in 1775) was unsurpassed for half a century.
In September 1908, after an investigation which showed that many wardens had been in the pay of convict lessees and that terrible cruelty had been practised in convict camps, an extra session of the legislature practically put an end to the convict lease or contract system; the act then passed provided that after the 31st of March 1909, the date of expiration of leases in force, no convicts may be leased for more than twelve months and none may be leased at all unless there are enough convicts to supply all demands for convict labour on roads made by counties, each county to receive its pro rata share on a population basis, and to satisfy all demands made by municipalities which thus secure labour for $100 per annum (per man) paid into the state treasury, and all demands made by the state prison farm and factory established by this law.
The necessity and universality of the judgments of causality and substantiality are taken for granted; and there is no investigation of the place held by these notions in the mental constitution.

In 1865 Pasteur undertook a Government commission for the investigation of the malady.
Fourthly, the convention recommends that in disputes of an international nature, involving neither national honour nor vital interests, and arising from a difference of opinion on points of fact, the parties who have not been able to come to an agreement by means of diplomacy should institute an international commission of inquiry to facilitate a solution of these disputes by an investigation of the facts.
The extension of the investigation to wide slits was first made by the present writer in the article " Spectroscopy " in the 9th edition of the Encyclopaedia Britannica.
Bolometric methods may be used with facility and advantage in the investigation of the distribution of intensities in continuous or semi-continuous spectra but difficulties are met with in the case of line spectra.
For the investigation of the spectra of gases at reduced pressures the so-called Plucker tubes (more generally but incorrectly called Geissler tubes) are in common use.
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.
We might probably with advantage find some definition of what may be called " radiation temperature " based on the relation between radiation and absorption in Kirchhoff's sense, but further information based on experimental investigation is required.
Two methods of investigation are available.
Experimentally we should be confined to a strict investigation of absorption spectra, because in the electric discharge temperature has no definite meaning, and variations of pressure and density are not easily measured.
He concludes an interesting and important investigation by' giving reasons for believing that the centre of a widened line radiates with smaller energy than the adjacent parts.
The subject wants further investigation, especially with a view to deciding the connexion between the molecular rush and the discharge.
The subject, however, required further experimental investigation, which was supplied by Paschen.
Nevertheless, the subject is well worth further investigation.
Previous to Stark's investigation P. Lenard 2 had concluded that the carriers of certain of the lines of the flame spectra of the alkali metals are positively charged.
Wood remarks, the careful investigation of these phenomena is.
Kundt,' who initiated this line of investigation, came to the conclusion that the absorption spectra of certain organic substances like cyanin and fuchsin were displaced towards the red by the solvent, and that the displacement was the greater the greater the dispersive power of the solvent.
Whilst at Rome he issued several bulls to the archbishop of Canterbury, the king of England, and the university of Oxford, commanding an investigation of Wycliffe's doctrines.
It was first isolated in 1803 and was the subject of an important investigation by v.Liebig in 1837 (Annalen,1837,22, p.1).

This fact will most likely prove exceedingly fertile, and of great value in the investigation of the conditions of natural force."
We have given a few examples of the concentration of his efforts in seeking to identify the apparently different forces of nature, of his far-sightedness in selecting subjects for investigation, of his persistence in the pursuit of what he set before him, of his energy in working out the results of his discoveries, and of the accuracy and completeness with which he made his final statement of the laws of the phenomenon.
He developed a great research laboratory of experimental physics, attracting numerous workers from many countries and colonies; advances were made in the investigation of the conduction of electricity through gases, in the determination of the charge and mass of the electron and in the development of analysis by means of positive rays.
But Huygens's most important contribution to the subject was his investigation, published in 1673, of the motion of a rigid pendulum of any form.
This is the earliest example of a theoretical investigation of the rotation of rigid bodies.
Some years later he succeeded in showing that Kepler's elliptic orbit for planetary motion agreed with the assumed law of attraction; he also completed the co-ordination with terrestrial gravity by his investigation of the attractions of homogeneous spherical bodies.
The distinguishing feature of these explorations, led by Russian officers, is their high scientific value and the contributions they have offered to the botany, natural history, geology and meteorology of the regions under investigation in addition to the actual geographical data attained.
In this way two temperature points are obtained in the investigation - the higher giving a point on the equilibrium curve, the lower showing the non-variant point.
Experiments on alloys are, in some ways, easier to make than on pairs of non-metallic substances, partly owing to the possibility of polishing sections for microscopic examination, and the investigation of alloys has done much to elucidate the general phenomena of solution, of which metallic solution constitutes a special case.
But another method of investigation will illustrate new ways of treating our subject.
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.
In all this investigation it should be noted that the heat of solution with which we are concerned is the heat effect when solid dissolves to form a saturated solution.
The physical investigation of osmotic pressure, and its correlation by Van't Hoff with the pressure of a gas, brought forward a new aspect of the phenomena, and suggested an identity of physical modus operandi as well as of numerical value.
At one time sea-water was thought to be injurious, but modern investigation finds no objection to it except on the score of appearance, efflorescence being more likely to occur when it is used.
Few branches of science, so important on their bearings on every-day life and so difficult of investigation, can be said to have been created and raised at once to a state of high advancement by the labours of a single man.
The genuineness of these so-called translations from the works of a 3rd-century bard was immediately challenged in England, and Dr Johnson, after some local investigation, asserted (Journey to the Western Islands of Scotland, 1775) that Macpherson had only found fragments of ancient poems and stories, which he had woven into a romance of his own composition.
No adequate investigation of this subject has yet been made, but some observations made by the author of this article, on the piebald black and white rat, show that differences connected with the microscopic structure exist.
He had neither the temperament for original investigation, nor the leisure necessary for the purpose.
Most of the recent research on Pliny has been concentrated on the investigation of his authorities, especially those which he followed in his chapters on the history of art - the only ancient account of that subject which has survived.
