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.

To these must be added his elaborate treatise on Shipbuilding, Theoretical and Practical.

This survey of the existing developments of pure mathematics confirms the conclusions arrived at from the previous survey of the 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 value of this injunction may have been, however, in practice the use of the pastoral staff was discontinued until its gradual revival in the last decades of the 19th century.

The theoretical element is the ratio of the parallactic inequality to the solar parallax.

Ampere's experimental and theoretical investigation of the mutual action of electric currents, and of the equivalence of a closed circuit to a polar magnet, the latter suggesting his celebrated hypothesis that molecular currents were the cause of magnetism.

Although arbitrations proper may be thus distinguished from " mixed commissions," it must not be supposed that any hard or fast theoretical line can be drawn between them.

Within this broad division, however, have appeared from time to time political groups in bewildering variety, each adopting a party designation according to the exigencies of the moment, but each basing its programme on one or other of the theoretical foundations above mentioned.

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.

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.
