    He was attaché to Jerome's son, Prince Napoleon, during the Crimean War, and wrote a Précis historique des operations militaires en Orient, de mars 1854 a octobre 1855 (1857), which was completed many years later by a volume entitled La Crimee et Sebastopol de 1853 d 1856, documents intimes et inedits, followed by the complete list of the French officers killed or wounded in that war (1892).

    Hence to represent D, Greek has now to resort to the clumsy device of writing NT instead.

    151

    Hence, multiplying these normal forces by the areas of the corresponding faces, we have the total flux parallel to the x-axis given by - (d 2 V/dx 2)dxdydz, and similar expressions for the other sides.

    If 2R be the diameter of the objectglass and D the distance of the object, the angle subtended by AP is E/D, and the angular resolving power is given by X/2 D sin a = X/2 R (3) This method of derivation (substantially due to Helmholtz) makes it obvious that there is no essential difference of principle between the two cases, although the results are conveniently stated in different forms. In the case of the telescope we have to deal with a linear measure of aperture and an angular limit of resolution, whereas in the case of the microscope the limit of resolution is linear, and it is expressed in terms of angular aperture.

    The Platonic testimony, if it proved anything, would prove too much, namely, that the doctrine of the unity of Being originated, not with Xenophanes, but before him; and, in fact, the passage from the Sophist no more proves that Plato attributed to Xenophanes the philosophy of Parmenides than Theaetetus, 160 D, proves that Plato attributed to Homer the philosophy of Heraclitus.

    404

    The points A, B, C, D are termed " nodes," and the points half-way between them " loops."

    405

    The port has assumed first-class importance, mail steamers calling vL23 d regularly as well as men-of-war and the mercantile marine of all nations; and it is now one of the finest artificial harbours in the world.

    The pressure on the rollers is limited to about p= 600 d in lb per in.

    407

    The process begins with the formation of brilliant granules (A, B); these increase, and the brilliant substance gradually balls together (C) and forms the spores (D), one in each segment, which soon acquire a membrane and ripen (E).

    The rejection of this budget in December by the House of Lords led to d desperate struggle at the polls in January 1910, but the confident hopes of the Unionists were doomed to disappointment.

    413

    The resistance R can thus be divided into two factors, one of which is d 2, where d denotes the diameter of the shot in inches, and the other factor is denoted by p, where p is the resistance in pounds at the same velocity to a similar I-in.

    The sound was that of the unvoiced dental stop. The English t, however, is not dental but alveolar, being pronounced, as d also, not by putting the tongue against the teeth but against their sockets.

    422

    The sounds of t and d are more dental than in English, though they vary; the voiced spirants are very soft; the voiceless nasals are aspirated, thus is similar to Eng.

    423

    The speed-cones are either continuous cones or conoids, as A, B, whose velocity ratio can be varied gradually while they are in motion by shifting the belt, or sets of pulleys whose radii vary by steps, as C, D, in which case the velocity ratio can be changed by shifting the belt from one pair of pulleys to another.

    This makes it all the more remarkable that Beethoven's second and only important Mass (in D, Op. 123) is not only the most dramatic ever penned but is, perhaps, the last classical Mass that is thoughtfully based upon the liturgy, and is not a mere musical setting of what happens to be a liturgic text.

    459

    This may be accomplished by using a vessel with a somewhat wide bottom, and inserting the substance so that it may be volatilized very rapidly, as, for example, in tubes of Wood's alloy, D and by filling the tube with hydrogen.
