"Hemispherical" Quotes from Famous Books



... expansion, commonly called the Minie principle, in 1836.'' The Minie bullet contained an iron cup in a cavity in the base of the bullet. The form of the bullet was subsequently changed from conoidal to cylindro-conoidal, with a hemispherical iron cup. This bullet was used in the Enfield rifle introduced into the British army in 1855. It weighed 530 grs., and was made up into cartridges and lubricated as for the Minie rifle. A boxwood plug to the bullet was also used. The bullet used in the breech-loading Martini-Henry ...

... ax-gun, an affair not unlike the battle-ax of the Middle Ages. It was about three feet long. The shaft consisted of a rocket gun, with an ax-blade near the muzzle, and a spike at the other end. It was a terrible weapon. Jointed leg-guards protected the ax-gunner below the rim of his shield, and a hemispherical helmet, the front section of which was of transparent ultron reaching down to the ...

... Dunsink Observatory for the equatorial telescope, the object-glass of which was presented to the Board of Trinity College, Dublin, by the late Sir James South. The main part of the building is a cylindrical wall, on the top of which reposes a hemispherical roof. In this roof is a shutter, which can be opened so as to allow the telescope in the interior to obtain a view of the heavens. The dome is capable of revolving so that the opening may be turned towards that part of the sky where ...

... the following series of shapes, which shows a pretty full graduation of outline from extreme to extreme. Beginning with the simplest fundamental form, the shallow cup (Fig. 45, a), we ascend gradually to more complex outlines, such as are seen in the hemispherical bowl (b), the deep basin with slightly incurved rim (c), the globular form (d), and the elongated form (e). Occasionally we see an eccentric variation, such as is shown in f. Flat bottoms ...

... disease from smallpox, but in certain patients it is very difficult. The chief points in the differential diagnosis are as follows. (1) In chicken-pox the rash is distributed chiefly on the trunk, and less on the limbs. (2) Some of the vesicles are oval, whereas in smallpox they are always hemispherical. They are also more superficial, and have not at the outset the hard shotty feeling of the more virulent disease. (3) The vesicles attain their full growth within twelve to twenty-four hours. (4) The pustules are usually monocular. (5) ...

... nucleus. The nucleus soon enlarges (fig. 80) and a large dense body (n) appears which stains like chromatin with various staining media. A little later (fig. 81) the chromatin forms a homogeneous, more or less hemispherical or sometimes crescent-shaped mass which stains an even gray in iron-haematoxylin. In addition the nucleus contains a body (n) smaller than in the preceding stage, but staining the same. As the nucleus condenses and ...

... too, over the communion table was intended only to serve till something more worthy could be prepared; and, to supply its place, Wren had modelled a magnificent altar, consisting of four pillars wreathed of the finest Greek marbles, supporting a hemispherical canopy, richly decorated with sculpture. But marble, such as he liked, could not readily be procured: dissensions arose, and the work remained in the models. The interposition of the Duke of York—the malevolence ...

... bringer of grapes and barley sheaves. But his most familiar form is the bearded and thick-set mountaineer, armed with a ponderous thunder hammer, a flashing trident, and a long two-edged sword with a hemispherical knob on the hilt, which dangles from his belt, while an antelope or goat wearing a pointed tiara prances beside him. This deity is identical with bluff, impetuous Thor of northern Europe, Indra ...

... We also found quantities of honey. Honey-birds were numerous, and ever ready to oblige by pointing out a bees' nest. The scenery, was very beautiful. To the north-west towered some of the loftiest peaks of the Drakensberg. The bare, granite domes around us were almost hemispherical in shape. They arose out of swamp rooted forest. The ...

... auditors. Conspicuous above everything else in the city, as gold is conspicuous from dross, is the golden dome and gold-tipped minarets of the holy edifice that imparts to the city its sacred character. The gold is in thin plates covering the hemispherical roof like sheets of tin; like most Eastern things, its appearance is more impressive from a distance than at close quarters. Grains of barley deposited on the roof by pigeons have sprouted and grown in rank bunches between the thin gold plates, many of which are partially loose, imparting ...

... Mr. Alley, probably from the Mason, by years of high cultivation and careful selection of seed stock. I introduced this cabbage and the Stone Mason to the general public many years ago, and it has been pretty thoroughly disseminated throughout the United States. Heads varying in shape between hemispherical and spherical, with but few waste leaves surrounding them; size very large, varying from fifteen to twenty inches in diameter, and, in some specimens, they have grown to the extraordinary dimensions of twenty-four inches. In good soil, and with the highest culture, this ...

... pressure, and united together. This will represent the blastoderm. Now with the finger, thrust in one side of the ball until it touches the other: so making a cup. This action will stand for the process of invagination. Imagine that by continuance of it, the hemispherical cup becomes very much deepened and the opening narrowed, until the cup becomes a sac, of which the introverted wall is everywhere in contact with the outer wall. This will represent the two-layered ...

... enormous mountains, some twenty miles apart from peak to peak, and remarkable for their exceptional height—which I estimated at fully fourteen thousand feet—as well as from the fact that they were identical not only in shape, but also apparently in size and altitude. In shape they were almost hemispherical, and to add to their similarity each bore on its very summit a protuberance very much resembling in appearance a beehive-shaped Kafir hut, but much larger, being probably quite two hundred feet in height. The tops of these remarkable mountains were covered with snow ...

... it was not satisfactory in anything but calm weather. Accordingly scientific initiative was stimulated with a view to the evolution of a superior vessel. These endeavours culminated in the Parseval-Siegsfeld captive balloon, which has a quaint appearance. It has the form of a bulky cylinder with hemispherical extremities. At one end of the balloon there is a surrounding outer bag, reminiscent of a cancerous growth. The lower end of this is open. This attachment serves the purpose of a ballonet. The wind blowing against ...

... this little bird begin to form her nest, about the middle of May: which consists, like that of the house-martin, of a crust or shell composed of dirt or mud, mixt with short pieces of straw to render it tough and permanent; with this difference, that whereas the shell of the martin is nearly hemispheric, that of the swallow is open at the top, and like half a deep ditch; this nest is lined with fine grasses, and feathers which are often collected as they float in ...

... mud-walls (informed at first, perhaps, by this little bird), raise but a moderate layer at a time, and then desist, lest the work should become top-heavy, and so be ruined by its own weight. By this method in about ten or twelve days is formed a hemispheric nest with a small aperture towards the top, strong, compact, and warm; and perfectly fitted for all the purposes for which it was intended. But then nothing is more common than for the house-sparrow, as soon as the shell is finished, to seize on it as its own, to eject ...

The material is a framework of "Digo," or sticks bent and hardened in the fire: to ...

... chalets where the herdsmen dwelt. None of the mountains seemed so bare and sterile as Mount Washington, and though they were on a sensibly vaster scale than the White Mountains generally, I remembered the grandeur of Chocorua and Kearsarge in their presence. But my national—not to say my hemispheric—pride suffered a terrible blow as the season advanced. I had bragged all my life of the glories of our American autumnal foliage, which I had, in common with the rest of my countrymen, complacently denied to all the rest of the world. Yet here, before my very eyes, the same beautiful ...
