... figure 5F, i', which may be traced through twenty-five or thirty sections in this series. The epithelium of the stomach is fairly thick, and consists of five or six layers of compact, indistinctly outlined cells with spherical nuclei. Ventrad to the stomach is seen, in figure 5F, a section of the duodenum, i, which extends, with gradually diminishing caliber, for twenty-five or thirty sections caudad to the posterior limit of the stomach, where it opens to ...

... lay. Our telescope was a refractor and had an objective of two feet diameter. It was firmly supported on a trap rock pedestal. The eye piece adjustment was unusually successful, and the remarkable freedom of the objective from any traces of spherical or chromatic aberration gave us an image of surprising clearness. The photographic results were admirable. I imagine few more satisfactory photographs of the face of Moon have been made than those we secured, so far at least as definition is ...

... things they agree with the Greeks, for they affirm that the world was produced, and is perishable, and that it is spherical; that God, governing it as well as framing it, pervades the whole; that the principles of all things are various, but water is the principle of the construction of the world; that besides the four elements there is a fifth, nature—whence heaven and the stars; ...

... mocker of the Homeric deceit because he had scoffed at the deceit in Homer. Xenophanes also dogmatised, contrary to the assumptions 225 of other men, that all things are one, and that God is grown together with all things, that He is spherical, insensible, unchangeable, and reasonable, whence the difference of Xenophanes from us is easily proved. In short, from what has been said, it is evident that although Plato expresses doubt about some things, so long as he has ...

... the feathers in her hat, the high collar of her jacket make more significant the fact that her lines are not artistic and that her face is unbeautifully round. She can enhance her charms and apparently decrease the too spherical cut of her countenance by adopting the mode illustrated in No. 27. The angular bows on the hat, the geometric lines of the broad hat-brim, the precise cut of the lapels on the corsage, the neat throat-band and V-shaped vesture—all ...

... which he lived than beneficial to posterity. This design was to sail to India by taking a western direction. By the accounts of travellers who had visited that part of Asia, it seemed almost without limits on the east; and by attending to the spherical figure of the earth Columbus drew the natural conclusion, that the Atlantic ocean must be bounded on the west either by India itself, or by some continent not far distant ...

... the world. That the world is very resplendent is made perspicuous from the figure, the color, the magnitude of it, and likewise from the wonderful variety of those stars which adorn this world. The world is spherical; the orbicular hath the pre-eminence above all other figures, for being round itself it hath its parts like itself. (On this account, according to Plato, the understanding, which is the most sacred part of man, is ...

... other species in India being F. charltoni. The genus is peculiar from the resemblance of the nasal bones to those of the lynx, and from the complete or nearly complete bony orbit; the skull differs, however, greatly from the viverriceps form, being much more spherical with very short nasal bones. There is an admirable illustration in De Blainville's 'Osteographie' of it under the name of F. longicaudata. Very little is known as yet of ...

... the remover of pain[270]—has many marvellous and beneficial properties, for the sake of which the buildings round it ought to be kept in good repair. One may see it welling up from the bowels of the earth in spherical form, under a canopy of steam. From this parent spring the waters, glassy-clear and having lost their first impetuosity, flow by various channels into chambers prepared for them by nature but made longer by art. In the first, when the boiling element dashes against the rock, it is hot enough ...

In the center of the table, between the periwinkles, was another gift from Tio Ventolera, a terra cotta female head with a strange round tiara crowning her braided hair.

As Jaime gazed at this companion of his solitude his imagination pierced the harsh outer crust and he recognized the serenity of feature, the strangeness and ...

... was done secretly. The land is so low in the vicinity of Alexandria that boats or galleys are out of sight from it at a very short distance from the shore. In fact, travelers say that, in coming upon the coast, the illusion produced by the spherical form of the surface of the water and the low and level character of the coast is such that one seems actually to descend from the sea to the land. Caesar might therefore have easily kept his expedition a secret, had it not been that, in order to be provided with ...

... reader of the works of Archimedes will say that there can be no true levelling by means of water, because he holds that water has not a level surface, but is of a spherical form, having its centre at the centre of the earth. Still, whether water is plane or spherical, it necessarily follows that when the straightedge is level, it will support the water evenly at its extremities on the right and left, but that if ...

Figure 21, not only well-rounded Tertiary pebbles, but great blocks of hard sandstone, of the kind called in the south of England "greywethers," some of which are 3 or 4 feet and upwards in diameter. They are usually angular, and when spherical owe their shape generally to an original concretionary structure, and not to trituration in a river's bed. These large fragments of stone abound both in the higher and lower level gravels round Amiens and at the higher level at Abbeville. They have also been traced ...

... secret downwards between inner walls of the house, penetrating everywhere. One went down to a boiler behind the kitchen-range and filled it, and as the fire that was roasting the joint heated the boiler, the water mounted again magically to the cistern-room and filled another cistern, spherical and sealed, and thence descended, on a third journeying, to the bath and to the lavatory basin in the bathroom. All this was marvellous to Edwin; it was romantic. What! A room solely for baths! And a huge painted zinc bath! Edwin had never ...

In other cases the casts are rendered opaque by entangled earthy granules (carbonate of lime), or crystals of some other ...

... far the earliest steps in the development of the ovum. One portion, we observed, was promptly set apart for the construction of the future child; this favored portion became inclosed by all the rest of the ovum, which has a more or less spherical form and is technically called the fetal sac. The first duty of the sac is to take root in the womb, and the second, no less vital, is to draw nourishment from the mother. But neither of these functions can be performed without the participation of the uterine mucous membrane, the soil, as it were, ...

The sphere alone appears to fulfil this condition, and Professor Copeland therefore suggests that the material constituting the surface of the streak must be made up of a large number of more or less completely spherical globules.

They should be achromatic, and the utmost transparency should be obtained; and under the closest inspection of the glass not the slightest wavy appearance, or dark spot should be detected; and a curvature which as much as possible prevents spherical aberration should be secured.

The first was, that as a general rule, the larger the bodies were, the more rapid their descent; the second, that, between two masses of equal extent, the one spherical, and the other of any other shape, the superiority in speed of descent was with the sphere; the third, that, between two masses of equal size, the one cylindrical, and the other of any other shape, the cylinder was absorbed the more slowly. ...

... qualities of things, or reproduce them exactly. The Ptolemaic system, for instance, was perfectly scientific; it was based on careful and prolonged observation and on just reasoning; but it was modelled on an image—the spherical blue dome of the heavens—proper only to an observer on the earth, and not transferable to a universe which is diffuse, centreless, fluid, and perhaps infinite. When the imagination, for any reason, comes to be peopled with images of the latter ...

By this it is made clear that the shadow is not produced by the angle of the derived shadow but only by the body casting the shadow; &c.

And this is proved by what was said before, which is: That a shadow will ...
