"Concavity" Quotes from Famous Books
 ... at its first dramatic appearance, was one of the most astonishing things that we saw in the whole course of our adventures. It was not a cerulean vault like that which covers the earth in halcyon weather, but an indescribably soft, pinkish-gray concavity that seemed nearer than the sky and yet farther than the clouds. Here and there, far beneath it, but still at a vast elevation, floated delicate gauzy curtains, tinted like sheets of mother-of-pearl. The sun was no longer visible, ...

... side, the axillary space does not (properly speaking) exist; and in this position, the axillary vessels and nerves make a general curve from the clavicle at the point K, Plate 14, to the inner side of the arm, the concavity of the curve being turned towards the thoracic side. But when the arm is abducted from the side, and elevated, the vessels which are destined to supply the limb follow it, and in this position they take, in reality, a serpentine course; the first curve of ...

... rapidly with approach to the banks or with shallowing of the depth, very rapidly close to the banks, and was very small at the edges, possibly zero. The figure of the curve was found to be determined by the figure of the bed, a convexity in the bed producing a concavity in the curve and vice versa, and more markedly in shallow than in deep water. Curves on the same transversal, at the same site, and with similar conditions, but differing in general velocity, were nearly parallel ...

... we stood in very slowly toward the shore. By sunset we could see the full outline of the coast of Kamchatka for a distance of fifty or sixty miles. The general coast line formed the concavity of a small arc of a circle. As it was too late to enter before dark, and we did not expect the light would be burning, we furled all our sails ...

... Those which I use measure 12x8" at the head, 8x6" at the foot of the tub. They are 1/4" thick. They are placed so as to have their long diameter correspond to the height of the tub. The bed which is to receive the carbon at the head of the tub must be deeper than 1/4" on account of the concavity of the back-rest. ...

... of interest to consider a common animal like the jellyfish Aurelia. It is admirably suited for a leisurely life in the open sea, where it swims about by contracting its saucer-shaped body, thus driving water out from its concavity. By means of millions of stinging cells on its four frilled lips and on its marginal tentacles it is able to paralyse and lasso minute crustaceans and the like, which it then wafts into its mouth. It has a very eventful life-history, for it has in its early youth ...

... notably different thickness would have been found there;"—though it does not appear why they were not thus calipered.[247] Further, externally, "all the sides" (says Professor Smyth) "were slightly hollow, excepting the east side;" and the "two external ends" also show some "concavity" in form. "The outside," (he avows) "of the vessel was found to be by no means so perfectly accurate as many would have expected, for the length was greater on one side than the other, and different also according ...

... length. The frame should be of light spruce, the same size as the cross-pieces. Care must be taken to have the angles right. When the frame is finished, cover loosely with manila paper, so that there will be some concavity on the face of the kite on each side below the cross-stick, so that it will belly like a sail; bind the edges with thin wire which stretches less than string. This kite will fly in a very light breeze. The string, ...

... Humboldt, who saw it, looking from the Silla de Caraccas over the Caribbean Sea. It gives you the impression of standing on the edge of the earth, and looking off into space. From the mast-head, the ocean appears either flat or slightly concave, and aeronauts declare that this apparent concavity becomes more marked, the higher they ascend. It is only at those rare periods when the air is so miraculously clear as to produce the effect of no air—rendering impossible the slightest optical illusion—that our eyes can see things as they really are. So pure was the atmosphere to-day, that, ...

... sea for their subsistence. This I judged from the very inferior state of their canoes which are very much less ingeniously formed than even the frail ones of the Port Jackson natives; being merely sheets of bark with the ends slightly gathered up to form a shallow concavity, in which they stand and propel them by means of poles. Their huts are more substantially constructed and more useful as dwellings than any to the southward, and will contain eight or ten persons; while those ...

... with its axis, and perfectly vertical. The keel (properly so called) is formed by the joining of the two vertical planes. The surface thus formed is a parabola whose apex is in front, the maximum ordinate behind, and the concavity directed toward the bottom of the water. The stern is a vertical plane intersecting at right angles the two lateral faces and the parabolic curve, which thus terminates in a sharp edge. The prow of the boat is connected with the apex of the parabola ...

... examined, various devices are employed in the construction of reflecting telescopes to avoid the loss of light which would result—a loss which would be important even with the largest mirrors yet constructed. Thus, in Gregory's Telescope, a small mirror, having its concavity towards the great one, is placed in the axis of the tube and forms an image which is viewed through an aperture in the middle of the great mirror. A similar plan is adopted in Cassegrain's Telescope, a small convex mirror replacing the concave one. In Newton's Telescope a small ...

Thereat Mr. Polly, emitting such words as everyone knows and nobody prints, butted his utmost into the concavity of Mr. Rusper, entwined a leg about him and after terrific moments of swaying instability, fell headlong beneath him amidst the bicycles and pails. There on the pavement these inexpert children of a pacific age, untrained in arms and uninured to violence, abandoned themselves to ...

It extended forward three or four feet, rudely sloping away like the forepiece of a cap, but the concavity below was less than half that depth. Jack expected to find a retreat ten or fifteen feet deep. As it was, there was barely room to screen themselves from the flying bullets, and had the rain been driven from the opposite direction when Otto first sought refuge there it would have given ...

... Japanese pillow is a little lacquered box with drawers in it, in which the ladies keep various small articles for their toilet—paper, hair-arrows, pins, etcetera. In the top of this curious box is a concavity with a little cushion wrapped in clean paper, and on this the back of the head is rested. Thus their head-dresses are not tumbled at night. The inhabitants of the Fiji Islands use a similar pillow for the same object of preventing their elaborately-dressed ...

... illumination of Mrs. Hatch's world could be described as dim: in actual fact, Lily found her seated in a blaze of electric light, impartially projected from various ornamental excrescences on a vast concavity of pink damask and gilding, from which she rose like Venus from her shell. The analogy was justified by the appearance of the lady, whose large-eyed prettiness had the fixity of something impaled and shown under glass. This did not preclude the immediate discovery that she ...

... every day. People think of the clouds as about as large as they look—forty yards over, perhaps; they see generally that they are solid bodies subject to the same laws as other solid bodies, roundish, whitish, and apparently suspended a great way under a high blue concavity. So that these ideas be tolerably given with smooth paint, they are content, and call it nature. How different it is from anything that nature ever did, or ever will do, I have endeavored to show; but I cannot, and do not, expect the contrast to be fully felt, unless the reader will actually go ...

The two species are not only distinct in certain peculiarities of form, but they differ in their habits. The Indian elephant dislikes the sun, and ...
