"Concavity" Quotes from Famous Books



... 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 to the southward are seldom large enough to hold three; they are arched over ...

... of sound leather, the convex side upwards and the concave downwards, was fitted into the recess turned out in the neck of the press-cylinder, at the place formerly used as a stuffing-box. Immediately on the high pressure water being turned on, it forced its way into the leathern concavity and 'flapped out' the bent edges of the collar; and, in so doing, caused the leather to apply itself to the surface of the rising ram with a degree of closeness and tightness so as to seal up the joint the closer ...

... in, though never quite up to the base of the cliff. Between this and the strand lies the elevated platform already spoken of, accessible from above by a sloping ravine, the bed of a stream running only when it rains. As said, it is only an acre or so in extent, and occupying the inner concavity of the semicircle. The beach is not visible from it, this concealed by the dry reef which runs across it as the chord of an arc. Only a small portion of it can be seen through the portal which admits the tidal flow. Beyond, stretches the open sea outside the ...

... region on which Miss Bart now found herself entering. It was, however, only figuratively that the 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 ...

... which must have been of different forms and sizes when the land stood at different levels: for if we look to the actual beach of a narrow creek, its slope is directed towards the middle; whereas, in an open bay, or slight concavity on a coast, the slope is towards the mouth, that is, almost directly seaward; hence as a bay alters in form and size, so will the direction of the inclination of its successive beaches ...

There we found one poor Soldier alive, who, upon his throwing in, had catch'd fast hold of some impending Bushes, and sav'd himself on a little Jutty within the Concavity.

... dropped low, a horse that at first glance appeared to be Don Quixote's Rosinante reincarnate, a gigantic "crow-bait" with a head as long and coarse as an eighteen-hand mule's, an under lip pendulous as a camel's dropping ears nearly long enough to brush flies off his nostrils, with such an ingrowing concavity of under jaw and convexity of face as would have enabled his head to supply the third of a nine-foot circle, a face curved as a scimitar and nearly as sharp. Both in shape and dimensions it was the grossest possible caricature of a Roman-nosed equine head the ...

... 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 ...

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 which is described, ...

... both from fate and fortune. She had been born ugly; with broad, flat face like unto the moon at full, or a dish. Her back was a little humped, her arms disproportionately long, losing in plumpness what they gained in extension. She seemed to have no breasts at all, the chest forming a concavity in correspondence to the convexity of the back, with a smoothness much like the inner surface of a bowl. This perhaps was no disadvantage—under the conditions. So much for fate. But fortune had been no kinder. "Blooming" into girlhood, she had been attacked by smallpox. Matazaemon ...

When she had proceeded about two or three yards, the passage opened into a concavity or apartment, high enough to permit her to sit at her ease, and of irregular, but narrow, dimensions.
