... great scene which appeared to stretch away into the distance for several miles, including the trees, brook, lake, sun, clouds, sky, and everything else, was painted on the wall, ceiling and floor, of a circular room. The ceiling was arranged in the shape of a dome, while the floor made a concave connection with the wall. The whole apartment could not have been over fifty feet in diameter. The entire room was covered by one painting, and so well had the work been done that the only way I could discern the difference between the real and artistic scene was by extending my hands ...

... straight for the period and too thick, nearly met above the short, tip-tilted nose, freckled as a plover's egg, and that at a time when no well brought-up damsel ventured forth in the sun's rays without veil or parasol. Her face was deficient in modelling, being one of those subtly concave faces not without a fascination of their own, with an egg-like curve of prominent delicately-square chin. Her mouth, too large, opened very beautifully when she laughed over square thickly-white teeth. Her eyes were small and of no particular colour, ...

... restful, meditative, a place where the feeling of magical allure takes a deeper, more subjective character. It might well be called the Court of Pools, for two, quiet pools, one circular, one oblong except for its concave side to hold the other, fill the floor of its sunken garden and reflect its pensive as well as its physical charms. The Caryatids repeated throughout this court are the joint work of John Bateman and A. Stirling Calder. They inject into the court its fairy spirit without ...

One enters the glade coming up the river bottom along the base of the bluff; the other debouches at the opposite ...

Some time afterward the end of the intestine descended several inches and hung loosely on the concave surface of the rectum. A sponge was introduced to support the rectum and prevent access of air. The destruction of the parts was so complete and the opening so large as to bring into view the whole inner surface of the pelvis, in spite of which, after prolonged suppuration, the wound ...

Shells, pink and pearly, brown and lilac, scarlet and cobalt, strew the flower-decked floor with infinite variety, concave and spiral, ribbed and fluted, fretted and jagged—the satin smoothness of convoluted forms lying amid rugged shapes bristling with spines and needles.

War Paint and Blondie had tied up their horses outside; but the other officers had stormed in brutally, horses and all. Embroidered hats with enormous and concave brims bobbed up and down everywhere.

Over the infernal din of the drunkards, the heavy breathing of the horses, the stamp ...

Behind me were furze bushes dried by the heat; immediately in front dropped the steep descent of the bowl-like hollow which received and brought up to me the ...

After clearing away the enormous masses of snow from the palisade, they looked out from the inclosure through the loophole on the east, and all was stillness and silence. But the view was changed.

Pompous and soft, he "cottoned" to the grandeur with the instinct of a born satellite, and his eyes grew brighter, his body more shining and rotund, his back more concave.

This narrow belt is divided into branches; and its beautiful, but not uniform brightness, is interrupted by some dark places. As seen by us on the apparent concave celestial sphere, it deviates only a few degrees from a great circle, we being near the middle of the entire starry cluster, and almost in the plane of the Milky Way. If out planetary system were far outside the cluster, the Milky Way would appear to telescopic vision ...

The heavy black columns of the pines, glancing out of the concave shadow, also seemed a fitting background to what might have been a scene in a play.

... commonly sees himself in others, and the modern writer upon Italy is apt to believe that he can see others in himself. The reflection of an Italian upon the mental retina of the foreigner is as deceptive as his own outward image is when seen upon the polished surface of a concave mirror; and indeed the character studies of many great men, when the subject is taken from a race not their own, remind one very forcibly of what may be seen by contemplating oneself in the bowl of a bright ...

Allow me to explain this: sounds striking on concave surfaces are reflected from them, and, after reflection, converge to points which are the foci of these surfaces. It follows, therefore, that the ear may be so placed in one, as that it shall hear a sound better than when situated nearer to the point of the first impulse: again, in the case of ...

Both had the same difficulties to encounter —impassable bayous.

The front of his face seemed to have given way in general collapse. The lips were in a hollow; the cheeks were concave; the eyes had receded; and there were pits in the forehead. The pale silvery straggling hairs might have been counted. The wrinkled skin was of a curious brown yellow, and the veins, instead of being blue, were outlined in Indian red.

Instead of this, embarrassed by both lack of wind and lack of skill, their manoeuvres resulted in a curved line, concave to the enemy's approach; the horns of the crescent thus formed being nearer to the latter. Collingwood noted that this disposition facilitated a convergent fire upon the assailants, the heads of whose columns were bearing down on the allied centre; it does not seem ...

This "sea" is evidently concave in cross-section, the central portion being considerably lower than the margin, and these ridges appear to mark the successive stages of the change of level from the coast-line to the centre. They suggest the "caving in" of the surface, similar to that observed on a frozen pond or ...
