 ... heraldic Shield is generally flat; but sometimes the curved edges are made to appear as if they had been slightly rounded off. Some early Shields are represented as bowed—hollowed, that is, in order to cover more closely the person of the bearer, and consequently having a convex external contour, as in No. 39. In early examples of bowed Shields the whole of the armorial blazonry is sometimes displayed on the face of that portion of the Shield which is shown. Aridge, dividing them in pale, but not necessarily in any way ...

These, split in half and cleared of all sap, made very effective roofing, placed alternately in concave and convex form, so that the ridges of the two lengths of trunk placed bark upward rest in the hollow of the intervening trunk. Naturally, all rain water drains off the convex half into the concave trunk and flows down these gullies into the ...

But on account of the convex face of the work on their side the rebels could not reach us with their fire without exposing themselves above the breastwork.

What I noticed under the superficial aspect of vapid sweetness was her convex, obstinate forehead, and her small, red, pretty, ungenerous mouth. But then I am an observer with strong prejudices. Most of us were fetched by her white, swan-like neck, by that drooping, innocent profile. There was a lot of latent devotion to Davidson's wife hereabouts, ...

One side of it was curving inward, as though a convex, black shadow were sweeping across it. My memory went back. It was thus, that the darkness had come, before our last parting.

While roughly speaking the limbs are symmetrical, each side not only has variety in itself, but there is usually variety of opposition. Supposing there is a convex curve on the one side, you will often have a concave form on the other. Always look out for this in drawing limbs, and it will often improve a poorly drawn part if more of this variation ...

... drop directly from the royal-mast into the sea, but that my fall was broken by something half-way down. This proved to be correct, as I afterwards learnt. The ship chanced to be under full canvas at the time, and the maintopsail, swollen out by the fresh breeze, had caught me on its convex side as I came down. From this I had bounded off again, but the impetus of the fall had been thus lessened; and the second pitch into the sea was not so violent as it would otherwise have been. Otherwise, indeed, I should have been crushed upon the surface of the water, never to breathe ...

... beautiful; and, lastly, the sun's upper limb rose in brightest saffron above the dimmed and spurious horizon of north-east cloud. The panorama below us emerged dimly and darkly from a torrent of haze, whose waving convex lines, moving with a majestic calm, wore the aspect of a deluge whelming the visible world. Martin the Great might have borrowed an idea from this waste of waters, as it seemed to be, heaving and breaking, surging and sweeping over the highest mountain-tops. We saw nothing ...

... trouble stirs, and the waters boil and eddy. These are the lower rapids, a sight more terrifying than the Falls, because less intelligible. Close in its bands of rock the river surges tumultuously forward, writhing and leaping as if inspired by a demon. It is pressed by the straits into a visibly convex form. Great planes of water slide past. Sometimes it is thrown up into a pinnacle of foam higher than a house, or leaps with incredible speed from the crest of one vast wave to another, along the ...

... latter being technically called the error of capacity. If a glass tube of small bore be plunged into a vessel containing mercury, it will be observed that the level of the mercury in the tube is not in the line of that of the mercury in the vessel, but somewhat below it, and that the surface is convex. The capillary depression is inversely proportional to the diameter of the tube. In standard barometers, the tube is about an inch in diameter, and the error due to capillarity is less than .001 of an inch. Since capillarity depresses the height of the column, cistern barometers ...

My female neighbour insisted on using the edge of my hammock for a foot-rest, and, to add to my general discomfort, my hammock persisted in assuming a convex shape rather than a more conventional and convenient concave, which put me in constant danger of being thrown headlong into the river, only a few inches away. Finally, I took my hammock down from its fastenings and went aft where I found a vacant canoe among those ...

... Elsewhere we have the problem, How does one association exclude another? Only, as J. S. Mill replies, when one idea includes the idea of the absence of the others.[555] We cannot combine the ideas of a plane and a convex surface. Why? Because we have never had both sets of sensations together. The 'commencement' of one set has always been 'simultaneous with the cessation of another set,' as, for instance, when we bend a flat sheet of paper. The ...

It ridiculed Columbus; put Roger Bacon in jail because he discovered the principle of concave and convex glass; condemned Socrates, and jeered Fulton and Morse.

The crystalline humor, or lens, is situated immediately behind the aqueous humor, a short distance back of the pupil, and is a perfectly transparent double convex lens, closely resembling in shape the common burning glass. This resemblance does not stop here; for this lens, like the burning glass, possesses the property of converging the rays of light which fall upon it, and bringing them to a focus. ...

... cabochon cutting, is probably the most ancient. The term comes from a French word signifying a bald pate (caboche, from Latin cabo, a head). The usual round cabochon cut closely resembles the top of a head in shape. Cabochon cut stones usually have a flat base, but sometimes a slightly convex base is used, especially in opals and in moonstones, and some stones of very dense color are cut with a concave base to thin them and thus to reduce their color. The contour of the base may be round, or oval, or square, ...

The great attention which Mr. Telford has devoted, to give to the surface of the road one uniform and moderately convex shape, free from the smallest inequality throughout its whole breadth; the numerous land drains, and, when necessary, shores and tunnels of substantial masonry, with which all the water arising from springs or falling in rain is instantly carried off; the great care with which a ...

... snowy top of one of the Sierra Nevada. Looking eastward to the horizon line of the Mediterranean, my sight extended so far, in the wonderful clearness of the air, that the convexity of the earth's surface was plainly to be seen. The sea, instead of being a plane, was slightly convex, and the sky, instead of resting upon it at the horizon, curved down beyond it, as the upper side of a horn curves over the lower, when one looks into the mouth. There is none of the many aspects of Nature more grand than this, which is so rarely seen, that I believe the only person who has ever ...

The early object-glass, or large glass at the end, was a single convex lens (see Fig. 8, p. 113, "Galilean"); the modern one is, on the other hand, composed of two lenses fitted together. The attempts to construct large telescopes of the Galilean type met in course of time with a great difficulty. The magnified image of the object ...

Its main and lower portion is not divided into nave and transept, but seems like a system of huge semi-cylinders erected on their bases, and united with reentrant angles, their convex surfaces toward us, so that the ground-plan might be called a species of quatre-foil. In each of the convex faces is an admirably proportioned door-way, a Gothic arch with deep-carved and elaborately fretted mouldings, so wonderfully perfect in its imitation that ...

... Asiatic and African elephants have established them into separate species. The enamel of the grinders is so placed in the latter, as to form lozenges; and in the former, parallel-fluted ribbons. The ears of the African animal are much larger, and the shape of his forehead is more convex. Although it was from this country that the Romans obtained all their clever, well-trained elephants, the natives now never think of making them useful. Connected with this, I was once much amused by the proposal, seriously suggested, that if we English would go among the savage tribes ...

That ripple was there, too, and in places it covered the wide backs of these huge waves all over; but never was it found ...
