... Owing to the want of wood, no coffins are used. The bodies are merely wrapped in a mat, or linen cloth, and covered with palm branches, over which the earth is thrown. When the branches decay, the earth falls in, and the graves are easily known by being concave, instead of convex. The place where the former sultans were buried, is a plain near the town; their graves are only distinguished from those of other people, by having a larger proportion of broken pots scattered about them. ...

The brush is floated down to the spot selected; the tops are weighted down with stones, and the butts left free, pointing down stream. Such dams must be built out from the sides, of course. They are generally arched, the convex side being up stream so as to make a stronger structure. When the arch closes in the middle, the lower side of the dam is banked heavily with earth and stones. That is shrewd policy on the beaver's part; for once the arch is closed by brush, ...

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.

By this process we may construct the curve QBZ, each point of which is also equally distant from the given point D, and from the concave instead of the convex arc of the given circumference. The difference between QD and QO being constant and equal to FO, and AB being also equal to FO, this curve is the other branch of the same hyperbola, whose major axis is equal to the ...

Then they shrank together in the middle and spread out on top till they looked like great domed mushrooms. Then the broad convex tops separated themselves entirely from their stalk-like bases and hung detached in the sky with daylight underneath. And then these mushroom tops stretched out laterally and threw up peaks of their own until there were distinct duplicate ranges, one on the earth and one in the ...

For the Roman columns on the right and left, finding the Gaulish and Spanish foot advancing in a convex line or wedge, pressed forwards to assail what seemed the flanks of the enemy's column; so that, being already drawn up with too narrow a front by their original formation, they now became compressed still more by their own ...

For instance, in trying to pick out a given criminal from his mere description you begin with the nose. Now, noses are all concave, straight, or convex. This Forbes had a nose that was concave, Burke says. Suppose you were sent out to find him. Of all the people you met, we'll say, roughly, two-thirds wouldn't interest you. You'd pass up all with straight or convex noses. Now the next point to observe is the ear. There are four general kinds of ...

That ripple was there, too, and in places it covered the wide backs of these huge ...

I do not know how a butterfly propels itself against a breeze with its quill-less wings, but we know that it does do it. As its wings are neither convex nor concave, like a bird's, one would think that the upward and downward strokes would neutralize each other; but they do not. Strong winds often carry them out over large bodies of water; but such a master flyer as the monarch beats its way ...

He placed at the ends of a leaden tube two spectacle glasses, both of which were plain on one side, while one of them had its other side convex, and the other its second side concave, and having applied his eye to the concave glass, he saw objects pretty large and pretty near him. This little instrument, which magnified only three times, he carried in triumph to Venice, where it excited the most intense interest. Crowds ...

The shelf of the receiver communicated with the wire of an immense galvanic battery. ...

... the opening years of the fourteenth century such lenses were in use, but this proves nothing as regards Bacon's connection with their invention. The knowledge of lenses seems to be very ancient, if we may judge from the convex lens of rock crystal found by Layard in his excavations at Nimrud. There is nothing to show, however, that the ancients ever thought of using them to correct defects of vision. Neither, apparently, is it feasible to determine whether the idea of such an application originated ...
