Page 80 - ... feet of him, when he will get under way again. But one must shoot at this creature once, if he wishes to see him throw his heart into his heels, and do the best he knows how. He is frightened clear through now, and he lays his long ears down on his back, straightens himself out like a yardstick every spring he makes, and scatters miles behind him with an easy indifference that is enchanting. Our party made this specimen "hump himself,
Page 100 - On moving the watch-glass, so as to bring one of the apertures on the side of the Sponge fully into view, I beheld, for the first time, the splendid spectacle of this living fountain vomiting forth from a circular cavity an impetuous torrent of liquid matter, and hurling along, in rapid succession, opaque masses, which it strewed everywhere around. The beauty and novelty of such a scene in the animal kingdom long arrested my attention...

The beauty and novelty of such* a scene in the animal kingdom, long arrested my attention, but after twenty-five minutes of constant observation, I was obliged to withdraw my eye from fatigue, without having seen the torrent for one instant change its direction, or diminish, in...
Page 208 - that Cuvier asserts the structure to have been the most heteroclite, and its characters altogether the most monstrous that have been yet found amid the ruins of a former world. To the head of a lizard it united the teeth of a crocodile, a neck of enormous length, resembling the body of a serpent, a trunk and tail having the proportions of an ordinary quadruped, the ribs of a cameleon, and the paddles of a whale.
Page 100 - If any species of sponge be examined, the holes with which the substance is everywhere pierced may be seen to be of two kinds, one of larger size than the rest, few in number, and opening into wide channels...
Page 127 - When a shower of rain falls, the highest portion of the mud-covered flat is usually too hard to receive any impressions; while that recently uncovered by the tide, near the water's edge, is too soft. Between these areas a zone occurs almost as smooth and even as a looking-glass, on which every drop forms a cavity of circular or oval form, and if the shower be transient, these pits retain their shape permanently, being dried by the sun, and being then too firm to be effaced by the action of the succeeding...
Page 206 - It is eleven feet high, and seventeen feet long to the base of the tail. The length of the tusks is twelve feet, of which two and one-half feet are inserted in the socket. The estimated height of the animal when living was from twelve to thirteen feet, and the whole length, adding seven feet for the horizontal projection of the tusks, from twenty-four to twentyfive feet.

I continued to watch the same orifice, at short intervals, for five hours, sometimes observing it for a quarter of an hour at a time, but still the stream rolled on with a constant and equal velocity.
Page 80 - Presently, he comes down to a long, graceful "lope," and shortly he mysteriously disappears. He has crouched behind a sage-bush, and will sit there and listen and tremble until you get within six feet of him, when he will get under way again. But one must shoot at this creature once, if he wishes to see him throw his heart into his heels, and do the best he knows how. He is frightened clear through, now, and he lays his long ears down on his back, straightens himself out like a yardstick every spring...
