But they are the only existing members of the group which possess chambered, siphunculated shells; and it is utterly impossible to trace any physiological connection between the very peculiar structural characters of a cephalopod and the presence of a chambered shell.
To humans the buzzard pays a deeper meed of respect he hangs aloft longer; but in the end he comes. No scavenger shark, no carrion crab, ever chambered more grisly secrets in his digestive processes than this big charnel bird. Such is the way of the buzzard. The squire missed his afternoon nap, a thing that had not happened in years. He stayed on the front gallery and kept count.
A suggestion which may naturally enough present itself is, that these curious bodies are the result of some process of aggregation which has taken place in the carbonate of lime; that, just as in winter, the rime on our windows simulates the most delicate and elegantly arborescent foliage proving that the mere mineral water may, under certain conditions, assume the outward form of organic bodies so this mineral substance, carbonate of lime, hidden away in the bowels of the earth, has taken the shape of these chambered bodies.
Though now only twenty-one years old, he had given seven years of study and labor to his "revolver," and had brought it to a state of perfection which was far in advance of his early hopes. "At this time, and, indeed, for several years after, he was not aware that any person before himself had ever conceived the idea of a fire-arm with a rotating chambered breech.
The great oyster family dates from here. Cephalopods are now to have their day. The archaic Orthoceras lingers on into the Triassic and becomes extinct, but a remarkable development is now at hand for the more highly organized descendants of this ancient line. We have noticed that in the Devonian the sutures of some of the chambered shells become angled, evolving the Goniatite type.
After I had learned a great many interesting things about the life and habits of the children of the sea how in the midst of dashing waves the little polyps build the beautiful coral isles of the Pacific, and the foraminifera have made the chalk-hills of many a land my teacher read me "The Chambered Nautilus," and showed me that the shell-building process of the mollusks is symbolical of the development of the mind.
Sitting on the edge of his chair, half-crouching, his head, with its long, unkempt, white hair, bent slightly to one side, he concentrated upon this chambered silence the full powers of his senses. He hardly breathed. The other person in that room could not be breathing at all, it seemed. No, there was not a breath, not the stirring of a sole on wood, not the infinitesimal rustle of any fabric.
The Chambered Shells, or the Cephalopods, represented chiefly in the earlier periods by the straight Orthoceratites described in a previous article, are now curled in a close coil, and the internal structure of their chambers has become more complicated. The subjoined wood-cut represents a characteristic Chambered Shell of the Carboniferous age.
The Saxons were determined to-day to go farther afield than their walks had hitherto taken them. The local guide-book mentioned some prehistoric menhirs and a chambered barrow on the top of Red Ridge, a distant hill, so they had fixed that as their Mecca.
The tomb was concealed by a huge oval mound more than 100 yards in length. The famous Mont S. Michel is an artificial mound containing a central megalithic chamber and several smaller cists, some of which held cremated bodies. Chambered mound at Fontenay-le-Marmion, Normandy.
