Bone-Caves in Pennsylvania.—Professor Leidy in company with Dr. T. C Porter, of Easton, Pennsylvania, visited, in August last, Hartman's Cave, near Stroudsburg, Pennsylvania, on the invitation of Mr. T. D. Paret, of that place, and examined a number of interesting animal and other remains which were found there. The cave is partly filled with a bed of clay ten feet deep, on which rests a thin layer of stalagmite, and on this about a foot of black, friable earth mingled with animal and vegetable remains. The cave appears to have been too small to be inhabited by the larger carnivora, and no large entire bones of them were found, but about a half-bushel of fragments and splinters of limb-bones of smaller and large animals have been collected, many of which exhibit marks of having been gnawed, whether by rodents or small carnivora Professor Leidy does not assume to decide. Some of the splinters are derived from such large and strong bones that it is questionable whether even the largest carnivora could have produced them, and are presumed to be remnants of human feasts, in which the bones were crushed to obtain the marrow. A few of the bones are somewhat charred, among them a small fragment of a bison's jaw with a molar tooth. Most of the bones are of species still living, but some of them, as jaws of the reindeer, bison, and wood-rat, are of animals no longer belonging to the fauna of the State; and a few, as the teeth of the Casteroides Ohioensis,
