Note 437 — GEOLOGICAL ILLUSTRATIONS, (continued 4)

The fact mentioned in the text brings to our recollection an interesting Memoir of Professor Walther, entitled, “On the Antiquity of diseases in Bones,” printed in Grasse and Walther’s Journal der Chirurgie und Augenheil Kunde, viii. From eleven specimens of bones of cave-bears found in the Caves of Sundwich, described by Walther, a proof is obtained, that the common forms of osseous diseases occur in them, just as they are observed at present in the human species, viz. necrosis, anchylosis, caries, exostosis, formation of new bony matter, thickening, thinning, and arthritic properties of diseased bones. Most of those diseases are such as would result from violent injuries, and the consequent very tedious organo-vital reaction. Such mechanical injuries would give rise to necrosis, caries, exostosis, &c. We can easily conceive, says Walther, how that the rapacious animals of a former world may have been exposed to violent mechanical injuries of their bodies, and of single parts of them. It is worthy of remark, that most of the diseased bones are of the lower jaw, the alveolar processes of it and the walls of single alveolæ. During the combats of the cave bears for their prey amongst themselves, or with other gigantic animals, the jaws and teeth must have experienced the greatest mechanical injuries. The necroses of the humeral bones are such as might result from a bruising of the bones, and the caries of the upper surface of the bodies of the lumbar vertebræ, may have been occasioned by external violence. Walther is also of opinion, that the cave-bears suffered from diseases of the bones not referrible to mechanical injuries. He remarks of a radius and a vertebra, whose arthritic condition he carefully describes, “These bones have experienced pathological changes, which could only arise from a long continued diseased condition of the nutritive process. They are very light, have an extremely thin crust, the greater part of their mass is of a spongy, very porous substance, and are uncommonly fragile. Such a change could not be produced by any external mechanical injury, nor by any slight action of the weather; but must proceed from a tedious constitutional disease, connected with a total change of the organo-forming plastic activity, and proceeding from a peculiar dyscrasia.” Hence it is probable, these cave-bears even suffered from gout, scrophula, and other similar diseases.
