The nutrition of the bones as a whole is disturbed, resulting in alterations both in the ossein and.

The fractures which occur so frequently during the osteoclastic phase have well-marked peculiarities. The extravasation of blood is trifling, and no callus forms, even when the ends of the bones are immobilised by external aid ; if the ends are left free, they soon become worn and polished by rubbing against one another. In the neighbourhood of the articulations and ligamentous insertions the periosteum soon undergoes change, and it is not uncommon to find sub-periosteal and intra-osseous extravasations of blood. Germain has also noted in horses the disappearance of the interver- tebral and articular cartilages, and the frequent occurrence of anchylosis, true or false. C.
