    periosteum. The play of the muscles was hardly prevented by their being adlierent to each other. If processes of the extirpated bone had served as supports or pulleys for particular tendons, these were replaced, if not by new bony processes, yet in this way, that fibrous sheaths had been formed on the new bone, in wliich the tendons enjoyed a certain degree of motion fxom side to side. Heine observed after an extirpation of the fibula with its periosteum this state of things in the tendons of the peronei muscles, where they pass round the outer malleolus. The articular ends of the new bones were faund covered on the side turned towards the articular surface of the neighbouring bone with a strong and smooth fibrous or cartilaginous (?)i covering. Lying on the articular cartilage of the adjoining bone were found remains of the old articular capsule, or a thin, cellular tissue, which was continuous with a short, strong, fibrous cord passing to the newly formed bone. In other cases a new articular capsule was formed around the contiguous ends of bone, covered with a smooth synovial membrane, and containing a fluid resembling synovia. lu a newly formed joint of this kind, between the lower end of the femur, which had been reproduced after extirpation and the upper end of the tibia, even the crucial ligaments were found again. Sometimes a tolerably large space was found between the newly formed bone and the adjoining normal articular surface. In these cases the bone was prolonged into a very strong, but flexible, cord, wliich was con- nected by a soft, fibrous tissue to the adjoining articular surface. Tliis was the method also of connexion found between a newly formed rib and the costal cartilage. In rare cases there lay between the articular surfaces of the newly formed and the uninjured bone a meniscus, about aline in thickness, which, however, probably con- sisted of fibrous tissue. The above results apply equally to the extirpation of long, flat, and short bones. After the extirpation of the calcaneum, reproduc- tion of bony material took place. This served for the insertion of the tendo AchiUis, and articulated with the adjoining articular surfaces, the limb being perfectly useful. To sum up shortly the results wliich have been obtained by the different experimenters on the heaHng process after resection, in respect to the regeneration of bones, and in respect to the tissues ^ The query is the Author's.—Trans.
