Robson and Hayes of Rochester, N.Y., have successfully supplemented excision of spina bifida by the transplantation of a strip of periosteum from a rabbit.

Poncet hastened a cure in a case of necrosis with partial destruction of the periosteum by inserting grafts taken from the bones of a dead infant and from a kid.

Ricketts speaks of bone-grafting and the use of ivory, and remarks that Poncet of Lyons restored a tibia in nine months by grafting to the superior articular surface.

Recently amalgam fillings have been used in bone-cavities to supplant grafting.
In destructive injuries of the skin, various materials were formerly used in grafting, none of which, however, have produced the same good effect as the use of skin by the Thiersch Method, which will be described later.
Rodgers, U.S.N., reports the case of a white man of thirty-eight who suffered from gangrene of the skin of the buttocks caused by sitting in a pan of caustic potash.

When seen the man was intoxicated, and there was a gangrenous patch four by six inches on his buttocks.
