by the tumor with transplanted muscles from dogs. Gluck has induced
reproduction of lost tendons by grafting them with cat-gut, and
according to Ashhurst, Peyrot has filled the gaps in retracted tendons
by transplanting tendons, taken in one case from a dog, and in another
from a cat.

Nerve-grafting, as a supplementary operation to neurectomy, has been
practiced, and Gersung has transplanted the nerves of lower animals to
the nerve stumps of man.

Bone-grafting is quite frequently practiced, portions from a recently
amputated limb, or portions removed from living animals, or bone-chips,
may be used. Senn proposed decalcified bone-plates to be used to fill
in the gaps. Shifting of the bone has been done, e.g., by dividing a
strip of the hard palate covered with its soft parts, parallel to the
fissure in cleft palate, but leaving unsevered the bony attachments in
front, and partially fracturing the pedicle, drawing the bony flaps
together with sutures; or, when forming a new nose, by turning down
with the skin and periosteum the outer table of the frontal bone, split
off with a chisel, after cutting around the part to be removed.
Trueheart reports a case of partial excision of the clavicle,
successfully followed by the grafting of periosteal and osseous
material taken from a dog. 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. Rodgers used
grafts from the under wing of a young fowl, as suggested by Redard,
with good resu
