From Harrison, in the "Anatomical Record,'' Vol. 2. have been those of Carrel on mammals. lie has removed sections of arteries of one animal and replaced them with pieces of vessels taken from another. He has even made this graft successfully with vessels which had been kept in an ice chest for several weeks after death. Thus a piece of a human artery taken from an amputated leg and pre- served for twenty-five days in cold storage was used to replace a piece of the aorta of a small dog. The graft took and the dog recovered and lived for over four years, during which time she bore several litters of pupi)ies, finally dying during.
