Some of these cases might be referred to the sarcomata and some to carcinomata, but that is impossible unless they could be rexëamined by a reliable pathologist, as was done by Eve, who examined a so-called medullary tumor from the kidney of an infant, which had been deposited in the museum of the Royal College of Surgeons, London, in Hunter's time, and discovered that it belonged to that rare group of tumors which have been variously designated as rhabdomyosarcoma or as myosarcoma striocellulare.
