The present paper describes the results of some observations on the factors relating transplantability, using as material the MY mouse sarcoma and MY mouse carcinoma. The transplantability of tumors was observed concerning the strain, age, body weight, sexual maturity and sexual difference of the host. The transplantability showed a remarkable difference by strain of mice. The MY mouse carcinoma showed a high susceptibility to the D strain in which this tumor originated. The age and the body weight of the host seemed to give some influence upon transplantation of the tumor. In the MY mouse sarcoma, higher transplantability was obtained in the animals by 50 days from birth having 14-15gm of body weight than in older animals. In the MY mouse carcinoma, however, the mice of 30 days old, 10gm in body weight, were highly receptive to transplantation of the tumors. In the MY mouse carcinoma, the maturity of the host seems to influence on transplantation of the tumors. In the MY mouse sarcoma, the transplantability showed no remarkable difference by maturity of the host. And, there was no significant difference in the trans plantability of tumors by sex in both kinds of tumors here concerned. The age of the graft gave no remarkable influence for transplantability in the MY mouse sarcoma, while in the MY mouse carcinoma, young grafts ahowed better transplantability. Generally, the tumor pieces which have a solid histological structure were found to be better in transplantability, than in those of glandular structure. Based on the results of the preent observations, it is evident that the MY mouse sarcoma differs in many character from the MY mouse carcinoma.
