Homoplastic skin transplantations were effected on 8-day-chickens of Gallus domesticus (Wyandotte race). The animals were divided into the following groups according to the type of treatment to which they were submitted: group I received skin homotransplant, group II was bursectomized before skin homotransplant, group III was thymectomized before skin homotransplant, group IV was thymo- and burso- ectomized before skin homotransplant. The technique of surgical bursectomy and thymectomy operations were related. The transplanted skin in thymectomized chickens showed an average time of survival longer than that of the skin in the chickens which had been bursectomized. This and the other observations suggest that only the thymus plays a role in the immunological reaction taking place after skin homotransplantations.
