Inductive effects of 9-day chick embryo extract were tested by the method of explantation, immersing the presumptive epidermis of early gastrula of Triturus pyrrhogaster into the diluted chick embryo extract for two days, or wrapping the alcohol precipitant of chick embryo extract by the epidermis. By treating in the chick embryo extract, which was prepared by low speed centrifugation (3,000 r.p.m.), the isolated epidermis produced spinocaudal structures. When the presumptive epidermis was treated in the chick embryo extract prepared by higher speed centrifugation, the induction frequency was markedly decreased and nature of induction changed its regionality. The spinocaudal inductive effect of chick embryo extract disappeared when the sample was denatured by 70% ethanol, and induction of archencephalic structures was frequent.
