Summary

Experimental results of different authors show that the attractive stimulus of the germinal epithelium for the germ cells in the chick embryo lasts less long than the reactivity of these cells to the same stimulus. However, both of them (stimulus and reactivity) last far longer than the period of the incorporation of germ cells into the primordia of the gonads. Each of them disappears when an important phase of differentiation is about to start in the group of cells concerned.
