The case of the frog is in principle similar to that of the newt. But the experiments conducted from time to time on the frog have suffered so much from unforeseen complications, that the con- clusions drawn from them w^ere for a long time misleading. The chief difficulty arises from the fact that the eggs of Anura have long defied attempts to secure the constriction and separation of blastomeres. Experimental technique has therefore been largely.
