daily suitable for transportation by the uterus. It will be of much interest to learn whether migration of the pig's ovum can be demonstrated before the tenth day, while it is still minute and spherical.
If the forgoing discussion has any bearing upon the clinical side of the question, it is that internal migration of the human ovum is still to be regarded as occasionally possible, more especially perhaps in cases of multiple gestation. Twin embryos were present in the case of Andrews, previously mentioned, which is up to the present the most satisfactory case among those interpreted as examples of this form of migration in the human.
