Abstract
THE work of Bounoure1 and Blackler2 on three anuran species has shown that, in fixed and sectioned material, and after the application of suitable stains, the embryonic sites that contain primordial germ-cells may be recognized at all developmental stages from the fertilized egg to the tadpole. A technique for the transfer of the gonocytes between one embryo and another has been devised as a first step in a genetical analysis of abnormal embryos produced in this department by the transplantation of somatic nuclei into unfertilized eggs of Xenopus.
