1909. J. W. Jenkinson, Experim. Embryol., 281. In very many, though not in all, instances the parts of the ovum—blastomeres or egg fragments—are totipotent…. The totipotence is, however, sooner or later lost. Ibid., 76. From other sources also there is evidence of a progressive loss of totipotentiality of the parts. Ibid. (1911), Sea Urchin, 292.
