The beginnings of embryonic development : A symposium organized by the Section on Zoological Sciences of the American Association for the Advancement of Science, cosponsored by the American Society of Zoologists and the Association of Southeastern Biologists, and presented at the Atlanta meeting, December 27, 1955.

If this enzyme is locahzed in the mitochondria, these would ulti- mately be segregated only in the ectodermic blastomeres. Similar results have also been obtained by Mancuso (1955a) in Physa. Mitochondria segregated in the animal pole of the egg have been actually observed by Ries and Gersch (1936) in Aplysia. How- ever, these authors were not able to follow their destiny in the following development. They supposed, probably founded on.
