THE OXYGEN CONSUMPTION OF ARTIFICIALLY ACTIVATED AND FERTILIZED CHÆTOPTERUS EGGS

JEAN BRACHET 1

1 From the Marine Biological Laboratory, Woods Hole, Mass., Biology Department, Princeton University, and the Faculty of Medicine, University of Brussels

1. The oxygen consumption of unfertilized Chætopterus eggs drops in the same proportion whether they are fertilized or activated with KCl.

2. The increase in respiratory rate after that initial drop is much faster in fertilized eggs than in activated (differentiating without cleavage) eggs.

3. The lower respiratory activity of the activated eggs is linked to their special type of development.
