The rates of oxygen consumption were lollowed for three hours. When the experiments were performed in this \\ ay, over 50 per cent of the eggs had cleaved to 8 and 16-cell stages at the end of the experiment, and over 80 per cent of the eggs had matured. The data are presented in 1 ii;. 2, in which the ordinate represents the amount of oxygen consumption in cubic millimeters and.
