Dividing eggs in a diver containing atmospheric air The eggs seem to develop just as well in the diver where a high oxygen tension is prevailing as they do in the control (an open Petri-dish floating in the same thermo- stat as is used for the diver experiments). However, the respiratory waves might conceivably be influenced by the high oxygen tension in the diver without the cell division itself being in any way affected. The experiment, the result of which is shown in Figure 3, however, would seem to rule this possibility out. In this case the diver is filled with atmospheric air, and the eggs respire and divide normally until the 4th cleavage is completed. After this time signs of oxygen deficiency appear : respiration goes down and the cells divide more slowly than the controls outside the diver. The oxygen tension (expressed in per cent of one atm.) can, with fair accu- racy, be calculated from the change in equilibrium pressure of the diver, assuming the oxygen pressure to be per cent of an atm. at the moment when the diver is Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
