FIG. 5. changes together with the definitive nuclear phenomena charac- teristic of the low point in the division rate. The term endomixis was not used in that broad sense when first employed by Woodruff and Erdmann and it is unprofitable to extend it now. Applying the term strictly to the complicated reorganization process of the cell does not deny the undoubted 'fact that these changes are but the expression of the climax of a series, of physiological phenomena which probably extend back to the consummation of the previous endomictic period. So, it seems to be a more or less academic ' question whether rhythms and endomixis are independent. Certainly the rhythms occur for a while without endomixis in sensu stricto—but in all such cases the culture has died before very 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. ).
