The karyokinetic figure is usually symmetrically developed after the strongest centrifuging in spite of the fact that rearrangements of granules are more extensive than with lower centrifugal powers. The reason for this must lie in the uniform character of the protoplasm, which is produced in the hyaline band by strong 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. ).
