The single centrosome (for there is nowone only in each daughter cell) again becomes tuckedinto the centre of the transparent nucleus—whichconsists of one half of the original spindle, and thusthe cycle of mitosis is completed. Doubtless eachchromosome granule divides during some part of thecycle, but owing to their minute size we have notbeen able to see their division. The cells, of course, do not usually divide indefinite stages such as the aster and diaster, althoughsometimes a cell will be found which presents oneof them. Sometimes one sees that the chromosomesmay be dividing in one part of the cell, while somechromosomes in another part
