While doubtless containing an element of truth, this explanation is, however, no more adequate than Balfour's rule regarding the relation between deutoplasm and rhythm (p. 366); for innumerable cases are known in which no correlation can be made out between the distribu- tion of inert substance and the inequality of division. This is the case, for example, with the teloblasts mentioned above, which contain no deutoplasm, yet regularly divide unequally. It seems to be inap-.
