Growthis the enlargement of the cell, not merely a swollen condition, and thisincrease in size is within definite limits for each species, which can bedetermined by statistic study. As long as division is not precededby nuclear division, the term fission is applicable. Certain studentsof the group claim that there is a division of the nuclear substance(Fig. 6), and Fuhrmann actually figures division of the nuclear mate-rial in such forms as Bacillus nitri,Micrococcus butyricus, Spirillumvolutans and the potato then division of thenuclear substance precedes thatof cell division, and if that phenom-enon is found general, the termfission is no longer
