its cast-off garment, its perishing shell. Cell-formation by divi- 
sion (called the “‘merismatic” or “ wandstandige”’) is that which 
obtains through the whole realm of vegetative development; 
while free cel!-formation occurs only in fructification. Thus, the 
same phenomenon, which, regarded as endogenous cell-formation, 
seemed so favorable to the importance of the cell as the vegeta- 
ble individual, when more justly comprehended only brings us 
back to the divisibility of the vegetable organism, repeated in the 
most heterogeneous spheres. But still more: even the cell whose 
contents are not converted by division into new cells, but re- 
main simple, presents phenomena which can hardly be reconciled 
with their view by those who regard such a cell as an individual, 
tents of the cell (amylum, chlorophyll and other pigment-vesicles, 
spherules of fat and, finally, the granules of the viscous cell-con- 
tents, whose chemical nature it is difficult to determine) ; and sec-
