Organisms Covsisting of One Cell 



279 



only a tithe of whicli has been used in this review, it is hard 

 to sec how any one can avoid recognizing that the fact that 

 the animals usually consist of a single cell, is really of 

 secondary importance. Neither descriptively nor interpre- 

 tatively (if one insists on making a sharp distinction between 

 the two) do the generalized elements cytoplasm and nucleus, 

 held to be the irreducible minima of the cell, throw any but 

 the vaguest, most general light on innumerable of the struc- 

 tures and processes brought under notice.
