minal areas, etc. The facts of homology and ontogeny as related 
to phylogeny leave much to be desired ere it will be possible to 
sustain the earlier conceptions of recapitulation and its enormous 
implications as to biological philosophy. 
6. Amitosis as a factor in cytogenesis is a question of fact. 
Cumulative evidence from almost every field of cytology goes to 
show that it is neither rare, nor limited to senile or pathologic 
conditions of cells or tissues. Its significance in cytogeny is 
difficult to overestimate. It is not unknown as a factor in embry- 
ogeny in any of the great phyla of nature. As a fact it is no less 
sacred than any other, and must be reckoned with in any final 
doctrine of development.
