into a struggle between tile older evolu- 

 tional and the newer developmental me- 

 chanical interpretations of morphology. It 

 is difficult to see how the Bower steriliza- 

 tion theory can be overturned without car- 

 rying with it the whole scheme of Arche- 

 goniate phylogeny which plant morphology 

 owes to the classic work of Hofmeister. 

 Nothing can be more apparent under ac- 

 cepted beliefs than that from Oedogonium 

 sporophytes upward there is a progressive 

 change from an entirelj'^ sporogenous plant 

 body to one in which the great part of the 

 sporogenous tissue is replaced by sterilized 

 areas. It is, however, possible that both 

 diiferentiation and the ' true metamor- 

 phosis ' of Goebel have gone on together in 

 the phylogenetic series. The experimental 

 method would doubtless throw more light 

 on the whole matter than the speculative 

 phosphorescence which, up to the present, 

 has been the chief illumination.
