THE MOVEMENT OF THE CELL. 125 



the germ of today's biological dicussion, 

 which is seeking so desperately to account 

 for heredity, with the practical purpose of 

 somehow controlling it, or at least directing 

 it into certain improved channels. The Dar- 

 winian gemmule, though supposed to be only 

 physical, has certainly produced many gem- 

 mules of mind, which are still being born; 

 and again it is to be noted how the psyche 

 of the biologists is itself a kind of cellular 

 process in this sphere, the deeper reason be- 

 ing that the cellular process likewise is at last 

 psychical. The gemmule, then, may be con- 

 sidered the germinal idea out of which so 

 much recent biology has evolved. But with 

 it the question again comes up : is it the real 

 origin of Life? Hardly, though it is the ori- 

 gin of itself. 



Here, then, dawns a new form of the old 

 aphorism already cited, though this new form 

 has not been expressed as far as we are 

 aware. Following the analogy of its previous 

 Latinized sentences, one may set it down 

 thus: in uix yemmula e gemmula. Such is 

 the fourth aphorism or aphoristic model in 

 this field, uttering the last phase of the bio- 

 logical evolution of the cell, inclusive or per- 

 chance typical of all the rest. For it is now 

 confessedly the idea, hypothetical, unseen, 

 ultra-microscopical, whereas the other three,
