heredity is jor the race 53 



complexity; the greater therefore is the 

 number of intermediaries through whose 

 hands — so to say — the acquisitions of the one 

 have to pass before they can be imparted 

 to the other. And not only will these engrams 

 — as they are called — be fainter on this ac- 

 count, and so require more repetitions to give 

 them any permanence ; but also for the same 

 reason they will lose in definiteness and detail. 

 Language, for example, will be inherited 

 not as speech but as mere tongueiness 

 and babble; art not as technical skill 

 but as mere handiness or pure mischief; 

 and so on. But if there is evidence of such 

 inheritance of forms of behaviour impossible 

 of acquisition at the unicellular stage, can 

 we say that the continuity between body- 

 plasm and germ-plasm ceased then? Can 

 we at all understand such facts without 

 recognising this continuity still?
