TRANSMISSION OF CHARACTER 191

 conditions are hereditary. 



This idea is the basis of Lamarckian transformism 

 and Darwin has recourse to it whenever natural selec- 

 tion does not seem to furnish him with an adequate 

 explanation for certain facts. For we must not for- 

 get that Darwin accepts explicitly the heredity of 

 acquired characters and the name of Darwinian as- 

 sumed by scientists who deny it is a misnomer. Many 

 quotations from "The Origin of Species" support our 

 statement : 



"Changed habits produce an inherited effect as in 

 the period of the flowering of plants when transported 

 from one climate to another. With animals the in- 

 creased use or disuse of parts has had a more marked 

 influence; thus I find in the domestic duck that the 

 bones of the wing weigh less and the bones of the leg 

 more, in proportion to the whole skeleton, than do the

 view which has been suggested that the drooping is
