144 HEREDITY [AP. i 



of heredity and of the actual origin of the germ-cells 

 has progressed, biologists have given up this view 

 in favour of a belief in germinal continuity, that is, 

 that the germ-substance is derived from previous 

 germ-substance, the body being a kind of offshoot 

 from it. The child is thus like its parent, not 

 because it is produced from the parent, but because 

 both child and parent are produced from the same 

 stock of germ-plasm.
