tion " that the law that perfect individuals may be 

 virginally born extends to the higher forms of 

 life." Then let us turn to Huxley's article and 

 see what he really does say. 



Treating of the whole subject of agamogenesis 

 in the widest possible way by including it under 

 the more general process of cell-multiplication, 

 Huxley says : " Common as the process is in plants 

 and in the lower animals, it becomes rare among 

 the higher animals. In these, the reproduction 

 of the whole organism from a part, in the way in- 

 dicated above, ceases. At most we find that the 

 cells at the end of an amputated portion of the 

 organism are capable of reproducing the lost part, 

 and in the very highest animals even this power 

 vanishes in the adult. . . . Throughout almost 

 the whole series of living beings, however, we find 

 concurrently with the process of agamogenesis, or 

 asexual generation, another method of generation, 

 in which the development of the germ into an or- 

 ganism resembling the parent depends on an influ- 

 ence exerted by living matter different from the 

 germ. This is gamogenesis, or sexual generation." l
