70 THE GENETIC AND

 devoid of any " certain proof ! " Where, then, are the 

 other bones ? Let us see them ! till then we decline 

 to believe in them. According to Virchow, we ought 

 rather to assume that the lower jaw was the only bone 

 in the body of these extraordinary beasts. Are there 

 not, in fact, snails, in which an upper jaw is the only 

 representation of a skeleton. 



We cannot omit taking this opportunity of casting 

 a side glance at the very hazardous position which 

 Virchow, in total opposition to his boasted cool scepti- 

 cism, has taken up in anthropology as it is called, now 

 his favourite branch of science. In his Munich address 

 he tells us that he is pursuing the study of anthropology 

 with delight, and then asserts that " the quarternary 

 man " is an universally-accepted fact. Quite apart 

 from this statement, we have seen that Virchow can 

 never attain to a profound and really scientific study 

 of anthropology simply for this reason, that he is lack-

 morphology which is indispensable to it; nay, com- 

 parative anatomy and ontogenesis must be, according to 

 him, unpermitted speculations and the phylogenesis of 

 man, the key to all the most important questions of 

 anthropology, being based upon these, is devoid of all 

 certain proof. All the more must we wonder at the
