PROFESSOR VIRCHOW AND EVOLUTION 419 



men, I think we should be abusing our power, we should 

 be imperilling our power, unless in our teaching we re- 

 strict ourselves to this perfectly safe and unassailable do- 

 main. From this domain we may make incursions into the 

 field of problems, and I am sure that every venture of that

Virchow's position could not be made clearer by any 

 comments of mine than he has here made it himself.

 In school teaching the former ought to be excluded. And, 

 as he assumes it to be still in its hypothetical stage, the 

 ban of exclusion ought, he thinks, to fall upon the theory 

 of evolution. 



I now freely offer myself for judgment before the tri- 

 bunal whose law is here laid down. First and foremost,
