[I might with propriety have added to the foregoing criticisms, 

 the remark that Professor Owen has indirectly conferred a great 

 benefit by the elaborate investigations he has made with the view of 

 establishing his hypothesis. He has himself very conclusively proved 

 that the teleological interpretation is quite irreconcilable with the 

 facts. In gathering together evidence in support of his own con- 

 ception of archetypal forms, he has disclosed adverse evidence which 

 I think shows his conception to be untenable. The result is that 

 the field is left clear for the hypothesis of Evolution as the only 

 tenable one.]
