bearing of the doctrine of transmutation on the origin 

 of man, and his place in the creation. 



WHETHER MAN CAN BE REGARDED AS AN EXCEPTION TO THE RULE 

 IF THE DOCTRINE OF TRANSMUTATION BE EMBRACED FOR THE REST

WHY DECEPTIVE WHETHER THE STRUCTURE OF THE HUMAN BRAIN

DIFFERENT HUMAN RACES AND INDIVIDUALS DEVELOPED BY VARIATION

IN PHYSICAL STRUCTURE MAY RESULT FROM THE WORKING OF THE 

 SAME CAUSES CONCLUDING REMARKS. 



SOME of the opponents of transmutation, who are well 

 versed in Natural History, admit that though that doc- 

 trine is untenable it is not without its practical advantages 

 us a "useful working hypothesis," often suggesting good ex- 

 periments and observations, and aiding us to retain in the 

 memory a multitude of facts respecting the geographical 

 distribution of genera and species, both of animals and 

 plants, and the succession in time of organic remains, and' 

 many other phenomena which, but for such a theory, would- 

 be wholly without a common bond of relationship. 



It is a fact conceded by many eminent zoologists and
