 perceived, he is found as perfectly formed and organised 

 as he is now, there are no transition stages of man's 

 existence, nor of any other animal. It is true that the 

 simpler forms of both animal and vegetable existence were 

 created first, but this was in accordance with the state of 

 the earth's surface, which was not at first suitable to the 

 requirements of the higher animals, which were only created 

 when the earth was in a state suitable to receive them. 



But when the surface of the earth was still more de-

 there can be no doubt that G-od in His wisdom caused all 

 these changes to precede the creation of man, that he might 

 lack nothing to confer happiness on him, nor objects to 

 exercise his faculties upon. 



Animals are divided into two great natural families, the 

 Invertebrate and the Vertebrate, the former having neither
