 to be altogether wanting, and in others to contra-

 inadequate to accomplish the results ascribed to 

 them. 



First, he assumes that these various forms were

 from another variety ; in animal life particularly that 

 each variety of animal form is produced or evolved 

 from some other different animal form, and that 

 these new varieties have arisen from some changes 

 in cognate or nearly similar species. For example, 

 he supposes that Man has sprung from some variety 

 produced either by Natural or Sexual Selection in 

 those apes who physically bear the most resemblance 

 to the human frame. But this theory is totally un- 

 supported by any positive fact. No naturalist ever

 in any other animals. Mr. Darwin seems to consider 

 that he has proved his case when he. has shown that
