16 DERIVATION OF ORGANIC BEINGS. 



The subject of these relations I propose to examine with 

 more detail after the survey, just referred to, of the repro- 

 ductive process in organic nature, but it seemed necessary 

 to premise so much here, as I have made use, in its course, 

 of forms of expression, to avoid circumlocution, which 

 would hardly be intelligible without such explanation.
