CHANGES OP ORGANIC FORMS, 

 to keep them in harmony 

 with the Changed Condi- 

 tions ; and as the changes 

 of conditions are perma- 

 nent changes, in the sense 

 of not reverting back to 

 identical previous condi- 

 tions, the changes of or- 

 ganic forms must be in the 

 same sense permanent, and 

 thus originate SPECIES.
