(173.) In concluding this part of our volume, we 
consider that the facts now stated are sufficiently strong 
to establish the propositions with which this investi- 
gation was commenced. We have seen, 1. That animals 
are distributed upon a plan, sufficiently obvious in its 
leading outlines, to be comprehended and defined ; and, 
2. That this plan is found to harmonise, in many re- 
markable ways, with that circular disposition which is 
the first law of natural classification.
