Osteological Symmetry of the Camel. 537 



1 . That though the hardness and durability of bones peculiarly- 



fit them for inquiries similar to that detailed in these pages ; 

 yet as the bones always arise from and are moulded by the 

 softer tissues, the whole organic system is determinable in 

 its proportions. 



2. That the relation of the forms of extinct animals to the 



forms of animals now living, — the affinities of species and 

 genera, — the simultaneous growth of the parts of the same 

 animal, and the rates of such growth comparatively in 

 other animals ; — the improvement of domestic races, — 

 even the structure and development of the human frame, — 

 are all matters both of physiological and of numerical 

 study. , / , . 



3. That Zoology is, to an equal extent with the departments of 



knowledge that regard inanimate things, susceptible of 

 a classification established on the sure basis of number.
