This farther distribution is divided into beasts, 

 birds, and fishes, and is founded, with regard to 

 quadrupeds, partly on the external, and corres- 

 pondent internal structure of the feet, and partly 

 also on the habit of rumination. 



The system may be thus stated. 



Unclean. 



I. QUADRUPEDS. 

 Solipedes. 



All quadrupeds having but one hoof, as the 

 horse and ass ; or having the hoof not entirely, 

 but only partially divided into two parts, as 

 the camel ; or having the hoof, though entirely 

 divided, yet into more than two parts ; or having 

 the hoof entirely divided externally, yet not 

 having, besides this external structure, its internal 

 anatomical constitution strictly correspondent to 

 this formation, as the swine, (for though the 

 outward appearance of the hog's feet be like that 

 of a cloven-footed animal, yet, internally, they 



pation, and so would understand by the direction recorded 

 to have been given to Noah, merely that he should take a 

 larger number of the more useful animals than of those not 

 so useful. Others, perhaps with more propriety, regard 

 the terms as one among many of those references to a 

 patriarchal church, which they think they discern in the 

 brief, abrupt, and very condensed history of the old 

 world.
