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, mergly 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.
