ON ZOOLOGY. 



derived from the surface of the earth, requiring a 

 finer division of its several particles before a so~ 

 lution can be commenced, and whose food from 

 being more uniformly at hand is obtained at much 

 shorter intervals, are slower in their mode of 

 eating and less voracious ; and these are more 

 easily domesticated than the former class, many 

 of which under no treatment can be rendered 

 subservient to human control. To enable the 

 graminivorous animals therefore to prepare their 

 food for digestion, in the place of sharp, cutting 

 teeth, nature has given them those which are par- 

 tially hollow and broad, that the food may be 

 completely divided by mastication before it be 

 passed into the stomach ; and as its digestion 

 afterwards is not so quickly affected as in carni- 

 vorous animals, it is subjected to the action of 

 frequently more than one stomach ; in the ox 

 species, to as many as four; and in the latter, as 

 well as in several other of the graminivorous 

 class, to the further process of rumination or 

 second mastication, previously to its final solu- 

 tion ; the principal stomach being usually longer 

 and thinner than that of carnivorous animals; 

 while in the place of claws to the feet, the 

 graminivorous have hoofs to give them a stronger 

 hold on the ground. Those quadruped animals 

 again which feed on the fruit and seeds of trees, 

 Jiave their legs formed for climbing, and their feet 

 (like hands) for grasping round substances ; and
