The Mush Ox, so 

 .called from the 

 flavor of its flesh, 

 inhabits Arctic 

 North America.* It 

 feeds an grass and 

 lichens. The horns 

 widen at the base, 

 so as entirely to 

 cover the crown of 

 the head. 



Difference be- 

 tween Herbivora 

 and C arnivora. f 

 — A distinguishing 

 feature of the Euminants is the elevation of the heel, which 

 conipels the animal to walk upon its nails (the Camelidge 

 excepted). The Carnivora bring the entire toes to the ground, 



* The Esquimaux hunters will attack this irritahle animal with only a knife, and 

 turning around quicker than it can wheel, stah it to death. 



t A comparison of Figs. 27, 65, 77, 83, will show that the differences in the various 

 parts of the skeleton are those of relative size and adaptation rather than of numher.
