rate and Warm countries. The Wild Horse (E. ca- 

 ballusferus) lives in the Deserts of Arabia, and in 

 Java. The species of those Horses which, after 

 being domesticated, have become wild, are to be met 

 with in Russia, as far as the 52d or 53d degree N.L. 

 The Wild Ass, the Zebra, and the Quagge inhabit 

 warm countries only. Of all these species, the 

 Cloven-Footed Horse (E. bisulcus) in Chili, and our 

 common one, live only as domesticated animals to- 

 ward the Frigid Zone. There are Horses in Iceland 

 of a small size ; but not any in Greenland, Kaint- 

 chatka, or Lapland. The district which, in the 

 level, coincides with the 66 N.L., is accordingly to be 

 regarded as a limit to the spreading of this Genus. 



The Order of CARNIVOROUS ANIMALS (Fera), al- 

 though extending over all the Zones, yet displays its 

 most horrible nature to the greatest extent under the 

 scorching sunbeams of the Torrid Zone. 



14. The Dog (Canis) spreads from the limit of 

 perpetual snow to the Torrid Zone; in such a 

 manner, that species of it occur in every degree of 

 latitude, in both Hemispheres : but the most nume- 

 rous and various kinds are natives of colder cli- 

 mates. The common Dog everywhere follows man.
