56 PICTURE OF ORGANIZED NATURE. 



of Lybia and the Senegal, but casts off its wool. 

 The spread of these genera extends, of course, as 

 far as the warm climates ; but their native country, 

 in their wild state, is the colder half of the Tem- 

 perate Zone. 



11. The Antelope (Antilope} is met with, in the 

 greatest numbers, in the warmer half of the Tem- 

 perate Zone; but extends as far as the Warm Zone : 

 they approach very near to the snow-line, but do not 

 reach it. Of these, the Chamois (Antilope rupicapra) 

 inhabits the Alps ; but descends, like the migratory 

 birds, during the winter months, towards the dwellings 

 of man : the Antilope Scythica migrates in a similar 

 manner. In the Torrid Zone are the Gazelles: they 

 are, principally, inhabitants of forests. 



12. The Musk (Moschus) inhabits, for the most 

 part, the lofty mountains of the Temperate Zone : for 

 instance, the common Musk is to be found in China 

 and Thibet. In those countries they nearly reach the 

 snow-line ; though some species, as the Pigmy Musk 

 {Moschus pygmceus), extend to warm countries. The 

 native country of these animals appears, therefore, to 

 coincide with the plain level in the 50th degree N.L. ; 

 from whence they extend to the grassy regions on 

 one side, and to the warm countries on the other.
