Sub-family c. Camelina. 

 CAMELUS. (Gr. Ka/^Xoe, a Camel.) 



Arabicus (Lat. Arabic), the Camel. 



The Camel forms the principal wealth of the Arab : without 

 it he could never attempt to penetrate the vast deserts where 

 it lives, as its remarkable power of drinking enough water at 

 one draught to serve it for several days enables it to march 

 from station to station without requiring to drink by the 

 way. The peculiar structure of its stomach gives it this most 

 useful power. In its stomach are a great number of deep 

 cells, into which the water passes, and is then prevented from 

 escaping by a muscle which closes the mouth of the cells. 

 When the Camel feels thirsty, it has the power of casting some 

 of the water contained in these cells into its mouth. The 

 habits of this animal are very interesting. A recent traveller, 

 the Rev. J. H. Pollen, most kindly forwarded to me the fol-
