ANATOMY OF THE STOMACH. 



The most interesting and important anatomi- 

 cal peculiarity of the camel is that cmioiis struc- 

 ture by which he is enabled to take in at once,

 more recent naturalists, that the stomach of the 

 camel is not only able to retain for many days 

 water swallowed by the animal, but that it pos-
