 countries, but would in a few years degenerate ; their 

 strength and their patience would forsake them ; and, in- 

 stead of enriching, become a burden to their keepers; uses 

 to which this animal is put among the Arabians ; its educa- 

 tion ; it has a fifth stomach, as a reservoir, to hold a greater

 finds itself pressed with thirst, it throws up a quantity of 

 this water, by a simple contraction of the muscles, into the 

 other stomachs ; travellers, when straitened for water, have

 one eye seems to look directly forward, while the other 

 looks backward ; and one looks upward, while the other re- 

 gards the earth, v. 317- 



Camelopard described; dimensions of a young one; inhabits 

 the deserts of Africa ; no animal, from its disposition, or its 

 formation, less fitted for a state of natural hostility; it lives 

 entirely upon vegetables ; known to the ancients, but rarely 

 seen in Europe ; often seen tame at Grand Cairo in Egypt ;
