 has remarked, is sometimes found as a tem- 

 porary state of the human stomach;* while, 

 in other animals, it is the natural and per- 

 manent conformation. The Rodentia furnish 

 many examples of this division of the cavity 

 into two distinct portions, which exhibit even 

 differences in their structure : this is seen in the 

 Dormouse, (Fig. 300) the Beaver, the Hare, the 

 Rahhit, and the Cape Hi/rax, (Fig. .307). The 

 first, or cardiac portion, is often lined with 



cuticle, while the lower portion is not so lined ; 

 as is seen very conspicuously in the stomachs of 

 the Solipeda. The stomach of the Horse, in 

 particular, is furnished at the cardia, with a

 the state of partial contraction here described.
