a. First cavity, called the paunch. 



b. Second ditto, the honeycomb bag. 

 e. Third ditto, the many-plies. 



d. Fourth ditto, the reed, or renuet. 



e. A portion of the oesophagus, showing its connection with the stomach. 

 /. The pylorus, or opening into the intestines. 



The interior of those cavities present some remarkable 

 differences in point of structure, which, in the present 

 work, can only be alluded to in a very general manner. 

 For a particular account of the internal anatomy of 

 these complicated organs, the reader is referred to the 

 interesting work on ' Cattle/ by W. Youatt.
