 occurs almost wholly in the cow, though a few cases have occurred

 constitutes the lining of the pouch, and lies in contact with the 

 contained limbs and head and neck. 



The diagnosis of this anomaly depends upon the anatomical re- 

 lations above mentioned. Usually the monster presents by its
