62 THE DISEASES AND DISORDERS OF THE OX. 



transversely between the posterior surface of the diaphragm and 

 the anterior extremity of the left sac of the rumen. It derives 

 its name Reticulum from the net-like {retis, a net) character of 

 its internal coat, and it is situated under the termination of the 

 gullet. It is about one-sixth part of the size of the paunch, to 

 which it is attached in front. The interior of this second stomach 

 communicates with the left sac of the paunch ; and it commu- 

 nicates with the manyfold (as shown in the illustration) by an 

 opening eight or ten times smaller than the opening into the 

 paunch. It is found that the foreign bodies so frequently 

 swallowed by ruminants are usually lodged in the honeycomb.

The opening into the manyfold is connected by a groove or 

 kind of gutter, which appears to continue the gullet into the 

 interior of the stomach. 



The anterior surface of the reticulum adheres to the centre of 

 the diaphragm by means of cellular tissue, and its posterior 

 surface is united to the anterior extremity of the rumen. The 

 inferior convex curvature is situated in the epigastric region, 

 while the superior curvature which is concave comes partly into 

 relation with the small curvature of the psalterium. The left 

 extremity of the reticulum is separated from the rumen by a 

 fissure, in which runs the inferior artery of the reticulum. The
