was tilled from the duodenum moderately with 95 per cent, alcohol. 

 The omentum and mesentery were then carefully removed ; the 

 pancreatic and hepatic ducts isolated for a short distance ; the chol- 

 ecyst carefully separated from the liver ; then the O3sophagus was 

 separated from the diaphragm and ligatured about 2 cm. cephalad 

 of it. The duodenum was also ligatured, and then the whole was 

 put into 95 per cent, alcohol for two days. The ventral portion was 

 then removed, as shown, with a sharp scalpel, and the contents 

 washed out.

735. Stomachus, az. Stomach (Fig. 79, 714). Demonstrate 

 the following : (A) The abdominal oesophagus. Turn the left lobe 

 of the liver cephalad, and the abdominal O3sophagus will be seen 

 emerging from the diaphragm and entering the cephalic or cardiac 

 end of the stomach. 



From the nearly cephalo- caudal direction of the dorsal part of 

 the diaphragm, the dorsal side of the cardiac end of the stomach is 

 applied closely to it, and hence there is an abdominal oesophagus 

 only on the ventral side. 



(B) The stomach as a whole is pear-shaped and curved upon 

 itself. The curvatura major, or great curvature, faces sinistro- 

 caudad, and the great omentum is attached to it. The curvatura 

 minor, or lesser curvature, looks dextro-cephalad, and there is 

 attached to it the lesser omentum. 



The larger or cardiac end is next the diaphragm and receives the 

 oesophagus. The pyloric or smaller end is curved sharply upon 

 itself, and is partly concealed on its ventral side by the liver. 



(C) Pylorus or pyloric valve (Fig. 79). This is between the 

 stomach and small intestine. It usually appears as an annular con- 

 striction, and is firm to the touch. The pylorus in the cat, as in 

 man, is a ring-like fold of mucous membrane and a sphincter mus- 

 cle formed by an increase in thickness of the general layer of 

 circular muscular fibers of the alimentary canal.
