creases the danger of perforation. Mucilaginous and astringent 

 drugs are indicated (subnitrate of bismuth, silver nitrate), 

 also hemostatics including adrenalin or suprarenin (for dogs 

 30 drops of the 1% solution internally, repeated several times). 

 The administration of hydrochloric acid is contraindicated. 

 Carlsbad salt in larger doses may be employed with advantage, 

 since it neutralizes an excess in hydrochloric acid, diminishes 

 gastric secretion and aids in the removal of the contents of the 

 stomach. Obstinate vomiting must be met by narcotics (opium) .

9. Neoplasms in the Stomach. Tumores ventriculi. 



Occurrence. Tumors in the wall of the stomach are very 

 rare, and therefore, and because they are difficult to diagnosti- 

 cate, they do not have a great deal of practical significance. 



In the fore-stomachs of ruminants the omasum appears to be 

 the favorite seat of neoplasms; here there are found polypoid 

 tumors which attain a size of two lists and which ma}^ close up 

 the opening between reticulum and omasum. Similar tumors 

 are found more rarely in the reticulum. Sarcomata are likewise 

 found in the omasum, up to the size of a fist; nodular, tough 

 tumors, generally showing necrotic changes; these tumors are 

 found more rarely in the reticulum or rumen. Kitt saw a chon- 

 droma in the wall of the rumen of a calf. Finally the rumen of 

 cattle may contain ulcers as large as a hand, the base being 

 formed by thickened nodular masses of the wall of the rumen ; 

 such ulcers are probably due to carcinomatous neoplasms. 



Tumors are common in the stomach proper (the abomasum), 

 where they are found in the pylorus, the cardia, and the larger 

 curvature. In the horse there occur sarcomata and carcinomata 

 which, when growing in the stomach, may obstruct the cardia, 

 the pylorus and the duodenum. In the abomasum of cattle, epi- 

 thelial neoplasms are met with, such as adenomata, adeno-carci- 

 nomata, alveolar carcinomata, which undergo an early disinte- 

 gration ; further, diffuse lymphadenoid infiltration. Joest found 

 a tuberculoma in the stomach of a cow with general tuberculosis. 

 Eberlein observed a primary carcinoma in the stomach of a dog. 

 More rarely are lipoma, fibroma, myoma, found in the stomach; 

 similar to the latter is the circumscribed muscular hypertrophy 

 which is sometimes met with in the stomach of the horse. 



Symptoms. The presence of a tumor of any size in the 

 stomach disturbs its function on account of the destruction of
