 dealt with according to their specific nature in each several case. 

 When any definite cause of this kind has been overcome the per-

 employed with excellent effect. 



CESOPHAGEAN TUMORS. 



Forms of neoplasm in gullet of horse, ox, sheep, pig, dog. Symptoms : 

 dysphagia : eructation : vomiting ; bloating ; cough ; dyspnoea ; stertor ; 

 foetor ; palpitation. Treatment. 



These have been often noticed in the lower animals. In the 

 horse have been noticed melanoma (Olivier, Roll, Kopp, Besnard,

 swine from gongylonema, and in sheep from filaria (Harms) 

 or spiroptera (Zurn). 



In pigs ; fibroma is met with in the walls of the gullet 

 (Raveski) and in dogs fibroma, papilloma, and the tumors of
