GASTRIC TYMPANY

 and cannula on the stomach, and the passing of an 

 oesophagus-tube. 



I think that" most veterinarians will 

 agree with me in saying that puncturing 

 the stomach is not without a grave ele- 

 ment of danger, and therefore not to be 

 advised. However, should tympany of 

 the intestine also be present, the opera-

 and afterwards advocated by General 

 Smith. That it would afford relief if 

 introduced no one would attempt to 

 deny. As General Smith's writings,

 the veterinary surgeon must either ex- 

 periment in that line himself, or wait 

 until someone has further improved upon 

 this mechanical means of treatment.^

^ Since the above was written I have received 

 letters from two American practitioners, the 

 contents of which are at any rate interesting in 

 this connection. I give them here : 



Dr. A. T. Everett, of South Omaha, Nebraska, to whom I am 

 indebted for Fig. 7, says : ' With reference to the oesophagus-tube, 

 which you say is as yet "imperfect," I enclose you a cut of a 

 stomach-tube invented by Mr. D. O. Knisely, which seems to give
