Method of stabbing Hoven Cattle^ to discharge the rari- 



Jied air from the stomach, when they have been over^ 



fed xvith moist clover grass. Communicated by Mr,

Gentlemen, 



I beg leave to lay before you a trocar and canula 

 for the relief of cattle, when gorged or hoven. Since I 

 have introduced it, it has been used with the greatest 

 success, having, in every instance tried, been proved a 

 safe, easy and effectual remedy. I consider it will not 

 be necessary for me to detail the dangerous conse- 

 quences arising from cattle being hoven, as it is well 

 known, that the public are annually deprived of num- 

 bers of valuable cattle by this disorder. I am inclined 

 to offer it as an instrument superior to that for which 

 the society granted a premium in the year 1796 ;* as I 



* The instrument for which the Society of Arts rewarded 

 the inventor by a premium of fifty guineas in 1796, was not 

 a tube, but consisted of a cane six feet long, having a knob at 

 one end, which was to be pushed down the throat of the ani- 

 mal into the paunch, and thus to give free passage to the air 

 extricated by the clover^ The flexible tube mentioned was in- 

 vented by Dr. Monro of Edinburgh In 1795, and consisted 

 of iron wire twisted round a rod of polished iron ; the wire 

 after being taken off the rod, is to be covered with leather.
