Method of stabbing Hoven Cattle, to discharge the rari- 
fied air from the stomach, when they have been over- 
fed with moist clover grass. Communicated by Mr. 
WW. Wallis Mason, of Goodrest Lodge, near War- 
wick. From Trans. Soc. Arts, London, vol. 26. 
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 ~ 
atube, 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.
