ON THE TOBACCO CLYSTER.

pentine, of each one ounce, should succeed it. Every time the 
dressings are taken off, the wounds should be gently washed 
with the following solution : — Take corrosive sublimate, in pow- 
der, one drachm, spirit of wine, brandy, or arrack, two table- 
spoonfuls, in order to dissolve it. To this may be added one pint 
of spring water. This treatment may be thought very severe ; 
but I have often been obliged to have recourse even to spirit of 
turpentine in the place of water, as their surfaces were so very 
insensible and obstinate. It must also be considered that the 
texture of the muscles of a horse are proportionably strong, and 
the strongest digestives employed for the human subject would 
be but emollients with the horse. 
If the course here recommended is correctly pursued, I can 
speak very confidently of its success, as many cases which I 
have had under my directions were, in every instance, perfectly 
cured in two, three, or four weeks, even when the ulcers were 
deep, numerous, and extensive; and if three-fourths of the cases 
supposed to be farcy were treated according to these directions, 
I am convinced a horse would very seldom be lost from what is 
usually termed by that name. 
EMINENT SUCCESS IN CHOLIC AND CONSTIPA- 
TION FROM THE TOBACCO CLYSTER AND THE 
SUBSEQUENT USE OF MERCURY. 
By Mr. William Percivall, M.R.C.S., Veterinary Surgeon 
First Life Guards. 
Many years ago, Mr. William Goodwin having a foal to treat 
labouring under constipated bowels, bethought himself, after 
ordinary means had proved abortive, of employing a clyster of 
tobacco-smoke, and the experiment proved a very happy one, 
for it was followed by the wished-for discharge of faeces. In later 
days, Mr. Simonds, then practising at Twickenham, now one of 
the Professors of the Royal Veterinary College, made similar 
experiments with an apparatus fitted to Read’s stomach-pump, 
and these likewise have turned out eminently successful. Still 
there are those amongst us who either doubt the efficacy of the 
tobacco-clyster, or who have not yet made it part of their prac- 
tice; and on such persons I would call for attention to a case under 
my care at the present moment. 
The mare, the subject of it, is eight years old, and in fat 
working condition. At half past eight o’clock of the morning of
