Compound Infusion of Tobacco. 
Infusion of tobacco.two pints 
Oxymuriate of mercury; muriatic acid, each .. one drachm 
Dissolve the oxymuriate in the acid in a glass mortar, and add to 
it the infusion of tobacco. 
I am not aware of any injurious decomposition here, and we 
have a more efficacious lotion for mange in the horse, and parti¬ 
cularly in cattle. To the dog it is more destructive than the sim¬ 
ple infusion; and it does not seem to be improved as an applica¬ 
tion for sheep. 
Injections. 
Injection for fistulous Sores . 
Oxymuriate of mercury...one drachm 
Muriatic acid.--..two drachms 
Water, or rectified spirit - .five drachms.—Mix. 
To this, for indolent ulcers and fistulse generally, there can be 
no objection. It may be alternated with the solution of sulphate of 
zinc, to which, however, it is, on the whole, somewhat inferior. 
Liniments. 
Liniment for Canker , fyc. 
Sulphate of copper -.-.. twelve ounces 
Acetic acid ....six ounces 
Treacle ..........three pounds 
Melt these together, and when nearly cold mix. 
fi 
There is a little ambiguity here. The meaning probably is, 
that the treacle and the acetic acid should be melted together, 
and the blue vitriol, in fine powder, added when the syrup was 
nearly cold. I confess that I do not understand the object in¬ 
tended to be accomplished; for we have, after all, an acidulated 
syrup, holding the sulphate of copper in solution or suspension ; 
and I am yet to learn what advantage I gain by this: however, 
let it pass. The sulphate of copper, although not the bekt, is 
not a bad application for canker, and the vinegar and the treacle 
can do no material harm; while this mav be said in their favour, 
that we get rid of a greasy application, which is rarely beneficial, 
and sometimes injurious in canker. 
It is a thousand times better than the prescription which fol¬ 
lows, and which is also recommended for canker. 
Yerdigrise...nine ounces 
Alum powdered .. six ounces 
Treacle.-.. one pound and a half 
Boil together, and add sulphuric acid three ounces.—Mix.
