THE COLLEGE VETERINARY PIIARMACOPCEIA. 
This is the iEgyptiacum, with all its obsolete and unchemical 
nonsense—the round-about, expensive, unscientific way of ob¬ 
taining a syrup of blue vitriol, and in the highest degree dis¬ 
graceful to an institution like the Royal Veterinary College. 
There used, in my time, to be a liniment in the Pharmacopoeia, 
better than either of these. It was more active, and more likely 
to be serviceable in a complaint that would not yield to child's 
play. It consisted of sulphate of copper, alum, and vinegar, 
with an additional quantity of sulphuric acid. It was a com¬ 
pound with a vengeance,—blue vitriol, and alum, and free acetic 
acid, and free sulphuric acid; but there was no chemical blunder; 
and it was a powerful application to keep down the fungus. We 
apprehend, however, that these liniments are discarded by most 
experienced practitioners; and that for the destruction of the fun¬ 
gus, and the formation of healthy granulations, the knife, the 
chloride of antimony, and firm and equable pressure, are alone 
resorted to. 
Tar Liniment. 
Oil of tar (rectified) 
Common oiJ or sperm oil, each...one pint.—Mix. 
As a dressing for wounds, or for the feet, and particularly as 
suppleing the horn, and preserving and restoring hard and brittle 
feet, this liniment is excellent. 
Turpentine Liniment. 
Oil of turpentine, and olive oil, each.. ...one pint.

This is a very good digestive liniment, and forms a useful 
sweating blister for old strains, or callous formations. 
» Mixtures. 
Thrush Mixture. 
Liquid tar_-_-___.. four ounces 
Sulphuric acid ... one drachm and a half.—Mix. 
By liquid tar is meant, the vegetable tar extracted from the fir 
in the act of burning. It is the pix liquida of the druggist; and 
the'merest tyro knows that when sulphuric acid is mixed with it, 
a sudden, and in some cases violent, decomposition takes place. 
The black oil of the farriers is the result of the partial combus¬ 
tion of the turpentine by its union with the acid. If the tar were 
previously good for any thing in the treatment of thrushes, it is 
now strangely changed by the union of the oxygen of the acid 
with its carbon and hydrogep; and if the sulphuric acid were 
previously good for any thing, it, too, must be changed in its pro¬ 
perties and effects, when it becomes a mere sticky mass, an 
oxygenized resin or bitumen.
