THE VETERINARY COLLEGE PHARMACOPOEIA. 627 
A good stimulating and detersive ointment. In its full strength 
it is an escharotic, but when mixed with double the quantity of 
lard it has been found very useful in some mangy affections, and 
particularly those of the eyelids of all domesticated animals. It 
is the only cure for psorophthalmia in the dog.

“Strong” with a vengeance, which no irritable sore or state of 
grease would bear for a moment, and which would eat into and 
corrode the healthiest wound. Besides, I doubt not a little the 
astringent properties of the ingredients. The astringent property 
of sulphate of copper I should at once deny. I might admit 
the bole to be a desiccative and a useful one; but this is a some¬ 
what different thing, and, in a standard pharmacopoeia, words 
should be applied in their right sense. 
As a desiccative application, and at the same time an astringent 
one, if I am permitted to keep the bole, and to substitute one 
ounce of alum instead of one pound of sulphate of copper, I 
should have a powder preferable to any ointment I could use in 
several varieties of grease. 
Solutions for Lotions. 
Solution of Alum. 
Alum...half a pound. 
Boiling water, seven pints and a half: stir till dissolved. 
I have no objection to this as a grease wash, except the relative 
quantities of the alum and the water. Seven pounds and a half 
of boiling water may dissolve ten pounds of alum, but when cold 
will not hold half a pound in solution. It is, however, true that, 
when the little extra alum is deposited, we shall have remaining, 
that which we want, a saturated solution of this salt.
