REVIEW OF MOIROUD’S 
Mixed with the white of an egg, it forms a diseutient liniment 
for sprains and saddle-galls. Burnt alum is a slight escharotic, 
and proper to cleanse sanious ulcers, and to destroy fungous ex¬ 
crescences. 
Sulphate of Zinc. This is a powerful styptic, either ap¬ 
plied externally, dissolved in water or in some fluid that can in¬ 
crease its effect, in the form of lotion and injection. It is fre¬ 
quently used as a collyrium. Administered internally, it excites 
vomiting in the carnivora: but it is rarely exhibited for that pur¬ 
pose. In doses of an ounce it acts as a poison, and destroys 
life. It poisonous action is most evident when introduced under 
the skin. Two drachms applied to the cellular tissue on the in¬ 
side of the thigh of the dog, have destroyed the animal in five or 
six days, and deep ulcerations have been found in the stomach, 
and principally about the pyloric region. 
The oxide of zinc is astringent and desiccative employed exter¬ 
nally, and useful in chronic ulceration and obstinate ophthalmia. 
It has been said to have been used with advantage in epilepsy, 
and other nervous affections; but its power in these diseases is 
not generally acknowledged. 
The impure oxide , commonly called tutty , is employed as an 
anti-ophthalmic. 
Acetate of Lead. This is the astringent most frequently 
used as an external application by veterinarians. It is a resolvent 
and desiccative in burns and many other cutaneous inflamma¬ 
tions, and in engorgements of the cellular tissue, sprains, contu¬ 
sions, and grease. Injected into the nasal cavities, it arrests 
chronic discharges, and cleanses glanderous ulcers. It is gene¬ 
rally used dissolved in a great quantity of water, but sometimes 
it has been employed almost undiluted. A little alcohol is often 
advantageously united to it. 
Incorporated with lard and wax, it is the basis of many desic¬ 
cative ointments. 
The carbonate of lead is employed for similar purposes. 
Except used with considerable discretion, it cannot be employed 
internally without danger. It acts at the same time on the mu¬ 
cous coat of the intestine and on the nervous system, and pro¬ 
duces that species of empoisonment denominated the lead colic . 
Lime. Quick lime is sometimes employed as a caustic, to re¬ 
press fungous growths. Lime, however, is chiefly used in com¬ 
bination with water, to cleanse foul ulcers, and dry up chronic 
discharges. It is injected with advantage into the nasal cavities, 
in ulceration and chronic gleet of the pituitary membrane. Lime- 
water has been given with benefit in the hoove of cattle. Some 
practitioners have thought it useful in glanders and farcy : it
