Dr. Lemann found it useful in constitutional ophthalmia, and in pneumonia, in doses of a drachm, twice a day, with nitre. According to M. Moiroud, the dose for larger animals is from 1 to 2 dr. For smaller, 6 or 8 gr.

Sulphate of Copper

Blue Vitriol. Tonic and styptic. In doses of 1/2 dr. gradually increased to 2 dr. or more, daily, it is given in diabetes, farcy, etc. Small doses may be given in balls with gentian and ginger; larger doses in gruel. It has been thought useful in glanders; but Mr. Youatt says it is only proper in nasal discharges without fever. Dose for cattle, 1 to 2 dr. Sheep 20 to 40 gr. Rabbits (in sniffles), 1 or 2 gr. twice a day. Externally the solution is used for the foot-rot of sheep: and as a cleansing wash for foul ulcers in horses and cattle.

Tonic and astringent. Dose, 1 to dr. twice or thrice a day.

Cordials

Warm stimulating medicines, such as spices, and the aromatic seeds, fermented liquors and spirits, etc., which temporarily restore exhausted strength, revive the spirits, and rouse the system generally. The best modern practitioners condemn their indiscriminate employment as the source of much mischief. For cordial balls, etc, see Vet. Formulary. Coriander Seeds. A mild aromatic stimulant and carminative, used in cordial balls and drinks. Dose, 1/2 oz. to 1 oz.

Corrosive Sublimate

Perchloride, or Bichloride of Mercury. One of the most virulent of poisons. In small doses it is alterative and diuretic. It has been tried in doses of 2 to 5 gr., gradually increased to 10 or 20, in farcy and glanders, but rarely with lasting benefit. Externally it is used as a powerful caustic. A dilute solution is employed as a wash for scab and lice in sheep, but the practice is not free from danger. Applied to wounds in cattle it has proved as fatal a poison as when swallowed. The antidote for an overdose is white of egg, or milk, or the hydrated sulphuret (sulphide) of iron; with demulcent drinks.
