treatment of canker of the ear in dogs (gr.x to §i.), or as "white lotion" 

 (see plumbi acetas), in this affection. 



In diseases of the feet, as in canker of the horse, equal parts of zinc, 

 copper and iron sulphates with 5 per cent, carbolic acid and vaseline q. s. 

 to make a paste, are of value. 



The salt is likewise serviceable as a stimulant and astringent solution 

 (gr.ii.-v. to §i.) in moist eczema, ulcers, atonic inflammations of mucous 

 membranes, balanitis and urethritis in dogs, and leucorrhea. 



Zinc carbonate is a much milder astringent than zinc sulphate or 

 acetate. The impure carbonate (calamine) is an ingredient of the popular 

 astringent and antiseptic "pink ointment" of veterinary medicine used 

 for the cure of "scratches" in horses.

The lard and wax are first melted together and then the other ingre- 

 dients are stirred in. Calamine in the form of a lotion is a more cleanly 

 application for house dogs and pets than ointment or paste. The follow- 

 ing is useful in dermatitis, erythema and moist eczema attended with 

 itching. The carbolic acid may be omitted when the lotion is applied 

 over a large surface to avoid poisoning by absorption or from the acid 

 being licked off by the patient.

Zinc is used externally in the form of a dusting powder, ointment or 

 paste. In eczema, erythema and scratches, the zinc oxide ointment is 

 valuable and can be combined with carbolic acid (gr.x to ji-) or creolin 

 (5 per cent.) to great advantage, when itching is a prominent symptom. 

 Still better than zinc ointment is the addition of calamine 1 part to 7 

 parts of ointment; or a paste containing zinc oxide, starch and vaseline.
