ViNEGiiii is a very useful application for sprains and bruises. Equal 

 parts of boiling water and cold vinegar will form a good fomentation. 

 Extract of lead, or bay salt, may be added with some slight advantage. 

 As an internal remedy, vinegar is rarely given, nor has it, except in verv 

 large doses, any medicinal power. The veterinarian and the horse-owner 

 should manufacture their own vinegar. That which they buy may con- 

 tain sulphuric acid, and pungent spices, and irritate the inflamed part to 

 which it is applied. 



Wax. — The yellow wax is used in charges and some plasters to render 

 them less brittle. 



Zixc. — The impure carbonate of zinc, under the name of Calamine 

 Poicder, is used in the preparation of a valuable healing ointment. Five 

 parts of lard and one of resin are melted together, and when these begin to 

 get cool, two parts of the calamine, reduced to an impalpable powder, are 

 stirred in. The calamine is sometimes sprinkled with advantage on cracked 

 heels, and superficial sores. 



The sulphate of zinc, White Vitriol, in the proportion of three grains to 

 an ounce of water, is an excellent application in opthalmia, when the 

 inflammatory stage is passing over; and quittoris most successfully treated 

 by a saturated solution of white vitriol being injected into the sinuses. A 

 solution of white vitriol of less strength forms a wash for grease that ia 

 occasionally useful, when the alum or blue vitriol docs not appear to succeed.
