Six drams of sulfate of zinc and one ounce of 

 acetate of lead, dissolved in a quart of water, is an ex- 

 cellent antiseptic and astringent, and is extensively used 

 in veterinary practice as "white lotion." It should be 

 well shaken before using. It is poisonous when taken 

 internally. An excellent antiseptic ointment for use 

 on sores or irritated conditions of the skin is made by 

 combining one part of zinc oxid with about five parts 

 of fresh lard or vaseline. 



These antiseptics, as already said, possess secondary

Antiseptics are sometimes mixed with some sticky

 used for dusting on wounds or sores ; the objections 

 are its odor and expense. Pulverized boric acid and 

 common borax are good antiseptics that can be used in 

 this way. Boric acid can be used in a solution of twenty 

 grains to one ounce of water, and makes an excellent 

 wash for the eye, for the mouth or other cavities, as it
