in such conditions, contains: laudanum, 1 part; Goulard's 

 extract, 4 parts ; and oil, glycerin or water, 16 parts. The 

 " white lotion " of vet&rinary medicine is made by adding 3 

 drachms each of lead acetate and zinc sulphate to a pint of 

 ■R-ater. It is a favorite astringent, sedative and antiseptic 

 application, for strains, bruises, scratches, bursitis and teno- 

 synovitis in horses. Compresses soaked in it are bandaged 

 to the part. Also as an injection in urethritis, and exter- 

 nally in balanitis of dogs. The stronger solution of lead 

 subacetate should not be employed extensively on raw 

 surfaces or mucous membranes undiluted. The diluted 

 Solution of lead subacetate may be used as an injection for 

 leucorrhoea. Lead acetate should be diluted with 20 to 40 

 parts of vinegar or water. Lead acetate is not suitable for 

 «ollyria, if there is any ulceration of the cornea, because a 

 permanent film may be deposited and obscure the sight. 

 Lead iodide, in 10 to 20 per cent, ointment with petrolatum, 

 has proven of service in aiding resolution of induration or 

 caked condition of the udder in acute mammitis, if applied 

 twice daily with thorough massage, before suppuration has 

 set in. 



Uses Internal. — Lead acetate is serviceable in the treat- 

 ment of diarrhcea, dysentery, and hemorrhage from the 

 stomach and bowels. It is frequently prescribed in these 

 diseases with opium, but should not be used for a long 

 period.
