290 MERCURIAL LINIMENTS 



ointment, and forty died, with symptoms of short breathing, 

 a peculiar grunt indicative of pain, and drooping head 

 (Taylor). The maximum amount of the strong ointment to 

 be used for horses is two ounces, for cattle an ounce, for 

 sheep half an ounce, for dogs thirty grains to a drachm. 

 For topical purposes a second dressing, if required, should 

 not be applied for two or three days. 



LINIMENT OF MERCURY. Linimentum Hydrargyri. 

 MERCURIC OLE ATE. Hydrargyri Oleas. 



One part of mercury ointment, one-third part of strong 

 ammonia solution, and one and a half of camphor liniment, 

 thoroughly mixed, constitute the B.P. liniment. Its effects 

 are similar to those of the ointment. Two liniments suitable 

 for persistent scaly skin diseases, enlarged glands, and chronic 

 indurations are subjoined : 



Mercurial ointment, 2 ounces. Mercurial ointment, 2 ounces. 



Camphor, . . 1 drachm. Creosote, . . 1 drachm. 



Oil of tar, . . 4 ounces. Liquor ammonise, 2 ounces. 



Linseed oil, . . 4 ounces. Linseed oil, . . 6 ounces. 



The oleate is prepared with one ounce mercuric chloride, 

 two ounces hard soap, one drachm oleic acid, and a sufficient 

 quantity of distilled water. One part mixed with three 

 parts of benzoated lard is diffusible and penetrating. It 

 promotes absorption, and, used repeatedly, acts as a counter- 

 irritant. It is applied in articular inflammation, exostoses, 

 indurations of the udder, and other glandular and indolent 

 swellings. Diluted solutions destroy ringworm and favus, 

 and are also fatal to animal parasites. 



MERCURIAL PLASTER. Emplastrum Hydrargyri. 



Is made with olive oil, 56 grains ; sulphur, 8 grains ; mer- 

 cury, 3 ounces ; and lead plaster, 6 ounces. The olive oil is 

 heated, and the sulphur gradually added until they unite. 

 With this mixture triturate the mercury until globules are 

 no longer visible ; then add the lead plaster, previously 

 liquefied, and mix thoroughly (B.P.). This plaster is occa- 

 sionally used as a stimulant for glandular and chronic 

 enlargements, wind-galls, and other bursal swellings.
