Take— Egyptiacum, compound tincture of myrrh, of 

 each four ounces : 

 Mix well in a bottle for use. 



Or, 



(RECIPE, No. 129.) 



Take— Corrosive sublimate, one drachm ; 



Blue vitriol, and sugar of lead, of each two 



drachms, all in powder : 

 Tincture of myrrh, four ounces ; 

 Spirit of salt (muriatic acid), two drachms : 

 Mix them together in a vial for use. 



Either of the mixtures will be found very pow- 

 erful in stopping the flow of the synovia, or joint- 

 oil : the former is the mildest of the two, and, in 

 most cases, will answer every purpose ; but when 

 the flow is of long standing, and the bone becomes 

 carious, the latter may be more powerful in cleans- 

 ing ulcers of this description. Medicines of this 

 class should never be used longer than until the 

 ulcer is thoroughly cleansed, after which the fol- 

 lowing styptic tincture will be sufficient.
