As the resorcin is not soluble in albolene or by heat we dis- 

 solve the resorcin in a very small amount of alcohol, rul^bing 

 slowly in a mortar and then add the required amount of the al- 

 bolene and a clear mixture is the result.

In this case dissolve the menthol in the albolene by slow heat- 

 ing. Dissolve the resorcin as in the previous prescription and 

 then mix together and a clear solution results. 



Note. — It is understood that it is the duty of the pharmacist in 



every instance to communicate with the physician and inform him 



of his methods in dispensing.

The adrenalin is not miscible with mineral oils therefore use 



the adrenalin inhalant which is an oily solution of some strength 



and dissolves easily in the oil. Instead of the salt of cocaine use 



the pure alkaloid which is soluble in liquid petrolatum by heat. 



Put the menthol into the bottle while the liquid petrolatum is 



still warm; it will therefore dissolve and the entire mixture is 



clear. 



I^ 5. Mercury Salicylatis in Albolini 20% 

 Sig. To be used for injection. 



Mercury Salicylate we all know is not soluble in albolene nor 

 does it remain in staple suspension for any length of time. The 

 precipitate is thick, heavy, and very difficult to agitate and as this 

 is one of the most important mixtures with a very strong and 

 powerful drug and used for deep injections a uniform and easily 

 subdivided solution must be made. In order to produce this effect 

 emulcify the salicylate of mercury with the albolene by the ad- 

 dition of JX% of Lanolin Anhydrous.
