APP. — TINCTUUE OF ASSAFCETIDA, &C. 291 



The quality of this tincture in a great measure 

 depends on the strength of the spirit ; if that is 

 not good, it will not be of much service. Its use 

 will be found in a number of places in this work. 



TINCTURE OF ASSAF(ETIDA. 



Take — Assafoetida, four ounces; 



Rectified spirit of wine, one quart : 

 Digest for seven days, and strain. 



This is a useful tincture to mix along with other 

 dressings for wounds, to prevent the flies from 

 teasing the animal in the summer season. As an 

 internal medicine its use will be seen in different 

 parts of this book. The gum is likewise used in 

 balls, with other articles, for several diseases. 



SOAP LINIMENT, (OR OPODELDOC.) 



Take — Soap, in shavings, two ounces ; 



Oil of rosemary, half an ounce ; 



Camphor, one ounce ; 



Rectified spirit of wine (the strongest that can 

 be bought), one pint : 



Digest the soap in the spirit of wine till dis- 

 solved ; then add to the liquor the camphor 

 and the oil, shaking them well together. 



Its use is chiefly as an external application in 

 strains, bruises, &c. See (No. 63, p. 91), and
