IMPREGNATED WINES. 



Although some of the wines are obscurely ordered by their mere 

 colour and country, of which, however, many sorts are sold ; yet 

 this is of less consequence, as the retailers usually employ raisin 

 or currant wine instead of more expensive foreign ones. The 

 P. L. 1745 was the only one that determined the exact sorts the 

 college wished to have employed, until 1809, when the college 

 rejected all wine but Sherry, to which alone they restricted the 

 generic term of vinum, as the Pharmacopoeia of the United States 

 has restricted the term vimim to Teneriffe. In the present Phar- 

 macopoeia they have changed all the wines into weak tinctures, 

 but left their names unaltered.
