VALEUIAN. IVc dried root is employed 

 by medical practitloncvsj in spasinodic anvl 

 nervous complaint--, but t^iere is no disease

VERDIGRIS. The rust of Copper. It 

 is made in wine countries, by burying thin 

 copper-plates in the refuse parts of the 

 grape, after the juice has been pressed out. 

 It is employed externally as a mild caustic, 

 or detergent, and is frequently mixed with 

 common tmpentine, or ointments, for the 

 same purpose. (See Detergents, Pharm.) 

 When verdigris is dissolved in distilled 

 vinegar, and chrystallized, it becomes con- 

 siderably stronger, and will be found an ex- 

 cellent remedy for quittors. (See the Com- 

 ■ pendium.) In this state it is called chrystal- 

 lized, or distilled x;<?raV^m. Common verdi- 

 grishas been recommenucd a^ a remedy for 

 the farcy ; but I have never seen it do any 

 good in that complaint, though I have seve- 

 ral times given it a trial. 



It has been fairly tried in the glanders : 

 half an ounce was piven daily for a conside- 

 able time, but it had no effect on the disease, 

 nor did it occasion any inconvenience to the
