We use the root's : our druggists keep them, and 

 they are the principal ingredient in that famous 

 powder, called, from its being volicd up into balls, 

 lapis contraverva. It is an excellent cordial and 

 sudorific, good in fevers, and in nervous cases ; 

 and against indigestions, colics, and weaknesses 

 of the stomach. It may be taken in powder or

 it is best in tincture. It is also an excclh-ni. in- 

 gredituit in b'tter tinctures ; and it is wonderful the 

 present practice lias i.e. I put it to that use. All 

 the old prejscribers of forms for these things, have 

 put some warm root into them ; but none is so 

 proper as this ; the most usual has been the galan- 

 gul, but (hat has a most disagreeable flavour in 

 tincture: the contraverva has ail the virtues ex- 

 pected to be found in that, and is quite unexcep- 

 tionable.

 breadth, they would be very like those of the oak ; 

 the flowers arc moderately large, and full of
