 is used with resin, the application being made at first with vine- 

 gar. "With lime and vinegar, it is used as a liniment for stings 

 inflicted by serpents, as, also, for ulcerations, whether phage- 

 daenic, putrid, or serpiginous; in cases, too, of dropsy, it is 

 employed both internally and externally, beaten up with figs. 

 Taken internally as a decoction, in doses of one drachma, with 

 rue, dill, or cummin, it effectually removes griping pains in 

 the bowels. An external application of it, with oil and vine- 

 gar, is highly refreshing to persons exhausted with fatigue ; 

 and it is equally beneficial for shudderings and coldshiverings,

 upon jaundice, more particularly when it is administered to

 administered in a ptisan. Flower of nitrum, used in combi-
