in snake-bites. The fresh juice is also employed in headache 
and colds (Long, Ind. Plants of Bengal). In Reunion, it is con-

Ohemi. com .— Tlio herb of L. zeylanica on distillation afforded a very- 
small quantity of essential oil. By boiling a decoction of the herb with 
soda solution a strong odour was given off, and on condensing the vapour, 
ammonia and a volatile alkaloid were detected in the distillate. The alkaloid 
was combined in the plant with an acid giving a green colour with ferric 
salts. The air-dried plant afforded 7 3 per cent, of ash (Pharmacog. Ind. Ill 
124).
