soluble in cold alcohol, and very soluble in boiling alcohol; it 
colours the saliva yellow. It melts at 238° C., and is decom- 
posed; heated with strong sulphuric acid it forms Harmaline- 
sulphuric: acid, which on the addition of water, gives a fine 
blue fluorescence. Treated under pressure with fuming 
hydrochloric acid it yields Hermatol, which forms orange-red 
crystals sparingly soluble in water. This solution is strongly 
fluorescent and is probably identical with the yellow colouring 
matter of the seeds. Harmaline forms with acids crystallizable 
yellow salts soluble in water, to which they communicate a 
remarkable fluorescence. UHarmine which exists in the seeds, 
is also obtained by oxidizing Harmaline with nitric acid. It 
crystallizes in colourless needles almost insoluble in water and 
very little soluble in cold alcohol or ether; it fuses at 256° C., 
and is partly sublimed and partly decomposed. Biking 
hydrochloric acid converts it into Harmal, the acid solution of 
which is fluorescent. Oxidised by means of chromic acid it 
yields Herminic acid, C19 H® N* 0%, which crystallizes in 
silky tufts, 
Commerce.—Hurmal nocd i is imported from Persia, but the 
plant has been introduced into India by the Mahometans, and 
in some places has run wild. In Southern India Henna seeds 
Be under the name of Jswand are used as a substitute for this
