bent, and the cotyledons are more pointed. The horny brown- 
ish albumen is translucent, very hard, and difficult to split- 
The whole seed swells considerably by prolonged digestion in 
warm water, and has then a heavy, earthy smell. The beans 
are intensely bitter, and highly poisonous. 
Microscopic structure.—The hairs of the epidermis are of an 
analogous structure, but more simple than in nux-vomica. 
The albumen and cotyledons agree in structural features with 
those of the same parts in nux-vomica. 
Chemical composition.—Pelletier and Oaventou (1819) found 
the seeds to contain the same constituents, though in different 
proportions, as nux-vomica ; they stated the yield of strychnine 
(still containing brucine) to be 1-4 per. cent. Geissler (1837) 
likewise found 1°5 per cent. of this alkaloid. F. F. Mayer 
(1863), on assaying ignatia with his solution, obtained from 2 
troy ounces of the seeds 4°5 grains of strychnine and 13°73 
grains of brucine, which correspond to 0°52 per cent. of the 
former and 1°43 per cent. of the latter. The dried seeds yield 
1:78 per cent. of nitrogen, indicating about 10 per cent. of 
albuminoids. (Pharmacographia.) 
Commerce.—The seeds sometimes reach India from the 
East via Singapore, or are ees from Europe. Value, 
extremely variable.
