INDIAN M EDICINAI. PLANTS. 
linear-lanceolate or slightly obovate, much tapering to base- 
rather suddenly accuminate, subacute, glabrous, pale beneath, 
rather thick, venation pellucid, lateral veins numerous, horizon- 
tal, connected by an intermarginal one. Petiole 1-l^in. long. 
Flowers large, on a stout erect peduncle, white, with throat yellow, 
sweet scented, in ample terminal cymes or flat topped panicles; 
bracts |-lin. long, oblong, acute deciduous. Calyx segments f-fin. 
linear-oblong, acute, recurved, glabrous, deciduous. Corolla-tube 
•fin., lower third narrow, upper part dilated, throat nearly 
closed by 5 pubescent projecting wings ; lobes lin. Ovule, obtuse, 
oblique; filaments very short (Trimen!. Ovary of 2 distinct 
carpels united by a single style. Fruit (from the abortion of 
one carpel) a drupe, 2-4iu. long, flattened on one side, with a 
fibrous endocarp. Seed usually one, oily, albumen 0 (Brandis). 
Uses: — The whole plant is full of an acid milky juice- 
Emetic and purgative properties are assigned to the milky sap 
and to the leaves, but their use is to be condemned (Ph. Ind ). 
The nut is narcotic and poisonous. The green fruit is 
employed to kill dogs (Balfour . 
The fruit combined with Datura is a part of remedy given 
by native physicians for hydrophobia (Pharamcographic Indica, 
Vol. 11, p. 410. 
The bark is purgative (’A att). 
The kernel of the fruit is an irritant poison, producing, 
when taken internally, vomiting and purging, soon followed by 
collapse and death (Surgeon-Major Houston, in Watt’s 
Dictionary.) 
CerebHn C 17 H 40 O a occurs in the seeds. It forms colourless, odourless crys- 
tals, with a bitter taste, turns yellow at 180—185°, and melts at 191—192° (corr.). 
Itdisparts of the solvent at 16-21°,— Chloroform 8'83 ; alcohol 90 per cent. 12'43,

following values of speciflc rotation : [o]„ ; in 90 per cent, alcohol — 74'61°; in 
ether— 6476° ; in chloroform, 74’82°; in acetic acid — 80'8l°. Analysis and mole- 
cular weight determinations lead to the formula C, 7 H 04 O 8 ; but its properties 
show that it is not identical either with the taughinin of Arnaud or with the 
the thevetin of De Vrij. It exhibits the following colour reactions : I. Yellow
