A TINCTURE OF THE FRESH RIPE SEED OF DATURA STRAMONIUM, L. 
Description.— This rank, glabrous, annual, bushy berb, grows to a height of 
from 2 to 4 feet. Root tapering, somewhat branched. Stem very smooth, subcylin- 
drical, green and succulent, at first bifurcating, then dichotomously branching, 
Leaves alternate, and at times opposite, upon the same plant, in reality more or 
less scattered; all more or less cordate at the base, but in many instances unequal, 
in this case one side of the base is prolonged decurrently along the upper side of 
the petiole. In outline the leaves are ovate, very irregularly sinuate, and laciniately 
toothed or angled; they are smooth, deep green above, pale beneath, and all the 
older ones are plentifully perforated by the ravages of worms. /nflorescence soli- 
tary in the forks of the branches; flowers erect, 2 to 4 inches long, raised upon a 
short rigid peduncle. Ca/yx tubular, prismatic, half-persistent, circumscissile, 7. ¢., 
separating transversely above the base, the upper portion falling away, the lower 
remaining persistent and forming in fruit a peltate border to the under side of the 
capsule; 4mé 5-toothed. Corol/a infundibuliform, delicate, creamy white, convo- 
lute-plicate in zestivation ;-4mé plaited, larger and spreading, 5-toothed ; sinuses 
long subulate-pointed. Stamens 5, included ; f/amenés long and filiform, inserted 
upon the tube of the corolla; azthers adnate, oblong and pointed. Sty/e slender, 
longer than the stamens, but not exserted ; stigma clavate, 2-lipped. /yw7t an 
erect, globose-ovoid and more or less quadrilateral, divergently echinate, 2-celled 
pod; pericarp coriaceous ; valves 4; placente 2, thick, projected from the axis into 
the middle of each cell, where each division becomes somewhat expanded into two 
placentiferous lines at the middle, thus rendering the pod in reality 4-celled, except 
at its apex. Seeds very numerous, rather large, laterally flattened horizontally, and — 
somewhat reniform; /es¢a crustaceous, scrobiculate-rugose ; eméryo much curved.

TF Expuxvopavtxov, strychnomanikon, referring to its causing madness. ees
