each answerable to the formula 0*' H” N O’. They can all three be resolved 
thus : — 
1. Atropine yields tropic acid and tropine (base) ; 
2. Bijoscijamine yields the same, i.e, tropic acid, and tropine (base) ; 
3. Hyoscine yields tropic acid, and pseudo-tropine, 
Note here, that in chemical parlance, Atropine is a compound of a base 
called Tropine and Tropic acid. Ladenburg calls the compound Tropeine."

Syn. : — Physalis Strainonifolia, Wall. 
Habitat -Central Himalaya, Nepal and Sikkim. 
An erect, glabvescent herb. Branches 3-6ft., sparingly 
divided, rusty-tomentose when young, later pnberulous or 
glabrate. Leaves 8 by 3 in., acute at both ends, ovate lanceolate, 
ultimately glabrate ; petiole fin., peduncles lin. Calyx in 
flower fin., in fruit attaining to 2 by lfin., lobes short, irregular. 
Fruit Calyx rather reticulated. Corolla If by fin., lurid yellow 
or greenish purple. Ovary 2 celled, 1-celled near the top. 
Capsule fin., lid 1-celled. 
Use : — A tincture of the leaves, in the proportion of one 
ounce to eight ounces of alcohol, administered produces dila- 
tation of the pupil. The subject demands further investigation 
(Ph. Inch) 
It has been examined by 8iebert. ( Archiv . dir Pharm. Feb. 20, 1890, 
p. 145.) From flowering plants he reports that be obtained, by fractional 
precipitation of an acidulated liquid with gold. chloride, a “ not inconsiderable 
quantity of hyoscyamine,” but no atropine or hyoscine, while from plants 
collected when the seed had ripened, only a very small quantity of atropine 
could be isolated under the same conditions and no hyoscyamine. The 
failure to detect hyoscine is thought to be possibly due to insufficiency of 
the material used. These results seem to indicate that the degree of develop- 
ment of the plant may have an important relation to the quantity and nature 
of the alkaloids occurring in it. (Pharm. Jo urn. Mar. 1st, 1890, p. 709.)
