Anethum. 
(Peucedanum graveolens, Benth.) 
A distillate from Indian dill seed is reported to have shown 
besides a difference in the aroma, a considerable variation in chemi- 
cal composition from oil distilled from German seed. From the 
distillate from Indian seed there was a remarkable separation of a 
constituent heavier than water, the nature of which has not yet been 
determined. The specific gravity reached 0-970, and the optical, 
rotation +41° 30’. German dill oil consists of limonene and carvol 
and has an average specific gravity of 0-910, (Ber, von Schimmel

Dorema Ammoniacum. 
Under the name of 522 (bury) we have received from Afghanistan 
the root of this plant. 
Anisun. 
Under this name we have received Hemlock fruit from Afghanistan, 
ARALIACEAE, 
Panax Ginseng. 
Davydow (Pharm, Zeitschr, f. Russl., 1899, pp. 97, 113, 130) has 
taken up the analysis of this root made by Garrigues (Am. Jour, 
Pharm., 1854, p. 511), For panaquilon he uses the following pro- 
cess: The finely powdered root is repeatedly extracted with cold 
water until it shows no acid reaction. The several aqueous 
extracts were united and treated with animal charcoal, filtered and 
evaporated to dryness. The residue is dissolved in boiling 95 per 
cent. alcohol, filtered, and the aleohol recovered, Panaquilon remains 
as an amorphous, light yellow mass, easily soluble in alcohol and 
water, insoluble in ether, and does not contain nitrogen. Concen- 
trated sulphuric acid gives a blood-red colour, gradually turning to 
a reddish violet. Panaquilon is neither an alkaloid nor a glucoside. 
On boiling with dilute sulphuric acid a crystalline powder, panacon, 
separates, which is insoluble in water and ether, but soluble in alcohol. 
Concentrated sulphuric acid dissolves and colours it purplish red.
