ble to crystallize it from alcohoL The alcoholic solution has 
an acid reaction. It affords with — 
Chloride of Platinum, a yellow crystalline precipitate. 
Perchloride of Mercury, a white percipitate turning gray. 
Ammonia, a brown flocculent precipitate. 
Potash produces a turbidness, and when added in large 
quantity separates the resin. 
Carbonate of Soda produces a yellowish-brown pulve- 
rulent precipitate, as does carbonate of ammonia. 
Nitrate of Silver causes a considerable reddish-brown 
precipitate. 
Sulphuric Jicid precipitates a brown powder, as does 
also hydrochloric acid, only the colour is somewhat more 
yellow, 
A slight excess of ammonia added to a solution of the 
cenanthic resin in acetic acid produces a brown pulverulent 
precipitate, which possesses the chemical properties of the 
substance above described, but is not resinous. To this 
substance the author gives the name of cenanthine, and sup- 
poses it to be combined in the oenanthic resin with an acid ; 
since on the distillation of an alcoholic extract of the resin, 
resin constantly separates in the retort during the operation, 
whilst above the level of the liquid a whitish ring is depo- 
sited, which is volatilized and passes into the distillate. This 
forms a white, milky, faintly-acid liquid, with an odour 
similar to the cenanthic resin, but considerably milder and 
more agreeable. The author supposes it to contain a vola- 
tile acid, but was prevented, from want of material, from 
extending his inquiries furiher on the subject. It has a pow- 
erful effect upon the animal system ; half a grain adminis- 
tered to a full-grown person produces a long-continued irri- 
tation in the palate, followed by a hoarseness of two to 
three hours, duration; one grain sufficed to produce a slight 
vomiting. It may therefore prove interesting in a therapeu- 
tical point of view. — Chem. Gaz. from Journ.fur Prakt.
