in water, alcohol, amylalcohol, acetic ether, very little in ether, 

 chloroform, benzol; forms salts with acids. Concentrated potash- 

 ley, also ammonia, yield crystalline precipitates in the solution of 

 the hydrochloride. Precipitates are likewise formed by chloi"ide 

 of })latinum, picric acid, potassium bi-iodide, the iodides of 

 potassio-mercury, potassio-bismuth and potassio-cadmium, bi- 

 chromate of potash, the chlorides of mercury and gold, and the 

 subchloride of palladium. With hypermanganate of potash and 

 sulphuric acid a similar but feebler violet colour is formed, as with 

 strychnin. It acts as a strong poison.] 



[Gar(leuill=:C23 H15 Oio. Crystalline resin of the Dikamali 

 resin from Gai'denia lucida. Ciystallises from the hot, alcoholic 

 solution in yellow needles, which melt at 155°. — Flueckiger.] 



[Glyeyphylliu. Glucosid of the leaves of Smilax glycyphylla. — 

 Brownish-yellow, amorphous mass, or, by slow evaporation of the 

 ethereous solution, concentrically united tufts of crystals of 

 aromatic odour and bitter-sweet taste ; dissolves better in hot than 

 in cold water, easily in alcohol and in ether ; breaks up on boiling 

 witli dilute sulphuric or hydrochloric acid into sugar and another 

 product. — Baron F. von Mueller and L. Rummel.] 



[Jurilbebill. Alkaloid of the fruits of Solanum paniculatum. — 

 Amorphous mass of bitter taste and slightly aromatic odour, little 

 soluble in water, easily in liquor of ammonia, alcohol and chloro- 

 form. The hydrochloride of J. is crystalline and yields in solution 

 precipitates with most alkaloid-reagents except chloride of plati- 

 num, picric and chi'omic acids. — F. V. Greene.] 



[Muscarine C 5 H13 NO 2 . Poisonous alkaloid of the Fly-agaric 

 (Agaricus muscarius), isolated from the extract by dilute hydro- 

 chloric acid, evaporating tlie liquid to crystals and pressing the 

 latter between blotting paper, which absorbs the deliquescent 

 Muscarin salt, while the chloride of a non-poisonous alkaloid, 

 AmamtinzrCa H13 NO remains behind.— Koppe and Schmiede- 

 berg.] 



[jVll('it=:Ci-2 H12 O12 + 4 HO. Peculiar kind of sugar, con- 

 tained in the leaves of the walnut tree (Juglans regia.) It crystal- 

 lises in klinorhombic prisms of 1"54 sp. gr., has a sweet taste, 

 dissolves easily in water, alcohol, ether and chloroform, is non- 

 rotating, does not redvice copjier salts, is unable to ferment even 

 after boiling with dilute sulphuric acid. Treated with nitric acid 

 it forms neither mucic nor oxalic acids. — Tannet and Vil- 

 liers.] 



[Ostnitllin=Ci4 H17 O2. Discovered by v. Gorup-Besanez in 

 the root of Peucedanum Ostruthium. — Odourless and almost taste- 

 less, klinorhombic crystals, fusing at 115°, resolidifying at 91°; 

 sublimable \inder decomposition, burning at the air with a bright,
