204 BACTERIAL POISONS. 



allii, a germ obtained from putrid onions. The base 

 (hydrochloride ?) forms colorless, prismatic, microscopic, 

 very deliquescent needles, which are soluble in warm water, 

 alcohol, ether, and chloroform. It gives off a hawthorn-like 

 odor, especially when warmed. With phosphomolybdic acid 

 it yields a white; with iodine in potassium iodide and with 

 tannic acid a chestnut-colored precipitate. NESSLER'S solu- 

 tion produces a yellow chestnut-colored precipitate. Picric 

 acid throws down a yellow slightly soluble deposit. The 

 platinochloride, (C 10 H 17 N.HCl) 2 PtCl 4 , is yellow, crystalline, 

 and difficultly soluble in cold water and in alcohol ; soluble 

 in warm water. Gold chloride produces a thick yellow 

 precipitate soluble in water. Dilute sulphuric acid pro- 

 duces a violet-red color. The base is apparently a hydro- 

 coridine. 



A BASE, C^H^N, was obtained by DELEZINIER (1889) 

 and is said to be the alkaloid, isolated in 1879 by BROUAR- 

 DEL, which in its chemical and physiological properties was 

 described as similar to veratrine. It forms an almost color- 

 less oily fluid, which possesses a hawthorn-like odor. It 

 is very readily oxidizable and yields the veratrine-like re- 

 actions only in the presence of air. It is soluble in alcohol, 

 ether, toluene, and benzene; and forms well-defined salts 

 which are very deliquescent. It appears to be an amine, 

 and in its composition differs from eevadine by 9H 2 O. 

 Nothing is stated in regard to its source or method of 

 preparation. The analytical results given C = 89.41, 

 H = 7.3, N = 3.03 correspond more to the formula 



ETHYI,IDENEDIAMINE(?), C 2 H 8 N 2 . This base was con- 

 sidered at first by BRIEGER to be identical with ethylene- 

 diamine, but subsequent comparison showed this to be an 

 error. Thus, the former is poisonous and does not form 

 a gold salt, while the latter is not poisonous and does form 

 a rather difficultly soluble gold salt. Again, ethylcne- 

 diamine forms a platinochloride which is almost insoluble 

 in hot water, whereas the platinum double salt of the pto-
