192 BACTERIAL POISONS. 



obtained from poisonous sausage on intestines and on meat 

 bouillon (EHRENBERG, 1887). 



It is an inflammable liquid which boils at 57.5, possesses 

 strong basic properties, and is soluble in water. 



The HYDROCHLORIDE, (C 2 H 5 ) 2 NH.HC1, crystallizes in 

 needles (BOCKLISCH) ; in long needles and prisms from 

 absolute alcohol ; in plates from ether-alcohol. These are 

 not deliquescent and are easily soluble in water and in 

 chloroform ; rather difficultly in absolute alcohol. Heated 

 with sodium hydrate it gives off alkaline vapors. From an 

 alcoholic solution it is precipitated by addition of alcoholic 

 mercuric chloride. The mercury double salt is difficultly 

 soluble in hot water, from which it recrystallizes on cooling. 



The PLATINOCHLORIDE, [(C 2 H5) 2 .NH.HCl] 2 Pt01 4 , crys- 

 tallizes in orange-yellow monoclinic crystals, which are 

 easily soluble in water. 



The AUROCHLORIDE, (C 2 H 5 ) 2 .NH.HCl.AuCl 3 (Au = 



47.71 per cent.), forms trimetric crystals (ToPSOE), which 



are difficultly soluble (BOCKLISCH). It melts at about 165. 



With picric acid it forms an easily soluble picrate (LEA). 



TRIETHYLAMINE, C 6 H 16 N = (C 2 H 6 ) 3 N, was obtained 

 by BRIEGER (1885) from haddock which were exposed for 

 five days in an open vessel during summer. He obtained 

 it by distilling with potash, after removal of platinum by 

 hydrogen sulphide, the mother liquor from which neuridine, 

 the base C 2 H 8 N 2 , muscarine, and gadinine had successively 

 crystallized (see Gadinine). It has also been found by 

 BOCKLISCH (1886) in putrid pike, and by EHRENBERG 

 (1887). The latter obtained it from cultures of a bacillus, 

 found in poisonous sausage, and grown on meat bouillon. 



The free base is oily in character and possesses an am- 

 moniacal odor. It is but slightly soluble in water, and 

 boils at 89-89.5. 



The PLATINOCHLORIDE, [(C 2 H a ) s KHClJ a PtCl 4 (Pt = 

 31.84 per cent.), crystallizes in needles which are readily 

 soluble in water. 



With mercuric chloride the aqueous solution gives no 

 precipitate.
