272 BACTERIAL POISONS. 



hydrochloride formed small, readily deliquescent needles, 

 and did not produce a precipitate in alcoholic platinum 

 chloride. Injected into guinea-pigs and rabbits it induced 

 an exalted peristaltic action of the intestines, which lasted 

 several days, and produced in the animals, on account of 

 the continuous evacuations, a condition of great weakness. 

 No disturbance in the functions of the other organs was 

 observed. 



A BASK was isolated from decomposing haddock which 

 were exposed for five days during summer in an open iron 

 vessel. BIUEGEH (I., 42) found in the aqueous mercuric 

 chloride precipitate (see page 258) a base the hydrochloride 

 of which crystalli/cd in well-formed, small needles. The 

 platinochloride likewise crystallized in beautiful needles, 

 and gave, on analysis, 36.03 i>er cent, of Ft; 7.81 per cent, 

 of N. 



A substance of muscarine-like action was obtained by 

 BUIEGER (I., 59) from putrefying gelatin, ten days at 

 35, though in insufficient quantity to permit a determina- 

 tion of its character. The residue containing this substance 

 gave, on distillation with alkali, only ammonia. 



A BASE was obtained by BOCKLISCH (III., 52, 53) from 

 herring which had undergone putrefaction for twelve days. 

 It was found in the distillate, together with trimethylamine 

 and dimethylamine, obtained by distilling the mercuric 

 chloride filtrate, after the removal of the mercury, with 

 sodium hydrate. The platinochloride was easily soluble, 

 and crystallized in large thin plates. On analysis it gave : 

 Pt = 28.57, C = 22.34, H = 4.66. The hydrochloride is 

 easily soluble in water, and in absolute alcohol, and l>e- 

 sides with platinum gives only with phosphomolybdic acid 

 a yellow precipitate which is soluble in excess, and with 

 ammonia gives an immediate blue color. It immediately 

 reduces a mixture of ferric chloride and potassium ferri- 

 cyanide with formation of Berlin blue ; and similarly
