with the chlorides of hydrogen and gold, and it is 

 precipitated by phosphomolybdic, picric, and phos- 

 photungstic acids. 



Tetanine (C 13 H 22 lSr 2 4 ). Brieger succeeded in 

 isolating this ptomaine from pure cultivations of 

 the tetanus bacillus. This base produces tetanic 

 convulsions and death. Its hydrochloride is very 

 deliquescent. In 1888 Brieger 1 obtained another 

 oxygenous ptomaine from pure cultivations of the 

 tetanus bacillus. It is represented by the formula 

 C 6 H 13 N0 2 , and is non-poisonous. 



Diphtherine (C U H 17 N 2 6 ). This base was ex- 

 tracted by the author 2 from the urine of patients 

 suffering from diphtheria, as well as from pure cul- 

 tivations of Bacillus diphtheria (bacillus No. 2 of 

 Klebs and Loffler). It is a white crystalline base, 

 and it forms double salts with the chlorides of 

 hydrogen and gold. It is precipitated by tannic, 

 picric, and phosphomolybdic acids. 



Unknown Base (C 5 H n NO). This ptomaine was 

 extracted by E. and H. Salkowski from putrid fibrin. 

 It forms double salts with the chlorides of hydrogen 

 and platinum. Gabriel and Aschan 3 have recently 

 proved that this ptomaine is &-amidovaleric acid. 



Unknown Base (C 14 H 20 N" 2 4 ). This base, which 

 is believed to be an amido-acid, was extracted 

 by Guareschi 4 from putrid fibrin. It occurs as
