216 GERMICIDES AND ANTISEPTICS. 



cent did not destroy the virulence of septic blood, 

 which was injected into a rabbit with a fatal result. 

 Twice this amount, however, proved effectual (S). 



Aluminium Acetate. The development of bac- 

 teria in pease-infusion is prevented by 1 : 5,250 

 (Kiihn). The development of bacteria in un- 

 boiled beef-infusion was prevented by 1: 6,310; 

 and the bacteria of broken-down beef-tea were 

 destroyed by 1: 478, while 1: 584 failed (de la 

 Croix). 



Aluminium Chloride. " Group III. Salts of 

 the Alkaline Earths. Here chloride of aluminium 

 is highest. . . . Were it not for the extremely 

 high preventive point (1: 2,000) of this salt in the 

 hay column, this group would occupy a compara- 

 tively subordinate position" (Dougall). 



Ammonia does not destroy the virus of sympto- 

 matic anthrax (Arloing, Cornevin, and Thomas) ; 

 or the spores of the anthrax bacillus (Koch). 



Aromatic Products of Decomposition. Bauman first 

 showed that phenol is developed in albuminous 

 fluids during the process of putrefaction ; and Sal- 

 kowski found, in 1875, that old putrid fluids have 

 antiseptic properties. Wernich has studied this 

 subject, and finds that the aromatic products of 

 decomposition, skatol, phenyl, propionic acid, in- 

 dol, kresol, phenyl acetic acid, and phenol, arrest 

 putrefaction, when present in organic infusions in 

 small quantities, in the order named. 



Arscnimis Acid. One per cent destroys spores 

 of bacilli in ten days (Koch).
