232 GERMICIDES AND ANTISEFIICS. 



solution. It is doubtful, however, whether infec- 

 tious disease germs (spores) would be destroyed 

 by the most concentrated solution. " A saturated 

 solution of cloride of sodium did not destroy the 

 virus of symptomatic anthrax in forty-eight hours' 

 contact" (Arloing, Cornevin, and Thomas). 



Sodium Hyposulphite. This salt, in the writer's 

 experiments, gave no evidence whatever of germi- 

 cide power. In saturated solution it failed to kill 

 the bacteria in broken-down beef-tea, and the M. 

 of pus was not destroyed by exposure for two 

 hours to a thirty-two per cent solution. Nor was 

 the development of the last-named organism pre- 

 vented by the presence of this salt in a culture- 

 solution in the proportion of eight per cent (S). 

 Exposure for forty-eight hours to a fifty per cent 

 solution does not destroy the virus of symptomatic 

 anthrax (Arloing, Cornevin, and Thomas). Chloride 

 of lime, hard soap, chloral um, and common salt 

 are low preventives. The hyposulphite, borate, and 

 sulphate of soda are useless as such (Dougall). 



Sodium Sulphite. The results obtained corre- 

 spond with those reported in the case of sodium 

 hyposulphite (S.) 



Sodium Salicylate failed to destroy any of the test- 

 organisms used in the writer's experiments, in the 

 proportion of four per cent. But the virulence of 

 septicsemic blood was destroyed by 1.25 per cent ; 

 it must therefore have a restraining influence upon 

 the development of the septic micrococcus, and 

 doubtless upon other forms of bacteria also.
