SOME EXPERIMENTS WITH DISINFECTANTS 



21 



The cultures used had been recently isolated, the Staphylococcus 

 being isolated from an acute abscess, the B. typhosus from a recently 

 fatal case of typhoid fever, and the anthrax from a recent case, and in 

 an actively sporing condition. The formaline was tested just before 

 commencing the experiment, and was found to contain 32 per cent, 

 of formaldehyde gas, so that the different dilutions given must be 

 calculated upon that basis and not the ordinary one of 40 per cent. 

 The various dilutions of the disinfectants employed were such as are in 

 common use for disinfectant purposes. 



The following results were obtained : — 



FORMALINE (Strength 32%).
