 Growth was absent in dilutions of 1-500, after 10 and 15 minutes' exposure in the case of 

 anthrax spores. With B. typhosus, growth was absent, after 5 minutes' exposure, 

 in all except in the dilution 1-1,500. With Staphylococcus pyogenes, growth was 

 present, after 15 minutes' exposure, in all tubes except dilution 1-500.

 Growth was absent in dilutions of 1-500 and 1-600, after 10 and 15 minutes' exposure in 

 the case of B. typhosus. With Staph, pyog. aureus, growth was absent after 

 5 minutes' exposure in dilution of 1-500, and absent after 15 minutes' exposure 

 in dilution of 1-600.
