EXPERIMENTS MADE IN 1906 37 



different temperatures from 115 to 130 C.; 1 and 

 after citing what was known concerning the 

 thermal death-point of the organisms found, as 

 previously determined and admitted by bacteri- 

 ologists, the experimental results were embodied 

 in the following statement : " It comes to this, 

 then, that all the organisms found in my experi- 

 ments, with the exception of Bacilli, are such as 

 would be killed at 100 C.; that these latter, so 

 far as they could by any possibility be found 

 within my tubes, should have been killed in one 

 or two minutes at 115 C.; yet Bacilli, as well 

 as Bacteria, Vibriones, Micrococci, Streptococci, 

 Torulge, and other Fungus-germs, dying under 

 100 C., have been taken in large numbers from 

 tubes that had been heated to 115-130 C. for 

 ten to twenty minutes." 



1 The number of experiments described with illustrative 

 photographs will be found to be more numerous in my work, 

 subsequently published, entitled The Evolution of Life, 1907.
