the more or less delayed putrefaction which takes 
place in inoculated organic infusions raised to the 
temperature of 140° F., and to other degrees of heat 
above this point, is due to the influence of the not- 
living ingredient (4) of the inoculating compound. 
These reasons are the following :— 
1. Because the turbidity which has occurred in 
inoculated organic infusions that have been subjected 
to a temperature of 140° F. has always manifested
