* Left the plates in the oven to cool. 
Two inoculated plates set outside the window during freezing weather for 12 hours were then maintained at room temperatures for 10 
days without showing any signs of germination. As the table shows, in nearly every case where the plates had been heated for 15—20 minutes 
ed 
a large percentage of the spores germinat 
At the end of one hour the temperature of the oven was still 55°
