From the data obtained we can form the following table of ger- 
minations, the temperature noted being for the twelve hours preced- 
ing each count, and the numbers referring to the number of kernels 
removed at each examination. Curiously enough 100 per cent ger- 
minated in the total for each sort:

‘The Dent corns germinated at a temperature whose average was 
47°, and extreme 47.6°; the Flints, Pops and Softs at a temperature 
whose average was 47.1°, and extreme 47.8 ; the Sweets at a tem- 
perature whose average was 47.0° and extreme 48.5°. 
Under similar circumstances the Dents commenced germination 
the 168th hour of the trial; the Flints the 216th hour; the Pops 
and Softs the 228th hour, and the Sweets the 228th hour. 
The temperatures maintained for the 408 hours average 47.9°,the 
extremes being 44.7° and 50.7°. 
The number of hourly observations recorded was 276. Interpo- 
lating the figures for the unobserved hours, we can form the follow- 
ing table, for the hours after the first twenty-four, which in all 
probability had but little part in the germination, but only in the 
soaking of the seed : 
Number of hours at observed and interpolated temperature to 
first germination, after the first twenty-four hours:
