month was thought sufficient during these three years. he d 
process was to apply a correction daily to the mean of the nxim 
theca 
and minimum temperatures, dependent upon the time of rear. 
deduce from these a second approximation to the true men 
temperature, and which corrections are as follows :—

By the application of these numbers a second mean daily tempratn

The next process was to compare the daily results deduced Dm t] 
three observations with that found from the maximum and niimu
