From the above record it is an even probability that the tem¬ 
perature will exceed or fall short of 94.6° for its maximum and 
-23° for its minimum. The average temperature is 45.7°? with a 
probable error of 0.2° ; or it is an even probability from present in¬ 
formation that after a much longer series of observations, the 
average will be found to be between 45.5° and 45.9.° 
There is also given in Table I the monthly averages of tempera¬ 
ture as found throughout the twenty years; in Table II, the table 
of extremes for each month; in Table III, the average daily range 
for each month.
