We add in Table I (6) the times or dates of the highest and 

 lowest temperatures of each year for a period of twenty 

 years, 1850-1869 inclusive; also the days of the months most 

 nearly corresponding to that of the annnal mean temperature. 



We learn from an inspection of this table that the period 

 of greatest heat ranges from June 22nd to August 31st; the 

 mean time being July 27th. That of the lowest temperature 

 extends from December 16th to February 15th; the average 

 being January 20th. The range in each case being two full 

 months. These mean times, it will be seen, fall in those 

 months whose mean temperatures show them to be the 

 extreme ones of the year.
