Although the month of October again exhibits the Temperature 

 most closely approximating to the Mean of the year, the approxima- 

 tion is not quite so close as on the former instances. The Minimum 

 of October differs only — 0.83° from the yearly Minimum, but the 

 mean differs, — 4.06°, and the Maximum — 2.75°. 



The highest indication of the Thermometer during 1839 was 94° 

 on the 29th of June, the lowest 40° on the 24th of January, thus 

 giving an extreme range throughout the year of 54°, which is 8° 

 greater than that of 1838. The Mean range is 39.17°. being 4.26° 

 greater than in the preceding year. The Mean of the two Annual 

 extremes is 68.79°, being thus only 0.40° different from the Mean 

 Temperature of the year.
