Temperatures: — The total number of records for January is 

 485, as follows: 5 for 1899; 93 for 1900, 1901, 1902, 1903 and 

 1914 each ; 12 for 1905 ; 3 for 1906, and 1 for 1907. 



The lowest temperature recorded for this month was — 12° on 

 the 27th and again on the 28th, in 1902. The highest was 65° 

 on January 20, 1906. The extremes for each year were as follows: 



1900, -8° January 31, and 42.5° January 18; range 50.5°. 



1901, -1.3° January 1, and 45° January 21; range 46.3°. 



1902, -12° January 27 and 28, and 38° January 2; range 50°. 



1903, -4° January 12, and 50° January 29; range 54°. 

 1914, 4° January 12, and 56° January 29; range 52°. 



Records of temperatures at or below freezing were made as 

 follows : In 1899, at 6 a. m. on the 8th, 29th, 30th and 31st, the 

 only dates on which temperatures were recorded ; in 1900, at 6 

 a. m. on the 1st to 4th, both inclusive; 8th, 9th, 11th, 12th, 13th, 

 16th, 17th, 21st, 22d, 23d, and 25th to 31st, both inclusive, and
