The lowest temperature recorded was on December 22 nd, when 

 the min. thermometer registered 4*^3 or nearly 28" below freezing 

 point. The highest temperature, 79"5, was recorded on August 6th. 

 The atmosphere was dryest during May, when the relative humidity 

 was only 67 "4. The air was most moist during February and 

 September, yet this latter month was the month of least rainfall. 

 Probably this coincidence had some relation to the extensive preva- 

 lence of typhoid which commenced in that month. The rainfall for 

 the year was a little below the average for the past ten years, Mr. 

 Impey's register at Bloomfield Hall giving 22*5 in. as the average for 

 that period. 



A Dry February. — Mr. \V. II. Penrose, J. P., of the Rookery, Dedham, writes as 

 follows : " A month without a drop of rain is beyond my former experience. Such 

 has been the month of Februar\-, 1891, the moisture registered being the result of 

 the dense fogs so generally experienced. .01 inch (fog) was registered on Feb. 4, 

 6, 20, 22, 23, 24, 25, and 26 ; and .01 inch on Feb. i (white frost). The total for 

 the month was .09 inches."
