158 Col. Bcaufnys Meteorological Observations. [Feb. 



Meteorological Observations continued. 



The quantity of vain that fell between noon, Dec. 2, and noon, 

 Jan. 1, was 2-267 inches. The quantity that fell during the 

 same period on the roof of my observatory, which is flat, covered 

 with lead, and contains 259 superficial feet, was 2-380 inches : 

 this near agreement of quantity implies that the usual conical- 

 shaped pluviometer, one foot in diameter, is sufficiently accurate.
