 The greatest quantity, 52.6 inches; (viz. in 1821) and the

I find by my notes, that the quantity of snow which fell,

The water which fell in the form of snow, is included in 

 the foregoing table of rain. 



The number of days of falling weather, so called, (inclu-

 following table: by which it appears that the highest num- 

 ber is 103, (in 1818) and the lowest, in any entire year, 84, 

 (in 1822.) The average number of days, on which there
