Mean temperature for the year 54.56 ; being two degrees greater 

 than that of the year 1832 — and is the tegular mean for this climate. 



The fluctuations of the Barometer, have been small this year ; the 

 greatest range being only .90 of an inch. The lowest depression was

Total amount of rain and melted snow, 40.37 inches, being eight 



inches less than that of the year 1832. Fair days, 222 — cloudy 



days, 143, varying only six from that of last year.

 probably owing to the early fall of snow in the Arctic and Rocky
