Mean, |54.56 t 222/143/40|37 
Mean temperature for the year 54.56; being two degrees greater 
than that of the year 1832—and is the regular mean for this climate. 
The fluctuations of the Barometer, have been small this year; the 
greatest range being only .90 of aninch. ‘The lowest depression was 
on the 17th Dec., with the wind from the E. and snowing rapidly. 
The greatest elevation, was on the 3lst of Oct., wind at the N. 
The mean height for the year is 29.46. My Barometer is new, 
and I believe accurate. : 
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 years 
The mean temperature for the winter months is 26.20

The winter being milder by two degrees than that of 1832; and the 
summer six degrees warmer. October was unusually cold, the ther- 
mometer being no less than nine degrees lower than that of April, 
when they are commonly of near the same temperature. It was 
probably owing to the early fall of snow in the Arctic and Rocky
