air. The thermometer should therefore be excluded, not only a 
the direct, but also from the reflected heat of the sun, and it should a 
the same time be exposed toa free circulation of air; hence to cae 
a proper location is ofien very difficult. The figures in my observa- 
tions will be found lower, in many instances, than those obtained b 
other observers, in consequence of the care exercised in this respect. 
In making the morning observation, I use a self-registering thermome- 
ter, which is certain to give the minimum temperature. 
The table, which I will now present, gives the mean for. each month 
at or before sunrise, when it is the coldest, at-or afier noon, whe 
it is warmest, a eleven in the evening; th an temperature 
of the month, computed from two daily observations; also t arm- 
est and the c t mornings in each month, and the warmest and cold- 
‘est days at noon, with the range of the thermometer. Jt embraces a

warmest day in this: year was the 28h of April, when the mercury
