HE winter feemed to fet in about the middle of 
November; from that time to the end of the 
month we had fome fnow and cold weather; but the 
thermometer never was lower than 1 6° or 1 8° below the 
freezing point. 
About the 24th and 25 th of December people crofied 
the river three miles below Montreal. 
The letters a and b after the figures denote the mer- 
cury to be above or below o. The thermometer from 
which thefe obfervations were taken, was of Fahren- 
heit’s conftrudlion ; it was fufpended to a poll, perfedtly 
in the fhade, and no building nearer to it to reflect the 
heat than five or fix feet.
