^771* f I time, I have made out from my 
minutes, a detail of the remarkable cold which pre- 
vailed here in the month of January, 1768; the 
intenfity of which being fo extraordinary for this 
climate, an account of it may perhaps be thought 
worthy of a place in the Philofophical Tranfac- 
tions. 
Whilft in bed, on funday morning, January 3, 
1768, about 8 o’clock, it felt fomehow unufually 
cold. A little while after, on reaching out for a 
decanter which I had placed near me the preceding 
night.
