extraordinary Degree of Cold at Glafgow. 45 5. 
All the afternoon the cold was very intenfe, and at 
feven o’clock at night the thermometer at the high 
North window pointed to gr. o. At eight Dr. irvine 
and 1 repaired to the Obfervatory, and made choice of 
a ftation at a fufficient diftance from the houfe, and to 
the windward, as a light air was felt coming from the 
Eaft. Here we laid down two thermometers on the 
fnow with their balls half immerfed, and hung up 
other two freely expofed to the air at two feet and a 
half from the furface. 
In the following obfervations the interruption of the 
feries from af to 6j o’clock was owing to an accident 
having befallen one of the thermometers whilft the 
other was employed in the trials, of which an account 
is-fubjoined..
