The highest observed was at 9 in the morning of the 9th ; 
but it is probable it had been higher during an earlier part of 
that day. 
The lowest temperature during the night between the 8th 
and 9th, was 18|°. In several days after, the thermometer 
did not sink below 27°. On the ni^ht between the 16th and 
17th, it sunk to 13J°, and during the next night, or rather on 
the morning of the 18th, it was at zero, which was the lowest 
at Kinfauns. 
The following is the state of the Thermometer observed 
by Mr Gordon on the 18th January 1820:

The barometer during the 18th sunk gradually from 29.425 
at 10 morning, to 29-245 at 10 evening. The elevation of 
this place is 185 feet, so that the barometer at the level of the 
sea must have been as high as 31.045, on the 9th.
