- [ 77i ] 
The Barometer made ufe of for thefe obferva- 
tions has a tube ^ of an inch diameter, and 
holds 2lb of quick-iilver. 
The height of the quickfilver I generally take 
about 7 o’clock in the morning, 2 in the after- 
noon, and 9 at night ; and the different changes 
in the weather as they happened in the day. 
I have divided the fcale of my barometer in inches, 
from 28 to 31, and each into 20 parts, fo that 
when you find in this journal 29 it is 29 
inches parts of an inch.
