584 OBSERVATIONS ON THE BAROMETER, 
Mr. Henry Hough Watson of Bolton-le-Moors 
has forwarded to me the particulars of his obser- 
vations on the Barometer and Thermometer, and 
also the quantity of rain, &c., for 10 years, which - 
are arranged in the following tables. 
The town of Bolton is about 320 feet above the 
sea, and situated 11 miles north-west of Manches- 
ter, below a range of hills commencing about 
south-east, and passing to a little west of north ; 
the summits of these hills are from 3 to 6 miles 
from the town, and rise to an elevation of from 
400 to 1000 feet above it. The country towards 
the south and west is very flat to the distance of 
30 or 40 miles, and therefore the immediate 
neighbourhood of the town is exposed to the cur- 
rents of air from that direction.
