Meteorological Observations. 159 
mencing January 1831, is 29°564 inches. With the exception of 
yesterday, the lowest height of the barometer during the time which 
has elapsed since I commenced keeping a register, was 28°04 inches : 
it occurred at 6 p.m. on the 13th of November 1840. 
The weather in the early part of yesterday, and tili evening, was 
similar to what it had been for several days previously ; a little snow, 
hail and rain falling at intervals. The wind was rather south of 
west, but not strong, till about 7 p.m., when it began to blow 
strongly, and during the night and till daybreak this morning was 
very boisterous ; it then began to abate, and by 9 a.m. was not un- 
usually strong. 
The temperature here yesterday ranged from 35° to 36°; today 
it has ranged from. 34° to 30°: at half-past 10 on the night of the 
12th instant it was 27°, and the height of the barometer at that 
time was 28°70 inches. Today the height of the barometer has 
been at § a.m. 28°58 inches; at half-past 12 p.m. 28-54 inches, and 
at half-past 10 at night 28°57 inches; the weather similar to that of 
the several previous days. 
It will be found by reference to the observations of Mr. Luke 
Howard, page 69, vol. iii. of his work, entitled «‘ The Climate of 
London,” that a depression of the barometer, similar to that of yes- 
terday, occurred in December 1821. 
I remain, Gentlemen, yours most respectfully, 
Bolton-le- Moors, Jan. 14, 1843. Henry Hoven Watson.
