OBSERVATIONS ON THE WEATHER 
IN LONDON IN 1797. 
HE thermometer, hung out of the 
window of a rodm in the firft floor, 
‘with a north-weft expofure, gave the fol- 
lowing averages at nine in the morning : 
January 38% July 66° 
February 352 Augutt 633 
March 393 September 56,3 
April 484 OStober 485 
May 523 November 41% 
June 59 December 424 
Average of the year, 49% 
~ That of the year 1796 was 4972: {fo that 
the difference of heat in the two years con- 
fitted almoft folely in the diftribution, not 
in the fun. In 1796, the firft months were 
warmer, the middle of fummer cooler, 
and the end of the year more frofty, than. 
in1797- With refpect to heat, the year 
1797 offers little remarkable, except that 
February was colder than March, almoft 
as cold as January; and that December 
was warmer than November. The excefs 
of July above June is alfo fomewhat un- 
common.

ing it, in which it has furpafled.all the 
years for a'confiderable period. As no 
actual meafurement of rain has beentaken 
by the prefent writer, he can only give 
the loofe refult of his daily obfervations 
on the ftate of the weather. From thefe 
it appears, that the four firft months of the 
year were by no means unufually wet. 
February, on the contrary, was uncom- 
monly dry ; but fog was confiderably pre- 
_walent in it and the other, cold months.

May began with much rain; but be- 
came fine, with a high degree of heat, in 
its advance; and ftrong lightning was an 
earlier ocCurrence than ufual init. June 
was very variable: it had a fufficient 
number of fine days to engage the farmer 
im cutting down all the grafs, which the 
preceding month had brought to wnufual 
rankne{s of growth, but had alfo fuch al- 
terations of heavy rain, that hay-making 
was a very dificult and uncertain bufi- 
nefs.. July had great heats and fome tre- 
mendous thunder: it was, on the whole, 
a tolerably fair month; but was liable to 
occafional ftorms of wind and rain, which 
did much damage in beating down the 
corn, which from the length and thick- 
ne{s of its ftalk, was generally unable to © 
recover itfelf. Augult afforded very un- 
favourable weather for getting in the har- 
veft. Its nights were for the moft part 
rainy, and prevented the benefit of many 
drying days. September began pretty 
fair, but ended rairiy. One perfectly fair 
week in the beginning of OStober was the 
whole of the ufual Michaelmas fummer. 
‘The reft of the month was warm, and 
variable. Cold and wet, and wann and 
wet, were the refpeciive charaéters of No- 
vember and December, with occafionak 
tempeftuous weather, fog, and an uncom- 
mon moiiture in the atmo{phere, even 
when it did not rain. The prevalent 
winds in the whole latter part of the year 
were from the fouth and weft quarters. 
If a northerly wind one day gave an ap- 
pearance of the fetting in of winter,. a 
change on the next, raited the temperature 
of the air to autumnal warmth, and co-
