502 - Meteorology. — 
are amongst the driest; the only months dis- 
tinguished for heavy rain, are September, 
October, and November; whilst Apri} and 
May yield each more than the monthly 
average. 
I have collected the Royal Society’ $ ace 
count of rain at London for 28 years, ending 
in 1806, and find the averages to stand as un- 
der; also those of Luke Howard, Esq. for a 
subsequent period of 12 years, ending with 
1818, made in the vicinity of London.— These 
united are as per table. 
The fall of rain at Kendal for 5 ei 
(1788—1792) was published in my Meteoro~ 
logy ; since that time the account has been 
continued by my brother for 18 years, with 
which he has favoured me; I have obtained 
also 2. years further from good authority, 
making in all, 25 years’ ram. The monthly 
averages I have deduced as per table. 
I deduced the average rain at Paris, from 
observations published in the Journal de 
Physique for the last 15 years, as per table. 
The average rain at Glasgow for 17 years 
(1801—1818) was deduced from a paper in’ 
the Annals’ of Philosophy, Wol. 12, page 
377. |
