For the fake of comparifon, I have re- 
peated the monthly means or my lait 
rear’s Journal, under thofe of this year, 
and think it worthy of remark, how near 
the approximations of the wind agree in 
the different years ; and have to add, that 
the greateit heat here in the fhade was on 
‘the 22d of July, at one o'clock, when 
(though it was cloudy) the thermometer 
ftood at 79°;—fo early as the 5th of 
November, at 10h. 30m. in the eventing 
it was as Jow as24°. The moft remark- 
able variations that took place, were on 
the 29th of November, when at 7h. in 
(Feb. I, 
the afternoon it ftood at 15%, and at 
2th. (nine the next morning) at 34° ; 
+ 
and on the 19th of December at twelve at 
night, when it was at 9°, (the very low- 
eft that it has been this feafon), and the 
next day at twelve o’clock, it was at 38° 3 
the wind during thefe lat twelve hours 
being weft, and barometer 29.80. Ihave 
generally experienced the truth of Mr. 
Copeland’s remark, (Memoirs of Science, 
vol. i. p. 514) that in winter a rife of the 
barometer indicates approaching heat ; and 
a fall of thefame, that the cold will fhert- 
ly increafe. - ih i a 052

* It is to be remarked, that a larger depth 
of fnow having fallen in November than the 
‘tunnels\of the gauges could be fuppofed to 
receive, the {now found in each on the 28th 
of November was carefully emptied out, and 
the depth of water which the fnow then ly- 
ing on the ground would produce was afcer- 
tained by a cylindrical tin-tube, which was 
repeatedly thruft down into the fnow, ona 
{mooth place near to the feveral gauges, and 
taken up with the fnow in it and weighed ; 
and: from the known dimenfions, and weight 
of the empty tin-tube, the weight on that 
given area was afcertained ; the mean refult 
was, that the fnow then lying (about nine 
inches deep) would:produce 1.23 inches depth 
of water on the furface, and this quantity 
thas accordingly been added to, and included 
“in the feveral depths of rain in that month 
‘ia the above table. I have alfo toremark, 
‘that an infeét, or fome other matter, got by 
‘accident into the tube of the gauge on Craw- 
ley Hill, No. IL. and ftopped the water from 
defcending into the bottle, both in Septem- 
ber and October, and what was not evaporat- 
ed away ftood in the tunnel; J alfo that the 
bottle-of the gauge on Cowhill Ifland, No. 
VI. was cracked by the froft in December 
and.the water lof ; but in order to fill up 
the Table, for the fake of comparifon, the 
depths are affumed, in the above three in- 
ftances, in the fame_ratio.to the other months 
of the fame gauges, as thofe-months have to’ 
the others, in. the gauges which were ‘per- 
fe&tly obferved —I have further only tu add, 
that the general mean depth of rain for the 
year 1801, by Mr. Farey’s fix gauges, is 
24.972 inches, exceeding the depth fhewn 
by my gauge by half an inch nearly. :

SIR, 
y HAVE read with pleafure Dr. Lett- 
{om’s Oblervations on the utility of 
birds to the farmer and agriculturift, and 
Iam convinced, from all my owt obfer- 
vations, that ina general view they are 
perfeétly correét, and that birdscolle&tively 
taken do infinitely more fervice than harme
