plete difenffion of thefe queftions were not 
lefs noble and important, than arduous 
and multifarious, from the knowledge of 
men and beoks which it effentially involv- 
ed in it ; and the time, I truft, is approach- 
ing, when the inyeftigation of fuch topics 
will be thought worthy of exercifing the 
fineft talents of our fpecies ; for what tc. 
pics, in truth, can compare with thefe in 
dignity and intereft ?

To the Editor of the Monthly Magazine. 
SIR, 
INCE I have removed to Leighton, 
have been careful to keep a meteoro- 
logical journal ; and as I do not know of 
any one being kepr near this placé, it may 
not be uninterefting to fome of your phi- 
| fopbical readers ot the Monthly Maga- 
zine to fee the half-yearly averages and 
aggregates of the feveral meafures. The 
journal for the half-year ending the 3oth 
of June, 1800, ‘is below :

Tt being the fir time of communicating gical meafures. Thefe difficulties are 
to you on this fubjeét, it will be neceflary 
to give an explanation of the sournal.— 
And of the five firt columns at prefent I 
fhall only defcribe the fituation of the in- 
firuments. The barometer hangs about 
$15 feet above the level of the fea by efti- 
mation, taking the level from the Grand- 
Junétion Canal, which runs by this place, 
udmitting the levels to be accurate in the 
furvey of the canal. On the fame rule of 
eltimation the rain- guage and evaporation- 
gucge are about 336 feet above the fame 
Jevel, and are 30 feet above the furface of 
the ground. ‘They are placed too far 
from any thing that is above their level 
to be affected by it 3; and I am fatisfied 
that it can neither rain into the evapora- 
tion guage nor evapcrate out of the rain- 
guage. 
Next refpecting the wind. Mott people 
are acquaintea with the difficulties there 
4re in making a comparifon of the direc: 
tions of the wind at different places, in the 
average or total, like all other meteorolo- 
avoided by the mcthod I ufe, which 
is extremely fimple, and, I believe; effec- 
tual, 
Suppofe the 
circle or horizon 
divided into fix- 
teen equal parts, 
and numbering 
them both ways 1 
on the outfide, 
from the eatt 
and welt to the 4 
north and fouth, 
the fame on the 
infide, from the 
north and fouth 4S 3 
to the eaft and weft, and cal! them the de- 
grees of approximation to the cardinal 
points: noting down in its proper column 
the degree on the outfide, and the fame on 
the iafide the circle. An example, per- 
haps, may explainit nearer. Suppofe the 
common notations of the wind for a week 
ftood thus :—
