It wil be observed from this state- 
ment, that the general average of heat 
for the whole year differs but little from 
that of the last. It is about one degree 
ecider, though we had in the month of 
July hotter weather than was probably 
ever known.in this country. The tem- 
perature for January, March, April, 
June, July, August, and October, has 
been lower this year than the last; in 
the other months it has been higher. 
The year commenced with stormy wea- 
ther, which did much damage on the 
coast, and in some of the interior parts 
of the country. Of some nights towards 
the latter end of the year a similar re- 
mark may be made; and in many parts 
of the kingdom, several days in the month

Afeteorological Observations. 
[ Feb. te 
of July were remarkable for storms of 
hail, accompanied with thunder and 
hghbtning. One, on the 15th of that 
mouth, has been described with much 
interest in the last volume of the Month- 
ly Magazine, (See vol, xxvi. p. 302— 
8.) by an eye-witness; to which 
the reader may be referred, as well 
for the facts contained in it, as for 
the many judicious phiiosophical obser- 
vations incorporated with it. I have 
in my meteorological reports, attached 
to each number, recorded the principal 
facts relating to this subject, which will 
render it unnecessary to repeat what will 
be found in their respective places. I 
shall therefore only give a sort of sum- 
mary for the whole year. 
The average of heat, as “may be seen 
above, is 50.619, and the average height 
of the barometer 1s 29.724, which is 
something less than what it was the pre- 
ceding year: and the quantity of ram 
fallen is 30.55 inches in height for the 
whole year. The greatest cold in the 
year was on January 22, and the great- 
est heat on July 14. 
Of the 366 days, 162 may be deno- 
minated brilliant, that is, days in which 
the sun was scarcely covered for any 
Jength of time with a cloud—39 were 
fair—29 cloudy, in. which the sun was 
not seen—on 119 there was rain-—and 
on 18 there was either snow or hail. 
The wind has blown 38 days from the 
north—19 from the south—52 from thie 
west-——54 from the east. In the north 
east it has been 44 days—south-east 37 
——north-west 65—and south-west 57. 
It may not be uninteresting to bring 
into one point of view the average state 
of the atmasphere for the last seven years. 
The reader will recellect that the obser- 
vations were made at Camden-Town, a 
village about two miles north-west of St. 
Paul’s cathedral.

The only remark that I shall make is, that the quantity of rain in the whole 
year is not by any means proportional to the density of the atmosphere.
