The temperature of 1848 has been almost exactly a mean 
of 18 years. January was, as usual, the coldest month, and 
July the hottest. The former month was three degrees below 
a mean, the latter an exact mean. August was also nearly 
four degrees below a mean. The rain of 1848 has exceeded the 
mean by 12 inches. The quantity fallen is 36*02 inches, being 
more than that of any year since 1832, and probably more than 
that of any recorded year. The rain of February, March, June, 
and September, taken collectively, was 240 per cent, above the 
annual mean of those months. The rain of June (7*35 inches) 
was more than that of the same month in any one of the last 
eighteen years: on the contrary, that of November was only 
1*13 inches, being less than had fallen in that month in any 
one year of the above named series. The 17th of October was 
marked by a heavy fall of snow. The same phenomenon oc¬ 
curred on the same day of October, 1843. A magnificent display 
of auroral light occurred on the 17th of November. This was 
remarkable for the rapidity of the coruscations and the mag¬ 
nificence and depth of colour of the red arch, which, at half¬ 
past 9, spanned the heavens from N. E. to S. W.” 
The following accounts of the amount of rain fallen in the 
year have been received : viz., 
Doncaster . 33-85 inches. 
Kirby Moorside. 36-56 ,, 
Ackworth . 32-08 „ 
Settle . 57-49 „ 
At the Monthly Meetings of the Society, which have been 
held as usual, several valuable papers have been read. A selec¬ 
tion from those relating to the Natural History and Antiquities 
of Yorkshire has been printed, and will be found in the first 
part of the Proceedings of the Society, which the Council have 
the pleasure of laying upon the table.
