Mean temperature for the year 1848 . . • . 47*5° 



" 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.,

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.
