On comparing this table with that in the Annals, vii. 67, it will 
be seen that 1815 was considerably warmer than 1814. The tem- 
perature of London, given in the third column, from the registers 
of the Royal Society, is certainly too high, as the Society has not 
a Six’s thermometer, and no observations are made during the 
night. [believe the mean temperature of London to be rather 
under 50°; but certainly very little under it. The mineral spring 
at Tunbridge Wells is constantly of the temperature 50°, which 
undoubtedly represents the mean temperature of the year in that 
place. Now London, being further north, is probably a little 
colder. From 1814 and 1815 it would appear that the mean tem- 
erature of Plymouth is about 1°5° higher than that of London. 
This difference falls chiefly on the autumn and winter months, and 
is no doubt partly owing to the difference of latitude, and partly to 
the neighbourhood of the sea, The mean temperature at Perth is 
45°4°. 
The quantity of rain which fell in 1815 in different parts of Great 
Britain is as follows :—

The summer and autumn of 1815 were remarkably dry, and the 
weather delightful, yet the crop was excellent,

I have so little room to spare, that I can merely name some of the 
most striking improvements in the arts which have been proposed or
