Croom’s Hill, Greenwich, Dec 31, 1821. 
Sir,—With my last register of 1820, I mentioned that less 
rain had fallen that year than for several preceding, and that a 
want of water had been felt both by mills and canals. A similar 
observation will not be applicable to the year past, for the re- 
gister now sent shows a very great excess to the quantity of 
London and its neighbourhood, beyond many former years. The 
evaporation has been rather less than the average of the last four 
years. It may be worthy of remark, that the rainy and imost 
tempestuous weather in the two last months has been of wide 
extent, and that the great storm about Christmas, when the ba- 
rometer was so low as 28-07 (say twenty-eight inches and seven 
hundredths), was very disastrous both here and in the Mediter- 
ranean, and that earthquakes occurred in Bavaria and other 
places, As the different heights of rain gauges above the con- 
tiguous ground on which they are placed, has a wiaterial effect
