the sea-level being 198 feet.« The mean yearly fall for those 
eleven years is 29.75 inches, 
If now, for the sake of better comparison between the several 
places above mentioned, including the Literary Institution,—we 
take the mean yearly rain-fall at each of them for the eight years, 
commencing with 1866 and ending with 1873,—the only period 
for which they can be all compared together,—the result is as 
follows :—

I have given in each case the height above the sea as it adds 
to the value of the comparison ; and it will be seen that in the 
case of these particular localities there appears no marked rela- 
tionship between the height and the rain-fall. The difference in 
height between the Institution and the Reservoirs is more than 
150 feet, with only a difference of .09 inches in the rain-fall. 
The rain-fall at Upper Swainswick was measured by the late 
Mr. Frederick Lockey for a period of thirty years, 1834—1863. 
The gauge was at the height of about 32 feet above the ground 
and at an estimated height of 350 feet above the Avon. The average 
yearly fall as determined by his registers is 25.86 inches. The 
wettest years in the series are 1839, when the fall was 33.08 inc.,— 
1848, with a fall of 34.38 inc., and 1852, when the fall reached 
to 42.64 inc. In this last year the fall in the month of November 
was 8.32 inc., being the greatest quantity of rain in any one month 
_ during the thirty years. The driest years in the series are 1840, 
R __ * The yearly rain-fall measurements at the above three places—Weston, the 
Batheaston Reservoirs, and the Paragon, have been taken from Symons’ 
“British Rain-fall ; those relating to the Paragon in connection with Mr. 
Barter’s “ Sanitary conditions of Bath,”’ p. 5.
