the ground for last year was 38-507in., and in the one 34ft. 
from the ground it was 32-921in. The difference between 
the fall in the two gauges is 5 '5 8 Gin. or about 18 per cent 
less rain fell in the higher gauge than in the lower one. In 
the same table I give the average fall in the same gauges 
for eight years, and by comparing the results it will be 
found that the average difference between the fall in the 
two gauges is about 17 \ per cent, very nearly the difference 
I showed last year on a seven years’ average.

The following table gives the ratios of the excesses of 
rainfall 3ft. from the ground over the amount measured at 
34ft. from the ground. It is astonishing how these ratios 
vary their places in each single year, and yet how they 
maintain their positions in and after a six years’ average. 
There was absolutely no comparison between the ratios of 
' the single years of 1873 and 1874 and the ratios of the six 
and seven years’ averages, which were almost identical. 
So also of these ratios of last year, there is not the slightest 
comparison between them and the eight years’ average, and 
practically there is no difference between the six, seven, and 
eight years’ averages. Now, according to the seven and
