Falls of over five indies occurred :—June 1848 (7 35); 1872 
(5‘45) ; July 1880 (5 21) ; 1888 (6-15); August 1857 (6-59); 
1865 (5-28); 1878 {5-07) ; September 1870 (6-30); October 
1869 (6‘10); December 1868 (6 07); 1876 (5'95). 
Thus, only on 11 occasions, and in six months, has the month’s 
fall exceeded five inches. 
It is curious that, during the wettest year, 1872, tlie wettest 
month, November, gave only 4’28 inches 
Relation of 
Rainfall and 
barometer. 
It may be in part accidental, but is certainly significant, that 
the wettest year, 1872, had the lowest mean pressure, and the 
driest year, 1887, almost the highest. Taking the sixteen 
wettest years and the sixteen* driest; also the fifteen of highest 
pressure, and the fourteen of lowest; and the seventeen hottest 
and sixteen coldest, we get the following results -

In all these sets, although none of the individual results are 
very marked, we find much rain, low pressure and warmth 
connected, and vice-versa. This merely confirms a well-known 
association. It is curious to note how close the average of the 
two extreme thirds approaches the mean in all these eases, even 
when, as in Dainfalls, they are respectively so divergent.

out 18 “ average ” years. liCss or more are taken on account of several years of 
equal value.
