The rainfall for 1870 was remarkable for its very irregular 
distribution over the year. The total amount collected was 
5'988in. below the average of the last seventy-seven years : 
it fell upon 155 days, or upon 55 days less than in 1869. 
During the first, second, and third quarters of 1870, the 
rainfall was below the average of the corresponding periods 
of the last seventy-seven years : whilst the fourth quarter 
was in excess, but by no means making up for the previous 
deficiency. 
January, March, April, and October, had a rainfall in 
excess of the average, the amount in October being very 
exceptional. 
February, May, June, July, August, September, November, 
and December had a rainfall below the average. 
The rainfall of October was very remarkable, no such 
an amount having fallen in this district between 1794 and 
1870, the largest amount registered being 7'793in. in 1843. 
In every year in which the rainfall has been above five 
inches in October, since 1794, excepting 1804, the rainfall 
for the year has considerably exceeded 30000in., and it 
appears to be very unusual to have a dry year with a very 
excessive rainfall in October.
