By taking the differences between these extremes in each month, we 
find that the smallest difference is in December, viz., 2'51 in., and the 
largest in October, viz., 5*08 in. 
By comparing the consecutive numbers in Table XIV. together very 
large differences are found, the largest of these in each month are as 
follows :— 
In. 
In January between the 10th and 11th days, the difference is 2-65

By comparing the amounts of the falls at different periods of the 
year, it is at once seen that the heaviest take place in the months of 
May to November, and the lightest, in the early months of the year. 
The day in the year distinguished by the smallest fall is March 26, with 
O'84 in. for 44 years, the next in Order being January 8 and Fe¬ 
bruary 6. The day distinguished by the heaviest fall of the year is 
October 22, with 6’33 in. as the sum for 44 years; the next in order 
are September 28 and September 26, with 6T9 in. and 6’09 in. respec¬ 
tively. 
By taking the sums of the numbers in Table XIV. in five-day periods
