But these sums do not represent the 120 days of greatest rain, the 
sum of the falls from July 30 to November 26 being 415‘0 in.; and that 
from June 30 to October 27 is 421'5 in., which represents the greatest 
in the year. 
Collecting together the several periods of least rain, we find that— 
The 5-day period of least rain was from March 22nd to March 26th

Thus, all the periods of least falls of rain take place within the first 
120 days of the year. 
In like manner, collecting the periods of heaviest falls, we find that:— 
The 5-day period of heaviest rain 
was from October

By taking the means of the numbers in Table XIV. in each month, 
we find that the average sums of the falls of rain in 44 years :— 
In January 
2 45 inches per day 
,, February 
. . \ . 2-24 „ 
,, March

,, October

,, November

And by dividing these numbers by 44, we find the average fall per 
day in each month as follows:— 
In January ...... -056 inch per day
