two other records (5‘95 in ’76 and 4’87 in ’82) higher than 
any other inontli from November to May. The August least 
fall is exceptionally high, and so, also, its least number of 
days. October and November stand next, and stand high for 
“ most days.” Here, however, December, 1868, ranks highest 
with 29 days ; whereas, in May, 20 days is the utmost in any 
year. Twice in April (’4.2 and ’55) it rained only twice. 
This also happened in July, 1868. 
An examination of the four rainiest months, July to 
October, shows rather curious results. The cumulative totals 
for the 50 years, correcting September up to 61 days, are 
within 7| per cent, of each other, the totals being 133 17, 
134’25, 124’14, and 130’89. O’he ditference between the three 
higher values (July, August, October) is extraordinarily small. 
In 1886 it was even less, under an inch. Then October was 
ahead for a year, then Julj^ for two years, August only 
creeping again to the front in 1890 
Yet August may undoubtedly be regarded as the wettest 
month. Previousl}' to 1886 it had ranked first since 1857 and 
was also ahead in 1845. In 1868 it was 11 inches ahead on 
80. Altogether, August was in front in 31| years, July in 10, 
October in 85 , September never. Yet, in the wet decade 
1871 — 80, most Pain fell in September, giving a total of 33 55 
actual, or 34'67, corrected. Moieover, this is the greatest fall 
for any month in any decade, averaging more than an inch per 
year, that is, 40 per cent., above the 50 years’ mean. 
In consequence of this, in 1881, September, when corrected 
for its one less day, stood above both July and October, being 
only a little more than tliree inches behind August. 
A comparison of Painfall and Days with Rain shows that 
we must ascribe the wetness of July and August to the heavy 
falls, and of October to a combination of this and the number 
of Days with Rain. 
The two following tables give the mean Rain and mean 
Days with Rain for each of the fire decades.
