England and Wales.—During the first two of these decennial periods 
(Table II.) the returns are not very numerous; so that the effect of this 
grouping is scarcely so manifest as in the period 1850-59. In the period 
1830-39, only one return is available for the group “55 to 60 in.,” and 
none at all for higher amounts. Nevertheless a comparison of the values : 
from that station with those from the “20 to 25-in.” group shows de- ' 
cidedly the tendency to a winter maximum in the former, and a summer 
maximum in the latter. In looking down the tabulations for 1840-49 and 
1850-59, the gradual drawing of the larger percentages from the middle to 
the right-hand columns as the annual fall in each district increases, is evident 
ata glance; and in the groups for the highest amounts, the maximum is ‘ 
found to have passed on to the January column, and at some places even the 
February value is much increased. 
It is.much to be regretted that the rain-gauges were so unevenly distributed 
over the country that it is almost useless to attempt the intercomparison of 
groups of similar value in the different districts. There appears, however, at 
first sight reason for believing that, in groups of the same actual annual rain- 
fall, the maximum monthly proportion occurs rather later in the year in the 
eastern districts than in the western. 
Another peculiarity shown by these Tables is this ; the period of minimum 
monthly fall also advances to a later period of the year the greater the annual 
rainfall, though to a less extent than the maximum. In places where the 
fall is small, the minimum is usually found in February or March, whilst in
