Rainfall.— Tor the first time in the four years, indeed the first 
time in nine years, i.e. since 1874, the rainfall was below the 
mean for 1870-79; February showing the greatest excess, 
December the greatest deficiency above and below that mean. 
September, however, had the heaviest fall; July being also a wet 
month. Dry 'periods .—In April there was no rain at all until the 
18th ; nor, if we except a T S on May 26th, was there any rain 
between May 14th and June 15th. Wet periods. —Feb. 7—10, 
when 1"56 fell; April 27—29, when F36 fell; July 20—23, 
when 1'50 fell; and the last four days of September, when 2-25 fell. 
The seasons of 1882-83 are given in the usual table: —

Comparing this table of seasons with that of preceding years, we 
find that the winter of 1882-83 was the warmest and the wettest, 
with the greatest range of temperature; the spring was the 
coldest with the greatest range of temperature; the summer 
differed materially from its three predecessors; whilst the autumn 
again showed the highest temperature, and the greatest range. We 
may therefore, from this table, characterize the seasons thus: — 
Winter, mild and wet; spring, cold and somewhat dry ; summer, 
rather wet and dull; autumn, warm and humid. 
It only remains now to give a few notes on the months, using 
the usual abbreviations as given in Beaufort’s scale. I may add 
that the accumulated temperature, which is a new feature in my 
report, is calculated approximately from the mean, max., and min., 
for each month, and indicates the combined amount and duration of 
the excess or defect of temperature above or below 42°, the
