in 1796 and 1834. In February the weather was fine, aa until
the 24th there were only 3 days colder than usual, and the
mean temperature of the month was above 3 degrees in excess
of the average. March presented very similar meteorological
features, being unusually mild from the 4th to the 24th, after
which there was rather sharp cold. The mean for the month
was 3'4 degrees above the average. In April the weather was
pleasant at the beginning, but there was unusual cold subsequently,
so that the mean temperature was 2 degrees below the
average. In May it was 1.6 degrees above the mean, and in
June less than 1 degree above, with a prevalence of S.W. winds
and an excess of rain. In July, August and September the
mean temperature was nearly 3 degrees in excess, having been
+ 1.7 degrees in'July, + 4.4 degrees in August, and + 2.8
degrees in September, and the amount of rain was considerably
in defect, the total at Greenwich having been only 4½ inches,
against a mean of more than 7 inches. In October it was very
fine and dry, but the mean temperature was more than 1 degree
in defect, and the rain 17 inches below the average. November
and December were warm, the latter month having had a
temperature of nearly 2 degrees in exoess of the average.
I now present a table showing the highest, lowest and mean
temperatures, as well as the total rainfall at my house in the
Richmond Road, showing that the high temperature of 91.6
degrees was reached in August; 87.2 degrees in July; 83.4
degrees in September; 83.0 in June; and 80.8 in May. The
minimum temperature in any month of the year occurred in
November, when it was 25.8 degrees, or more than 6 degrees
below freezing point; 27.4 degrees in March; 27.6 in February;
and 29.0 in December, so that no very low temperature was
recorded during the year.
