been 93.4°, the lowest 28.2o. affording a range of 65.2. The mean temperature
of the quarter was 55.1° and of the dew point was 45.3°, the mean
humidity only 70.2° (saturation being 100) so that although the usual
amount of rain fell, viz., 6.08 (or perhaps a little below the mean) yet
the air was unusually dry in each month. The month of April was about
an average temperature, May was about 1 degree below the average, and
June was nearly 6 degrees above it. The quantity of ozone registered
was about one fifth less than during the corresponding period of 1857.
The day on which the greatest heat occurred was the 16th. of June,
when it reached 93.4° at Hackney, 94.5° at Greenwich, 97.6° in the
Commercial Road, 94.8 at St, Thomas's Hospital, 94.9 at St. Mary's
Hospital, Paddington, and 92.0 at Hammersmith.
I remain,
Gentlemen,
Your obedient Servant,
JOHN W. TRIPE.
