during the period of quarantine and were ultimately found to be

METEOROLOGY FOR THE YEAR 1899.
By the access kindly afforded to the registers of temperature,
rainfall, &c. recorded in Battersea Park, I am able to give a few
interesting particulars concerning the Meteorology of the year.
Temperature. The highest temperature recorded was during the
third week in July, when the thermometer registered
104°, the lowest temperature being 20°, which was recorded in
the fourth week of March. The greatest variation recorded by
the thermometer was during the first week in June, the minimum
being 37° and the maximum 96°, representing a variation of 55.°
The least variation was in the second week of December, the
maximum temperature being 38° and the minimum 21°,
representing a variation of 17°.
In the chart of Meteorology of the year will be found the
minimum and maximum temperature recorded during each week
of the year at Battersea and the mean temperature of each week
as recorded at Greenwich. Reference has already been made
on page 45 to the apparent similarity in the variation of the
lines indicating the temperature and those representing the
prevalence of notifiable infectious disease.
Rainfall. The recorded rainfall for the whole year was 22.8
inches, representing an average weekly rainfall of
0.43 inches. During the first three weeks of June no rainfall
was recorded, being the longest period during the year
wherein there was complete absence of rainfall. The 8th, 9th,
10th, 11th and 12th weeks in the year, however, represented the
longest period of drought, less than 1/10of an inch being recorded
