No cases occurred during the months March to August, inclusive, and only one case in each
of the months September, October and January. Sixteen or 76.19 per cent. of the cases came
up for treatment during the last two months of the year. Further in the years 1893 and
1897, six cases of Filaria were diagnosed in the month of December and no others made their
appearance.
Temperature and moisture.—The climate of Saharanpur is that of the North-West
Provinces in general, modified by a northern position and proximity to the hills. It is at one
season tropical, at another almost European in character. The minimum temperature is about
37° in January, but the maximum on occasions may attain to 115° or even over. The tempe-
rature rises rapidly from the beginning of March and by the middle of June the maximum is
attained. The rains begin from about the end of June and last till the end of September,
but as in other parts of the country, they may exceptionally continue for another month.
