nearly all of which the mortality was doubled. In only three of these wards, however, the Eighth, Twelfth, and Sixteenth, in which the rate was 7 deaths to each 10,000 inhabitants living, was the mortality above the general rate for the city, which was 4 deaths in an equal population.

The deaths from t yphoid fever in this year of light- ened mortality were divided among the several quar- ters of the year in a quite unusual way; 97 occurred in the first quarter, 74 in the secon I, S'2 in the third, and 01 in the fourth. Hence the summer maximum, which I have shown in former reports to be a charac- teristic feature of the mortality from this disease in Philadelphia, disappeared, overwhelmed by the in- creased number of deaths accruing to the first and last quarters of the year. The diminished summer mortality coincided with a temperature somewhat lower than usual at this season, joined to an excessive rainfall, and followed upon a very cold January and February; while the comparatively high rate of the last quarter was the accompaniment of an opposite condition of things, exceptionally hot weather in Oc- tober, with deficient precipitation in this month and November. Though efforts are constantly being made to better the sanitary condition of the city, I cannot discover enough improvement to explain thereby the diminution in the mortality from typhoid fever since the year 1876 ; I have therefore been led to bring for- ward, as prominently as I have, the meteorological conditions upon which the fortunate change in recent years and last summer seems to have depended.
