Excerpt from Supplement to the Forty-Fifth Annual Report of the Registrar-General of Births, Deaths, and Marriages in England, 1885 The deaths from diarrhea fell from an annual rate of 1c76 pei' million to 935, showing an annual gain of 141 lives for each million persons living. But as the mortality from diarrhma is more directly and manifesti ati'ected by meteorological conditions than that from any other zymotic 'sease, it may be questioned whether the decline was not due to a series of com paratively favourable summers in the one deeennium as compared with the other, rather than to any sanitary measures that may have been adopted. In order to test this we must compare the summers 0 1861-70 with those of 1871-80; and as the great bulk of fatal diarrhma occurs in the interval between mid June and mid September, we may confine our comparison to that trimestrial period. Speaking generally, it appears from the returns of mortality in London that the diarrhoea mortality becomes high when the mean weekly temperature rises to about 63 F. Now in, the ten years 1861 - 70 there were altogether 317 days in the three summer months in which the mean temperature recorded at Greenwich was above 63 E, while in the next decennium the number of such days was 325. Adding together the excesses above 63 F. Of the 31{ da 3 in the first decennium, we have a total excess of 1153 degrees; whi e e total excess of the 335 hot days in the second decennium was 1 178 degrees. Measured, therefore, in this somewhat rough manner, the two decennia were practically on an equalityasreganlssuchtemperatureasmnybesupposedtoraisethe mortality from diarrhea; and such slight difference as the figures indicate is against the healthiness in this respect of the later decennium.
