Table I.
London—Deaths under 1 Year in July, August, and part of September from Diarrhcea per 1,000,000 Population then Living at all Ages.
Years. | Mean temperature 10 weeks. | Temperature of Thames Water. | Age, 0.1. Deaths from Diarrhoea per 1,000,000 population living at all ages. |
---|---|---|---|
° | ° | ||
1860 | 58.1 | 6o.6 | 151 |
1862 | 59.0 | 62.0 | 189 |
1879 | 587 | 60.7 | 228 |
1877 | 61.2 | 63.3 | 347 |
1874 | 61.7 | 63.8 | 447 |
1878 | 63.7 | 64.1 | 576 |
1876 | 64.4 | 64.9 | 642 |
The deaths per 1,000,000 population in 1860 and 1862 were
proportionately smaller than in 1879, when the close approximation
of temperature is taken into account; but, with these
exceptions, the death.rate corresponds with great regularity to
the mean temperature of the air and of the Thames water. Thus
in 1860, with a mean temperature of 58.1°, we find an infantile
death.rate from diarrhcea of 151; and of 228 in 1879, with a
temperature of 58.7°, against only 189 in 1862, with a mean
temperature of 59.0°. In 1877, with a mean temperature of
the air of 61.2°, and of the Thames water of 63.3°, the death.
rate was 347 ; in 1874, with an air temperature of 61.7°, and of
the Thames of 63.8°, there was a mortality of 4.47; in 1878,
with an air temperature of 63.7°, and of the Thames of 64.1°,
the death.rate increased to 576; and in 1876, with an air temperature
of 64.4°, and of the Thames water of 64.9°, the death.
rate under one year from diarrhœa rose as high as 642 per
1,000,000 inhabitants living at all ages.
