The mortality from Scarlatina diminished from 138
in 1855 to 111 in 1856.
Hooping-cough, Croup, Thrush, Diarrhœa, Dysentery,
Cholera maintained nearly the same influence.
The deaths from Fever increased from 153 in 1855
to 225 in 1856.
This great difference in the Fever mortality of
1856 suggests a further analysis. The following Table
shews the Fever-deaths that occurred in each quarter.
It will be seen that the excess of mortality in 1856 took
place in the three first quarters, and especially in the
second or spring-quarter. This Table further shews that
the fatality of Fever was not increased by hot weather.
It may be inferred that the local determining causes
may be not less active in winter than in summer.
Diarrhoea, the other great test or touchstone of unhealthy
local conditions can only be applied during the
summer and autumn months. In Fever we possess a
constant index.
The deaths from Diarrhoea are distributed in quarters
for the year 1856 to shew how differently Fever and
Diarrhœa are affected by the same meteorological conditions.
Whilst 80 deaths were caused in the autumn or
hot quarter, only 27 occurred during the remaining three
quarters.
