The strength of the affected jails is 12,525, the percentage of admissions
to strength 4.91, and of deaths to admissions 34. Of the 615 admissions
there were 6 in January, 47 in February, 145 in March, 243 in April, 72 in
May, 34 in June, 14 in July, 10 in August, 7 in September, 9 in October,
16 in November, and 12 in December.
Taking all the figures together, the monthly prevalence of the disease
is shown on the accompanying diagram. On the cholera map for 1864 are
marked the districts above shown to have been affected by the disease.
The incidence of cholera of 1864 among the troops and jails in Bengal
Province was considerably less than in the preceding year, but more consi-
derably greater than in the year before that. It more closely resembled in
point of frequency the cholera of 1861. The figures representing admissions
in each year from cholera among the troops and prison populations in the
Bengal Province for the four-yearly period ending 1864 are here reproduced,
with the figures for 1861 added for sake of comparison:-

The figures for the troops include the Europeans and natives. The
incidence of cholera among the troops and prisoners in jails is in no degree an
index to the actual prevalence of the disease among the civil population of
the same localities or districts. Cholera, as has often been observed, may be
raging with great fatality in a district or even in a town without affecting
the troops or prisoners dwelling in the same place. On the other hand, it is
very rare for the troops and prisoners to be affected by cholera without its
being at the same time more or less prevalent among the civil population.
