The strength of the affected troops is 3,179, the percentage of admissions
to strength is 0·79, and of deaths to admissions 68. Of the 25 admissions
there were 3 in January, 3 in February, 5 in March, 8 in April, 3 in May, and
3 in June.
Among the jail populations-total average strength 16,751-there were
altogether 432 admissions and 170 deaths from cholera, giving a death-rate
of 10·15 per mille of strength. Of the 48 jails in the province, 35 recorded
cholera in 1870.
The strength of the 35 affected jails altogether is 13,893, the percentage
of admissions to strength 3·11, and of deaths to admissions 39. Of the 432
admissions there were 10 in January, 16 in February, 41 in March, 36 in
April, 17 in May, 19 in June, 184 in July, 49 in August, 46 in September,
5 in October, 7 in November, and 2 in December.
Taking all the figures together, the monthly prevalence of the disease is
shown in the accompanying diagram. The districts affected with cholera in
1870 are shown on the map for that year.
Compared with the returns for the preceding year, the incidence of the
cholera of 1870 among the troops and jail populations in this province is,
as was to be expected from the indications of the three-year cycle statistics
given in the review of 1868, considerably less than in the preceding year 1869,
which was the epidemic year of the next triennial period following that
ending with 1868. In the year 1869 the total of admissions from cholera
among the troops and jail populations in this province is 546, in 1870 the
total is 485, or including the admissions among the families of the European
soldiers, for the first time tabulated in this year, the total of cholera admission
is 501, still considerably below the figure of the epidemic year 1869.
Meteorology.-In the Howrah district the rainfall of 1870 was much
below the average, but the total amount measured, 54·43 inches, was so equally
