The strength of the affected jails is 12,978, the percentage of admissions
to strength 2.23, and of deaths to admissions 41. Of the 289 admissions
there were 2 in January, 11 in February, 29 in March, 60 in April, 60 in
May, 16 in June, 13 in July, 13 in August, 5 in September, 9 in October, 39
in November and 32 in December.
Taking all the figures together, the monthly prevalence of the disease
is shown in the accompanying diagram. On the map are marked the districts
which are known to have been affected with cholera in 1868.
Judging from its incidence among the troops and jail populations, the cholera
of 1868 in Bengal Province was no more than the ordinary manifestation
of the disease in non-epidemic years; and in point of prevalence it appears
from the army and jail returns, to have fallen to a minimum of the triennial
period, 1866 to 1868, inclusive. This triennial periodicity in the activity
and subsidence alternately of the cholera of this Bengal Province is very
clearly marked in the army and jail returns, as is shown in the subjoined
abstract statement of admissions from cholera among the troops and jail
populations in the Bengal Province for the series of five triennial periods, as
taken from Bryden's Tables. '
