REPORT OF VACCINATION IN BENGAL
one million by only 11,000 cases; but even had the number been reached, we should even
then have protected only a moiety of the requisite number, viz. 2,040,000, which we obtain by
taking the birth-rate at 30 per 1,000, and the population at 68 millions in the whole
province of Bengal.

4. Successful operations—These are shown in detail in table A in the appendix, and the
ratios of success in pri-
mary and secondary cases
in statement No. III.
Out of the total number
vaccinated, 919,770 were
successful, or 93.01 per
cent. This figure is
lower than that given in
the adjoining statement,
and is to be explained
by the following reason,
viz. that re-vaccination
always gives a much
lower rate of success.
Out of 25,276 re-vaccina-
tions included in the total
number of operations,
only 5,348, or about
21.49 per cent., were successful. It will be observed that the Calcutta, Metropolitan, and
Eastern Bengal circles, maintain their high percentages, and the superintendents vouch
for the accuracy of the figures from personal verifications. The Darjeeling and Sonthal
Pergunnahs circles, as well as the dispensaries, have improved their rates ; while the Ranchee
rate has decidedly declined. The provincial total is better than last year's. The ratio of
secondary, or re-vaccination, has declined by 2 per cent.

5. The number of operations performed by each vaccinator.—This is shown in statement
No. IV. The Metropolitan, Sonthal Pergunnahs,
Calcutta, and Darjeeling circles, show considerable
improvement; but the Ranchee and Eastern Bengal
ones a serious falling off. The Behar circle exhibits
better results than the new circle in Orissa, which
has done little work. The Metropolitan circles,
as usual, occupy the first place, and show an
average twice as great as that of the Sonthal Per-
gunnahs, which stands second in the list. This is
very creditable, and proves the thorough efficiency
of the Superintendent and his staff. The Sonthal
Pergunnahs circle shows an increase in its average
of more than double, as compared with the preceding
year's; and is clear proof that the staff, though reduced by one-half, worked most ener-
getically and successfully. The causes of the decrease in the Eastern Bengal and Ranchee
circles will be further noticed when I review their working separately. The mean of 950
per man is a fairly satisfactory figure.

6. Sex of the vaccinated.—The sex is registered of 772,900 persons ; of whom 406,419
were males, and 366,481
females, or 52.5 and 47.5
respectively, against 53.5
and 46.5 of the preced-
ing year, showing an
improvement in the pro-
portion of females vac-
cinated.
Dispensary
vaccination still shows a
smaller percentage of
females than the regular
circles
exhibit; but
the proportion this year
is higher than formerly;
and so far is a healthy
sign. Males preponderate
in every circle except that of Ranchee. The higher proportion of males in Calcutta is due
to the preponderance of male over female emigrants. In the Metropolitan circles the figures
remain much the same as in the preceding year. In the Darjeeling circle the proportion of
