panying abstract, from

of persons vaccinated.
This increase of work
has been general, the
Metropolitan circles

there has been a falling
off of 48,603. The
increase in the remain-
ing circles has been,—
Calcutta and Suburbs, 1,248; Darjeeling circle, 32,937; Ranchee circle,
28,600; Sonthal Pergunnahs, 1,898; and dispensary vaccination, 10,892, or a

The statement on the margin shows the amount of work done during the
last 10 years. There
is a most marked and
progressive increase
year by year, and
1871-72 is far in ad-
vance of any of its pre-
decessors. Still, taking
the population of these
provinces at 60 millions,
and the birth-rate at 30 per mille, the number of persons vaccinated amounts
only to about one-fifth of the births.
Summary of opera-
tions and success-
ful operations.
3. Table A. gives a summary of the work of the year in greater detail;
365,823 persons were vaccinated for the first time against 339,901—increase
25,922 ; and 9,468 re-vaccinated against 8,408—increase 1,050; the increase of
the latter was in Calcutta and its Suburbs. The number of persons successfully
vaccinated was 339,311 against 324,226—increase 15,085. The increase among
successful primary vaccinations was 15,321, while there was a decrease of
successful secondary vaccinations of 236. Thus the increase of persons success-
fully vaccinated was on the whole less than the increase of persons vaccinated by
11,887. This result is due to a marked fall in success in the Darjeeling circle,
where the percentage was 85.09 against 92.65, and to the greater number of
vaccinations and a smaller ratio of success in this class. Statement No. 1 shows
