On account of the larger number of persons vaccinated, the cost of each
successful case has fall-
en very considerably.
The decrease is com-
mon to all the circles
except Ranchee where
there is a slight rise.
The large number of
vaccinations performed
by an unpaid agency
in the Chota Nagpore
division has not been
taken into account.
11. Having now glanced at all the general points connected with the
results of last season's work, I shall offer some remarks on the reports and
returns of the several circles submitted by superintendents.

tions explained.
12. Calcutta and Suburbs.—The number of vaccinations performed in
Calcutta and its suburbs during the year 1872-73, exceeded those of the pre-
vious year by 10,948. Of this increase 1,692 belonged to the town, 2,938 to
the suburbs, and 6,318 to the cooly depôts; the numbers vaccinated in each
were 6,568, 9,807, and 15,108 respectively. Of the total number of operations
performed 46 per cent. were primary vaccinations, 54 per cent. secondary or
re-vaccinations. The proportions per cent. of primary and secondary vaccina-
tions in town, suburbs and cooly depôts were :—

Thus, while among the inhabitants of the town and suburbs rather less than
four-fifths were primary vaccinations, among coolies only a little above one-
tenth were primary, and a little under nine-tenths secondary operations. This
result is, no doubt, owing to the circumstance that all coolies passing through
the depôts are vaccinated, and that the great majority of them have already
been protected from small-pox in one way or other.
Successful vaccina-
tions
13. The number of persons successfully vaccinated during the season
amounted to 18,216 or nearly 58 per cent. of total operations. The numbers
of successful vaccinations and re-vaccinations bore to each other the ratios
per cent. of 78.8 and 21.2. The numbers of successful vaccinations and
re-vaccinations in town, suburbs and cooly depôts, were

It is satisfactory to find that while, on the whole, cases of successful vaccina-
tion constituted, for the reason above assigned, so small a proportion as 58 per
cent. of the whole number of operations performed, the success of primary
vaccination continues so high, the ratio being 99.51 against 99.58 in the
previous year. I entirely agree with Dr. Charles in thinking that a success of
ninety-nine in every hundred primary operations is most gratifying, and indi-
cates very careful work and supervision.
Number of opera-
tions performed
by each vaccina-
tor.
14. The number of operations performed by each vaccinator is 779 against
559. This indicates a decided improvement, but is owing to the larger number
