to the fact that in the two previous years a large number of unprotected
children were vaccinated, the Special Inspector of Vaccination for Orissa
having worked in the backward portions of the district during those years.
As regards the decrease in Manbnum and Singhbhum, no satisfactory explana-
tion has been furnished by the Civil Surgeons.
Vaccination in Municipalities.
5. In the Calcutta Municipality 33,985 operations were performed during
the year, against 82,079 in 1908-09 and 31,155 in
1907-08. The large increase in 1908-09 was due
to the epidemic outbreak of small pox in the town.
In mufassal municipalities, dispensaries, etc., the number of cases amounted
to 129,971, against 142,781 of the previous year. The decrease is due to much
less prevalence of small-pox during the year render review. The average
work of a vaccinator in mufassal municipalities was 735 against 819, while
that of licensed, District Board and all other paid vaccinators was 1,047,
1,866 and 1,166, against 1,022, 1,979 and 1,475, respectively, of the previous
year.
Protection afforded to infants.
6. During the year under review, out of 1,611,332, the estimated number
of infants under one year available for vaccina-
tion 934,181, that is, 579.75 per thousand were
successfully vaccinated, against 566.72 in the previous year. In 24 districts
(against 22 of the previous year), viz., Ranchi, Sambalpur, Birbhum, Palamau,
Murshidabad, Bhagalpur, Darjeeling, Cuttack, Champaran, Sonthal Parganas,
Hazaribagh, Puri, Manbhum, Burdwan, Nadia, Monghyr, Darbhanga, Purnea,
Jessore, Midnapore, Gaya, Angul, Saran and 24-Parganas, the protection was
over 500 per mille, which is very satisfactory, considering that vaccination is
not compulsory in rural areas.
The protection afforded to infants in municipalities is shown in Appendix
VII attached to the report. It will be seen that the protection afforded was
799.98 per mille of the surviving infant population, against 942.30 of the pre-
vious year. The high rates of protection of last year was chiefly due to the
epidemic outbreak of small-pox in Calcutta and several other towns when a
large number of infants were vaccinated. The attention of the Civil Surgeons
has as usual been drawn to their responsibility in the matter of infant vaccina-
tion in towns where the protection is inadequate.
Recess work.
7. During the recess or non-working season of the past year, 276,417
operations were performed in connection with
small-pox epidemics, against 181,243 in 1908-09.

8. The total number of successful primary and revaccination operations
in six-points was 822,512 and 20,061 respectively,
against 825,233 and 19,670 respectively of the
previous year.
Factory and tea-garden vaccina-
tion.
9. During the year under review the total number of primary and re-
vaccination operations performed in factories and
tea-gardens in Bengal was 3,961 and 671 respec-
tively, against 2,945 and 1,403 respectively in the
previous year. The ratio of success in primary and re-vaccination cases was
95.22 and 63.78 respectively.

against Rs. 2,05,947-12-7 of the previous year.

nation was one anna and nine pies, against one
anna and eight pies of the previous year.
