7. Different methods of vaccinations.—As usual, all vaccinations were performed
during the year with glycerinated lymph manufactured in the Vaccine Depôt at
Shillong.
8. Vaccination work in different districts —Out of 14 districts, ten reported an
increase in the total number of operations over those of the previous year. The in-
crease was the highest in the Kamrup district (+7,533), followed by Sylhet (+7,258),
Sibsagar (+4,897), Lakhimpur (+3,731), Darrang (+3,072), Nowgong (+2,853),
Lushai Hills ( + 1,753) and Manipur State (+1,593). In Kamrup the increase
is due to the increased number of vaccinators employed to deal with the wide-
spread outbreaks of small-pox in that district. Opposition to vaccination is still
very prevalent in this district and, to save the district from the repeated attacks of
small-pox, early opportunity will be taken this year (1925) to declare the refractory
villages in which small-pox is prevalent as small-pox infected areas under the
provisions of the regulations framed under the Epidemic Diseases Act. In- Sylhet
district, Habiganj and Karimganj Local Boards raised the number of their vacci-
nators by three and one respectively and the South Sylhet Local Board reduced
the number of its vaccinators by 2.
In Sibsagar a larger number of vaccinations was performed to check small-pox
which was sporadic throughout the year and assumed epidemic proportions from
December 1924. The increase in the Nowgong district is satisfactory as it shows that
vaccinations were done among Lalungs and Mahapurushias who hitherto showed
prejudice against the operation.
The Khasi and Jaintia Hills, Naga Hills, Garo Hills and Sadiya Frontier Tract
showed a fall in the number of operations varying from 183 in Sadiya Frontier Tract
to 692 in Khasi and Jaintia Hills.
9. Composition and strength of the Inspecting staff.—-The inspecting staff consist
of 8 Inspectors, 21 Sub-Inspectors and 1 chief vaccinator in Manipur State and were
the same as in the previous year.
10. Verification by the Inspecting staff.—Verification of the results of the work
done by the vaccinating staff was done by the superior inspecting staff who consist
of the district Civil Surgeons and their Assistant Surgeons including Assistant Surgeons
on Kala-azar duty.

The Director of Public Health inspected vaccinations in the Province generally,
while the Assistant Director of Public Health did so in the district of Sylhet. The
percentages of inspections by the superior inspecting staff, viz.—25.36 in primary and
16.60 in revaccination, in the Darrang district were the highest and 1.19 per cent.
and 1.44 per cent. respectively, in the Sylhet district were the lowest. The Sylhet
figures however do not include inspections made by the Assistant Director of Public
Health. The subordinate inspecting staff which consist of 8 Inspectors, 21 Sub-
