Number successfully vacci-
nated per 1,000 of population.
26. The number successfully vaccinated per 1,000 of population was 30.93
against 31.44 in the preceding year, or a decrease of 0.51.
Compared with 1899-1900 the decrease is 4.68
Primary and re-vaccinations
in Feudatory States.
27. The total number of primary and re-vaccinations performed in Feuda-
tory States amounted to 68,738 and 18,818, respectively,
being an increase of 1,734 in the former and of 3,839 in
the latter as compared with the previous year. Compared with the year 1899¬
1900 there was a decrease of 13,311 under " Primary " and an increase of 12,726
under " Re-vaccination."
28. The large increase in the number of re-vaccinations is due to this work
having been started in certain villages of the Patna State, in which it had never
before been attempted; to special attention having been paid to certain villages
of the Kalahandi State in which small-pox was prevalent; and to the general
improvement in the public health permitting a freer recourse to the operation.
29. The percentage of success claimed by Vaccinators is 95.93 in primary
vaccination and 86.34 in re-vaccination as compared with 96.23 and 84.02, res-
pectively, in 1900-1901. In 1899-1900 it was 95.82 in primary and 92.42 in
re-vaccinations.
Lymph cultivation
30. During the non-working season, in almost all the districts, the supply of
lymph was kept up at Head-Quarters by arm-to-arm
vaccination or by buffalo-calf retro-vaccination ; and this
was issued to Vaccinators to commence the work of the season. The Vaccinators
subsequently maintained their supply of lymph by vaccinating cow or buffalo
calves in the interior of the district.
31. In November last, Colonel Scott Reid ascertained, during his visit to
the Nimar District, that vaccination with glycerinated lymph, prepared locally,
was being carried on with marked success, and that most, if not all, the difficul-
ties formerly experienced in this method had been overcome; he thereupon
obtained from the Civil Surgeon (Major Banatvala) a note describing the exact
mode of preparation adopted and circulated it to all Civil Surgeons in the Pro-
vince for guidance. The results from the use of this lymph in 1901-02 show
a marked improvement, the percentage of success being 90.96 as compared with
86.97 and 86.27 in the two preceding years.
Calf vaccination.
32. 9,922 calves were vaccinated in the Province with the following results.—
successful 9,037 unsuccessful 679, rejected on account of
suppuration or excessive inflammation 206.
Cost incurred in the cultiva-
tion of lymph.
33. The total cost incurred in the cultivation of lymph was Rs. 184-1-6
against Rs. 311-12-3 in the previous year. In the year
1899-1900 it was Rs. 97-13-0.
Operations performed with
different kinds of lymph.
34. The following table shows the different kinds of lymph used in
vaccinating children and the results attained in each of
the years comprised in the triennial period :—
