lanolinated and glycerinated, which was manufactured at the Vaccine Depôt,
Belgaum, was carried on successfully, and he remarks that the increase in the
work cannot be attributed to a fall in the epidemicity of plague but rather to vacci-
nation with preserved vaccine, lessening the difficulties confronting the vacci-
nator and also possibly to the new method being more popular with the people.

Training of Inspectors and
Vaccinators in preserved
lymph work at Belgaum
Vaccine Depôt.

25. The number of Inspectors and Vaccinators
trained at the Belgaum Vaccine Depôt was 98, of
these 41 were from the Southern Registration District,
23 from the Central Registration District, 22 from the
Western Registration District and 12 from the
Gujarát Registration District.

The Vaccinators, who have received training at the Belgaum Depôt, are
being regularly supplied with preserved lymph from Belgaum and are working
with it in their respective districts.

26. The following table shows the different kinds of lymph used, the
work done with each kind and the comparative results obtained :—

Lymph.

27. The quality of lymph in use throughout the year was on the whole
good. Glycerinated lymph was obtained on two occasions
from England by the Deputy Sanitary Commissioner,
Southern Registration District, and was tried on calves with excellent results.

28. No inoculation was reported to have been practised anywhere in the
Presidency.

29. No instances were reported of any disease having been communicated
through vaccination.

30.    The table showing the number of children under one year of age in
towns available for vaccination is given in Appendix III.

31.    The trials made at the Belgaum Depôt with various kinds of preserved
lymph have resulted in the adoption of chloroformed glycerinated vaccine. This
vaccine can be rapidly freed from extraneous organisms in preparation and
yields the most satisfactory results. It has been largely used throughout the
Southern Registration District during the year and is being gradually intro-
duced into the other districts.

32.     The comparative results obtained with human and glycerinated
lymph, as shown in the table, are unfavourable to the latter, but the skill
displayed by Vaccinators varies greatly, and it has been shown by Captain
Hutchinson in the Annual Report of the Vaccine Depôt that the failures and
bad results are confined to a small proportion of the Vaccinators who have
been using the new lymph. Excluding these, the results show a case success
rate of 98.74 per cent. and an insertion success rate of 94.71 per cent.

33.    The success obtained from the use of preserved lymph has advanced
the scheme for a Central Vaccine Depôt beyond the experimental stage and
warrants the introduction of the new method throughout the Presidency.
