vaccine yield of each calf was raised by about 50 per cent., and the number of
calves to be maintained and vaccinated was reduced. The high potency of the
vaccine was further illustrated by the results of human vaccination received ;
the case and insertion success rates came to 99.77 and 98.05 per cent. respec-
tively. The year's work reflects great credit on the Director and staff of the
Institute.

10. The following table gives the results for different kinds of vaccine
lymph used :—

11.     The Deputy Sanitary Commissioners inspected 26,376 vaccinated
persons or 3.57 per cent. in 724 towns and villages and travelled 18,368 miles.
The Inspectors of Vaccination inspected 278,406 vaccinated persons in 10,607
towns and villages. Thus the results of 304,782 vaccinations or 41.27 per cent.
were checked by examination. The success rate for primary vaccination as
ascertained by Deputy Sanitary Commissioners was 99.06 and by Inspectors
98.93.

12.    A table showing the number of vaccinations under one year of age in
municipal towns is attached as appendix III.

13.    A diagram showing the proportion of population protected against
small-pox during the last seven years and the death-rate for small-pox during
1917-1918 is given as appendix IV.

14.    No instance of small-pox inoculation or of disease caused by vaccina-
tion was reported.

15.    The total cost of vaccination came to Rs. 3,81,828 against Rs. 3,63,682
in the previous year. This includes pay of Deputy Sanitary Commissioners
and the Vaccine Institute charges. The increase was due to rise in salaries
and the grant of grain compensation. The cost of each successful vaccination
was 9 annas against 8 annas and 10 pies last year.
