and the cost of each successful case fell from As. 6 to As. 5-1. Infantile vaccination
also made fair progress, 81.8 per cent. of the children born during the year having
been successfully vaccinated against 69 per cent. in the previous year. The Govern-
ment trusts that the progress made will be maintained in the current and future
years.
8. Vaccination with animal lymph.—All the operations were performed with
animal lymph and the following statement shows the results of calf-to-arm vaccination,
vaccination with lymph preserved in tubes, glycerine paste and lanoline paste, as
compared with those of the previous two years :—

As in previous years, the percentage of success was highest in the case of calf-to-
arm vaccination. The rate of success obtained with lymph preserved with glycerine,
which was used in more than half the number of cases, was only 85.6 per cent.
against 95.5 in the case of fresh lymph. It is, however, noteworthy that the percentage
of success obtained with lymph preserved with lanoline, which used to be higher than
that obtained with glycerine paste, showed a considerable fall during the year, being
only 82.0 per cent. against 90.5 in 1896-97 and 94.3 in 1895-96. No explanation
of this has been offered in the report.
9. Mortality from small-pox.—The number of deaths from small-pox was 23,959,
or nearly double the figure recorded for the previous year, namely, 12,218. As in
1896-97, the majority of the cases (16,868) occurred in the district of Ganjám, in which
vigorous measures are reported to have been taken to push forward vaccination. From
the diagrams referred to in paragraph 21 of the report, it will be seen that about
4,000 in every 10,000 of the population were protected in the district of Tinnevelly
and more than 3,000 in the Nilgiris, Chingleput, Salem, South Arcot and Bellary,
while in Malabar the number was less than 2,000. Among municipalities, the number
of persons so protected varied from 9,200 in Coonoor to 500 in Tiruvannámalai.
These variations show conclusively that the progress of vaccination in different
districts and municipalities has not been uniform and that there is much scope
for improvement. It appears from the same diagrams that the highest rates of morta-
lity from small-pox occurred in the two districts, Malabar and Ganjám, where the
population was least protected by vaccination.
10. The proposal made by the Inspector of Vaccination in his letter referred to
in paragraph 25 of the report has been disposed of in G.O., No. 1219 L., dated 5th
July 1898.
