No. 1498 L., 28TH JULY 1899.
99.5 and in re-vaccinations 83.2, the corresponding figures for the previous year being
99.6 and 87.0, and the average cost of each successful case rose from As. 5-1 to
As. 6-2. Infantile vaccination also showed a retrogression, only 70.9 per cent. of
the children born during the year against 81.8 in 1897-98 having been successfully
vaccinated. No explanation has been given for these comparatively poor results; but
they were evidently due to the plague inoculation scare which generally prevailed
during the year. The Government trusts that an improvement will be shown in the
current year.
8. Vaccination with animal lymph. —As in the previous year, all the operations
were performed with animal lymph, and the results of calf-to-arm vaccination, vaccina-
tion with animal lymph preserved in tubes or plates, glycerine paste and lanoline
paste are shown in the following statement:—

* The difference as compared with the figures given in the reviews of the reports for 1896-97 and 1897-98 is due to
the fact that the number of cases the results of which were unknown, was then included in, whereas it has now been
deducted from, the total number of vaccinations, in calculating the percentage of success.
The percentage of success was, as in previous years, highest (97.2) in the case of calf-
to-arm vaccination, while the rate obtained with lymph preserved with glycerine,
which was used in more than 40 per cent. of the total number of operations, was
lowest, being 82.8 per cent. against 88.1 in the previous year. The percentage of
success in the case of lymph preserved in glass tubes or plates rose from 95.3 to 95.6,
and that in the case of lymph preserved with lanoline from 86.6 to 87.9.
9. Mortality from small-pox.—There were only 12,173 deaths from small-pox, or
11,786 less than in the previous year. From the diagrams referred to in paragraph 22
of the report, it appears that out of every 10,000 inhabitants, about 4,000 may be
regarded as protected from small-pox in the district of the Nilgiris and more than
3,000 in the districts of Tinnevelly, Chingleput, Salem, South Canara and Bellary,
while in Malabar the number continued to be less than 2,000 and in Ganjám a little
above it. As might be expected, the highest rates of mortality from small-pox were
recorded in the two districts last named. Turning to Municipalities, the number of
persons protected per 10,000 of the population varied from 9,400 in Coonoor to 1,000
in Tiruvannámalai. In Srívilliputtúr and Chingleput also, the number was small,
being less than 1,500.
