was 73,450 and was marked under "primary vaccination (including secondary
vaccination)," the decrease under this head being as many as 99,073 cases. The
districts which showed largest decreases were South Arcot (— 20,548), Guntūr
(—18,620), Tanjore (—17,116), Coimbatore (—16,734), Trichinopoly (—15,253),
and Vizagapatam (—11,600). The considerable fall during the year under report
is attributable to the following causes:—
(1) the changes in the subordinate vaccination staff effected by the
introduction of the new scheme which for a time seriously interfered with the
vaccination work ; and
(2) the prevalence of influenza during the second half of the year, for a
greater portion of which the work was practically at a standstill.
A few districts had increased number of primary vaccination cases. Pro
minent among them were South Kanara (+ 14,242) and Kistna (+ 10,622).
The increase under re-vaccination should be attributed to the greater
prevalence of smallpox in 1918 and the consequent demand for re-vaccination.

A regrettable decline is noticeable in the percentage of success both under
primary vaccination and re-vaccination during the year under report. Compared
with 1917-18, the fall under primary vaccination was 5.5 per cent and under
re-vaccination 8.8 per cent. Causes which led to this are sufficiently explained in
paragraph 7 of the report of the Director, King Institute, paragraph 9 of the
Northern Range Deputy Sanitary Commissioner's report and paragraph 4 (iv) of
the Southern Range Deputy Sanitary Commissioner's report, and it is hoped that
the defects on account of which the present state of things exists would be rectified
