marked decrease are Madras (5,956), Calicut (3,018), Ad6ni (1,035), Coimbatore
(867), Cochin (820), Vellore (566), Mangalore (521), Nandyal (273) and Srívilli¬
puttúr (266).
11. The municipalities which showed an increase are Ellore (571), Dindigul
(331), Vizagapatam (294), Conjeeveram (278), Negapatam (274) and Berhampur
(269).
12. Compulsory vaccination has been in force in some village unions of a few
districts throughout the year, in others for only a few months and in others again
not at all. It is as yet too early to say anything about its effects. All that is
known is that in some unions there has been a satisfactory increase in the number
of cases vaccinated, while in a few there has actually been a decrease. It is hoped
that shortly, on defects being fully ascertained, the representations of this office
will lead to use of a generally accepted system. Inefficient registration of births
and careless maintenance of " unprotected lists " are common defects.
13. The following table shows the comparative success obtained by the use of
different kinds of lymph in primary and secondary vaccination (re-vaccination

The chief point to be noticed is the progressive decrease in the number of
cases vaccinated from calf-to-arm and with lymph in tubes and plates unmixed with
preservatives. A more than complementary increase has occurred in the use of
lymph preserved with glycerine and lanoline. The lanoline lymph sent out from
the Bangalore Institute retains its superiority over both glycerine and lanoline
lymph locally prepared.
14. 18,359 deaths occurred from small-pox against 26,042 last year.
15. Seven Deputy Inspectors have failed to verify 50 per cent. of the cases
vaccinated in their ranges. The reasons given by them are, with certain reser-
vations, held to be satisfactory. Considering the amount of travelling they have
and the difficulty of doing office work in camp, I think it advisable that all Deputy
Inspectors of Vaccination should have a clerk, preferably a probationary vaccinator.
It tends also to act as an additional check against falsifications.
16. Out of 58 Deputy Inspectors of Vaccination, 22 are Certificated Sanitary
Inspectors, 1 having been appointed during the year under review. One Deputy
Inspector died, 2 retired and 8 were fined for carelessness.
17. The service books of all Deputy Inspectors of Vaccination have been
brought up to date.
I have the honour to be,
Sir,
Your most obedient servant,
J. W. CORNWALL, Captain, I.M.S.,
Ag. Inspector of Vaccination and
Deputy Sanitary Commissioner for Madras.
