OFFICE OF SANITARY COMMISSIONER,
                                                            FORT ST. GEORGE,
                                                                  20th June 1892.
                              No. 1798 A./S.

From

                        SURGEON LIEUT.-COL. J. A. LAING,

                                          Sanitary Commissioner for Madras,

To

                        THE CHIEF SECRETARY TO GOVERNMENT,

                                    LOCAL AND MUNICIPAL DEPARTMENT.

SIR,

I HAVE the honour to forward the Vaccination Report for the past official year.

2. During the year under review 820 vaccinators were employed or 9 more
than in the previous year. The number of Deputy Inspectors of Vaccination, viz.,
57, was the same as in 1890-91.

3.  It is satisfactory to notice the increase in the number
of vaccinations during 1891-92, a progressive improvement
having steadily taken place since the year 1886 as shown in the
margin.

4.   Of the total number of operations performed, 996,274
were primary with success in 927,719 cases (93.1 per cent. or
1.0 less than the corresponding ratio for 1890-91), and 57,146
were re-vaccinations with success in 42,785 cases (74.9 per
cent. against 80.6 in the previous year).

5.   In only three districts, viz., Coimbatore, Kurnool and Trichinopoly, was
there a decrease in the number of operations when compared with last year's
figures. The district of Trichinopoly shows the greatest decrease, 33,919 cases
having been vaccinated in 1891-92 against 38,812 in 1890-91. In the Tinnevelly
District there was a large increase in the number of operations, 69,085 cases being
vaccinated in 1891-92 against 56,112 in 1890-91. The percentage of success in
districts was 93.0 or 1.5 less than in the previous year, and was no doubt chiefly
due to the changes made in the kind of lymph used.

6.  The average number of operations performed by each man was 1,220 in
1891-92 against 1,120 in the previous year. The largest number of operations
performed by each vaccinator was 2,490 in the Kurnool District, and the lowest
822 in the Nílgiris.

7.  Vaccination was compulsory at the end of 1891-92 in 48 municipalities,
having been introduced into 9 in the course of the year under review. The total
number of operations was 110,590 in 1891-92 against 99,058 in 1890-91.

8.  The total number of cases verified by Deputy Inspectors of Vaccination
was 524,571 against 482,170 in the previous year. In six ranges against ten in
1890-91 the deputies failed to verify 50 per cent. of the cases vaccinated.

Operations with animal lymph were conducted to varying extents in all the
districts and municipalities. During the year there were 674,148 operations done
with animal lymph or 64.0 per cent. of the total number vaccinated. The percentage
of success varied with the different forms of lymph employed. The best results were
obtained with fresh lymph direct from the calf, the rate of success being 96.4 per
cent.; next that from preserved animal lymph with a percentage of 93.5, and the
lowest results were those done with lanoline paste, the rate of success being 89.3.

                                                            I have the honour to be,
                                                                        Sir,
                                                            Your most obedient servant,

                                                                  J. A. LAING, Surgeon Lieut.-Col.,

                                                                              Sanitary Commissioner for Madras.
