I may at once say, there can be no doubt but that the increase is mainly
due to the reorganization of 1871 having increased the number of vacci-
nators and given to the department a most useful class of men, viz., the
assistant superintendents, who constantly see that the vaccinators do their
duty well.

Excess of operations over
the number of persons prima-
rily vaccinated.

6. There were 7,733 operations more than the number of persons
primarily vaccinated : that is to say, the vaccine
operation was performed that number of times
on persons who had been unsuccessfully operated
on at least once before.

Sex, caste, age and result.

7. The particulars as to sex, caste, and age are not recorded in
revaccination cases nor in secondary operations ;
there is thus the exact number of persons pri-
marily vaccinated shown in the columns for sex, caste, and age under
the heading of primary vaccination; but in the columns for result, both under
primary vaccinations and revaccinations, secondary operations are entered,
thus there are more operations than there are persons : this excess of opera-
tions is shown in a foot-note to the Statements No. I. and V. and also for the
native troops in No. VI.; but I am unable to give a similar foot-note for
British troops, as I get a return which only shows the successful cases ; and
for it I am indebted to the courtesy of Surgeon-Major Codrington, Secretary
to the Surgeon-General, Bombay Command.

Percentage of sex.

8. There were, exclusive of the European army returns, 329,865 males
and 294,831 females primarily vaccinated. The
proportion of the sexes in every hundred persons
is therefore 52.8 and 47.2 respectively. The disparity is greatest in Bombay
city where the males are 55 per cent. and it is lowest in the Western circle
where they are 50.3. There has been a gradual decline in the excess of males
over females during the past six years, with the exception of 1871-72. In
1866 the males exceeded females by 10 in every 100 persons, last year they
exceeded by 5.6. This decrease in the disparity of the sexes is due to the super-
intendents and their assistants impressing on the vaccinators that errors in
respect to the sexes will be punished as severly as any other errors arising from
carelessness.

Castes.

9. As regards castes, exclusive of the European and native armies' re-
turns, and taking the figures in Statements No. I.
and V., there were christians 3,281, hindús
454,915, musalmáns 114,745, pársis 1,216, and
other castes 44,874, or percentages of .53, 73.49, 18.53, .19 and 7.25 respec-
tively. I am unable to say whether these percentages bear any close relation
to the number of each caste in the general population, but there has not been
much difference in these percentages for several years back.

Age.

10. There has been a considerable annual increase in the number of in-
fantile vaccinations during the past six years with
the exception of 1870-71, but the percentage has
rather fallen ; the following figures are for six
years in civil life, viz. :—
