Thus in an average uninoculated population of 172, there occurred 12
cases, with 6 fatalities, while in an inoculated group living in exactly similar
circumstances, and averaging 147 in numbers, there were only 2 attacks and
no deaths at all.
This result, having become known, naturally encouraged the inhabitants
of Bombay City to apply for inoculation in large numbers, and during the
course of the season of plague prevalence, i.e., up to October 1897, altogether
8,142 persons were operated on. The following table shows that those inocu-
lated belonged to all castes and ages:-

In this early period in the introduction of inoculation, it is probable that
cases of plague appearing among those inoculated were promptly reported to the
Laboratory staff, as the whole medical profession in Bombay were watching its
effect with the keenest interest.
The reported number of attacks and deaths among the 8,142 inoculated
persons may therefore probably be taken as fairly accurate. Eighteen cases of
undoubted plague were thus reported and investigated by officers of the Labora-
tory. Of these 2 died and 16 recovered. The two former were ascertained
to have had the signs of the disease on them at the time of inoculation, and
therefore may be left out of account, as the operation does not profess to be
curative in this sense.
