If the 250 inoculated had suffered to the same extent as the 124 uninoculat-
ed, they should have had 75 deaths instead of 20-a difference of 73.3 per cent.
From the above it would appear that uninoculated individuals living in the
same houses as those inoculated are a source of danger to them, and therefore
inoculated people are advised to see that those in immediate contact with them,
(i.e., family and servants) are likewise operated on. It is just as much a duty
to the public to be inoculated during plague prevalence, as to be vaccinated when
small-pox appears in the neighbourhood.
A striking illustration of the effect produced by the inoculation of an entire
community is afforded by the history of this epidemic among the Prsi inha-
bitants of Daman. The Prsi community of Lower Daman numbered 306.
Of these, 277 were inoculated and 29 were not. The following shows the
attacks and deaths in the two groups. No death from any other cause than
plague occurred in this community during the epidemic:-

If the inoculated, who were living in precisely the same social conditions as
the uninoculated had been affected in the same proportion, they should have had
38 deaths instead of only one, a difference of 97.4 per cent.
It should be noted that the solitary case of death among the inoculated
Prsis, had pain in the groin and fever at the time of inoculation-in fact, was
suffering from plague already manifest,-and therefore could not be expected to
derive benefit from the prophylactic.
3. Lanowli.-A small hill-station and railway dept at the top of the Bhor
Ght was the scene of the next demonstration. During the season, i.e., April
and May 1897, plague first appeared here, and about 20 cases occurred; then the
disease subsided, but only to re-appear in epidemic form after the onset of the
monsoon, at a time when, owing to the departure of summer visitors, the popu-
lation numbered only about 2,000. Operations were begun towards the end of
July, in C and D Wards of the town, these having been chosen by the local
Plague Committee for trial. A census having been made, inoculations were
begun on 24th July 1897, and continued daily, as opportunity arose, among the
friends and neighbours of those attacked. A daily house-to-house inspection
was kept up in these wards for weeks after this, and the figures given below
show the result obtained.
