The vaccine used for the second series was much weaker than that previously
employed, as the laboratory was unable in this initial stage to meet the increas-
ing demands which arose on all hands. The results obtained therefore were
less successful as one would naturally expect. If the inoculated had suffered in
the same proportion as the uninoculated, they should have had 188 deaths instead
of 27-a difference of 85.6 per cent.

If the inoculated had suffered in the same proportion as the uninoculated,
they should have had 43 deaths instead of 3-a difference of 93 per cent.
Taking the period as a whole, the following is the result obtained :-
2,197 inoculated had 36 deaths, or 1.6 percent, of mortality.
6,033 not inoculated had 1,482 deaths or 24.6 per cent, of mortality.
As many familes in Daman were entirely inoculated, and so had no unin-
oculated individuals living with them for comparison, it was found necessary to
compare the whole inoculated population with all those not inoculated remaining
in the town. But if those houses be singled out in which only a portion of the
inhabitants had been inoculated, the following result is obtained in 62 such
cases :-
