Taking the average daily strength of the two groups and comparing them, it
is seen that 377 uninoculated had 78 cases with 57 deaths, while 323 inoculated
had 14 cases with 7 deaths. If the inoculated had suffered in the same proportion
as the uninoculated, they ought to have had 49 deaths, instead of 7-a difference
of 85.7 per cent.
4. Kirkee.-Plague broke out here in the artillery cantonment, situated 4
miles from Poona ; and the followers of the four batteries stationed there suffered
severely. These men were living with their families in lines on a sloping plain,
under Military discipline, and in circumstances far superior, in a sanitary sense,
to those of the average villager. When the disease appeared the lines were
isolated, so that none could enter or leave without the knowledge of the Military.
A special hospital was erected close by, where all sick persons were sent as they
were discovered by the search parties of European artillerymen, who visited
each house thrice daily. It is therefore probable that all cases of plague were
promptly discovered and removed to hospital, and in each case the usual
disinfection was thoroughly and systematically carried out. Yet, in spite of all
this, it was found that, in those not protected by inoculation, one out of every 6 of
the population was attacked, and 2 out of every 3 attacked, died. The epidemic
was therefore a severe one. The population of the lines numbered 1,530 ; and
out of these 671 volunteered for inoculation. At the close of the epidemic the
plague hospital admission and discharge book was examined, and compared with
the register of those inoculated, when  the following result was got. The
population operated on being under Military discipline, and confined to their
lines makes the accuracy of the figures undoubted.

Here, then, is seen a body of people divided into two groups by the fact
that one had undergone inoculation and the other not, but differing in no other
way, reacting towards plague in such a markedly different manner that the con-
clusion is forced on one that the inoculation must be the cause. Seeing the
absolute similarity of conditions, the 671 inoculated should have had proportion-
ately 112 cases and 77 deaths if they had remained as susceptible to the disease
as their uninoculated brothers, sisters, parents, wives, husbands, children ; but
