       It is clear therefore that in this autumn there was no increase of mortality
beyond that more or less normal in India. And the year as far as Amritsar is con-
cerned may safely be considered a non-epidemic year.

       Though no study of the statistics at Delhi has been made it may be stated
that here also there was no serious mortality in 1909.

Spleen Rate and Parasite Rate.

       A community in Khazana, the children of which were examined at intervals,
gave in percentages the following results :—

  February
1909.		 April
1909.		 August
1909.		 October
1909.		 November
1909.
Infection over 100        2 ..  3  5  4
Infection over 20       25  7 14  5  8
Infection over 5         16  7 23 16 19
Infection under 5       28 39 23 31 27
Negative           28 47 36 42 42
Total percentage       72 53 63 58 58
Number of children       36 28 42 38 26

       The spleen rate in percentages among the same children were—

February           14 19 50  8   8 92 %
August            4 27 31 23 14 86 %
October            4 15 44 26 11 89 %
November            4   8 58 19   9 91 %
June 1910            0   5 29 38 28 72 %

       These figures show that whilst there are fluctuations especially as suggested
by the spleen rate in June 1910 after a very dry summer the spleen and parasite
rate in this community was always high.

       The spleen rate in Mahan Singh in February was 90 per cent. In August
1909 it was again exactly 90 per cent. In June 1910 it was 85 per cent. The
rates in February 1909 and June 1910 compared in detail are in percentages—

2 14 41 33 10 90 % 70
5 15 42 23 15 85 % 60

       The differences are very slight.

       Delhi was visited in February 1910. At this time in Ward XI the spleen
rate in percentages was as follows :—

20 25 40 15 0 100% 40
