From these tables it will appear that the spleen-rate is liable to fluc-
tuation and that in spite of the malaria incidence being so high this year some
places show a lower spleen-rate figure. Factors that have some bearing on
these results are (1) the eastern half of the province escaped the epidemic and
(2) the introduction of quininisation as a prophylactic into schools.
29. A high spleen-rate extending over a series of years presupposes
endemic centres, and as they in turn are likely to be the seats of epidemics
when other conditions are favourable it is necessary to keep them under close
observation.
30. The spleen-rate has been steadily on the increase in Montgomery,
and the parasite-rate has increased in both it and Mianwali since canal water
was introduced. The following table has been introduced to show this and also
the marked difference between the conditions existing in the civil station of
Mianwali and the town to which irrigation has not been extended.
