shown, by a study of mortality figures, to have occurred in the Punjab. This
is best shown by taking the mean of the deaths recorded throughout the
decennium for some month which seems to have been free from special
epidemic conditions, treating this figure as one, and subjecting the mortality
figures for the different months of the different years to division by it, in order
to see whether a high multiple of one is anywhere obtained.
In the following table the deaths for the different months of the
different years of the decennium, less the deaths from the Special Diseases, are
given, those figures which are less than ten per cent, above the mean of their
particular month having been expunged, to show up the others more clearly :-

June being the month in which the Death-rate minus the rate for
Special Diseases is lowest, its mean for the decennium may be taken as one.
In the next table the figures for the first table have been corrected so as to be
figures for months of thirty days. They have then been divided by the mean
of the figures for June, and the result is as shown. The figures for the rainfall
at Thána for the years of the decennium have been inserted at the left hand
side of the table, the rainfall for 1899 and 1900 also being given :-

Nothing that could be called an actual Epidemic Eigure is to be seen,
and it may be concluded that, although variations in the intensity of Malaria
did occur, Malaria did not visit Salsette in Epidemic form during the de-
cennium.
