    epidemic was comprised within a period of three weeks, that the nnmber of new cases rose rapidly to a maximum, and then nearly ao rapidly declined, the rise occupying a week, and the decline two weeks, and both rise and fall being little interrupted. On the other hand, the first epidemic of 1891 lasted about eight weeks, and that of 1891-2 about six weeks, and the course of both was marked by many fluctuations. It is to be noted, however, that each of these diagrams is based upon returns from a different number of hospitals ; the diagram in my first report including the cases in several hospitals from which I was not able to get lists for the later epidemics. It is likely that, had figures been obtainable from other hospitals, the fluctuations in the diagrams of the later epidemics would have been to some extent smoothed out. For the same reason, the figures of the diagrams cannot be taken as indicating the relative numbers of attacks in the several epidemics as compared one with another. For one numerously attended hospital, however,—viz., the Middlesex Hospital,—I am able, through the courtesy of Dr. Essex Wynter, Medical Registrar, to give in the following table the figures for each of the three late epidemics ; and it will be seen that they fully bear out the state- ments that the two later epidemics were less sudden in their development than that of ] 889-90, and that the cases were less numerous, but that the course of these later epidemics was more proti'acted and more fluctuating than that of the first.
