As I mentioned above it will be noticed that amongst children, females have been attacked more than males, the proportion being 51.1 per cent. females to 48.8 per cent. males. This difference is most noticeable in the age period 0 to 1 year in which the female cases are 58.6 per cent. of the whole. In the next age period the proportion of females is 44.5 per cent. but it makes a jump up in the next age period 5-15 years, the figure for this period being 53.0 per cent.
Between the ages of 15 and 60 years, the proportion of females has kept fairly constant, but above 60 years the figure suddenly rises again.
In the age period 15 to 25 years, it will be noticed that the percentage of female cases is 29.3. As it has been computed that the Chinese female population numbers 27.1 per cent, and the non-Chinese a percentage of 30 out of the whole population, this figure 29.3 is just what might have been expected.
At the age periods 25 to 45 and 45 to 60 years the percentage of female cases is somewhat diminished, being 22.4. As these age periods are those in which one would find the majority of labourers, it is not surprising that the pro- portion of females to males should have diminished.
The lowest figure is that for European females, in which class there were 5 cases but no deaths. The rate for European males and females is still the lowest in the Table (11.76). Of the Europeans who died, one was an imported case (from Canton), one was a broken-down European living in the Native quarter, another was a heavy drinker and said to have been suffering from alcoholism for several days prior to his death, and the other was the case of an Engineer who fell into a dock and killed himself, but who on examination was found to have been suffering from the septic form of Plague. The Chinese cominunity shew not only the highest percentage mortality (93.25 %) but also the highest figure for each sex, the male mortality being 91.9 per cent. and the female 95.7 per cent. ality shewing the next highest death-rate is the Japanese with a percentage morta- lity of 64.2. Then come Indians with 48.8 per cent.; Portuguese with 40.9 per cent, and other nationalities with 40 per cent.
