Table of Notifiable masses. It will be observed that Tuberculosing is not included among these diseases, but in view of its considerable incidence (*.g. in Tung Wah Hospital 656 sasen with a mortality of 50%, see page 24) it would appear desirable that it should be so included in order that, if possible, early infuctions may be removed from insanitary or evercrowded surroundings, the latter being aubsequently disinfected, and advanced onses may be isolated to prevent their acting as continuous seurass of infection.

kostuite prevention. In view of the known presence of Stegenyia fasciata in Visteria and the Kowisen districts (see page 18 of Hedion) Report), and the importance of this mesquite from its connection with yellow fever in other parts, steps should be taken to minimise or do away with its breeding
pluses, wherever possible. Its well known habits as a
semi-domesticated mosquite indiante the lines on which steps
should be taken. Thorough house-to-house inspections at
regular short intervals should be made by Banitary Inspecters
in their districts to ensure that all receptacles used for the
storing of water are covered and protasted from rocess for the
deposition of aggs, and that exves-gutters and rain water
pipes etc. shall not wontain residual water in which mosquitos
may breed. "Konquite-larvae Indexes", showing the percentage of infested to uninfested houses should be prepared and issued /

It is clear that the floating character of the
population of Hong Kong, especially among the Chinese, must prevent the formation of reliable Fealth Statistics, while de incomplete registration of Chinese births, renders impossible the calculation of the Infantile Mortality. Such figurOI 28 ATE
