73. Judging from the death returns the health of the Colony was not so good as in the previous year. The crude death rate was 25.02 per mille as compared with 24.39 the rate for 1931.
74. Respiratory diseases accounted for 43.05 per cent of the total deaths, the percentage for 1931 being 42.25.
75. The principal diseases causing death were broncho-pneumonia, pulmonary tuberculosis, bronchitis, pneumonia, infantile diarrhoea and diarrhoea.
76. The overcrowded houses combined with the expectorating habits of the Chinese furnish sufficient explanation for the prevalence of respiratory troubles.
77. One of the most important events in the public health year was the communication to the Sanitary Board of the recommendations of the Director of Medical and Sanitary Services for the reorganisation of the Medical and Sanitary Services of the Colony, and the debate on the subject by that Body.
78. The Sanitary Board agreed with all the recommendations except those bearing on the Sanitary Board and Public Health Advisory Board. They recommended that there be one Board for both objects,
Mosquito-borne Diseases.
79. The mosquito-borne diseases of the Colony are Malaria, Dengue and Filariasis. None of these are notifiable diseases and complete incidence figures are not available.
Malaria.
80. In the early days of the Colony malaria in Victoria was the chief cause of sickness and death and in 1844, coincident with the breaking of the soil for the formation of Queen's Road, the chief arterial road of the town, malaria became such a scourge that there were serious thoughts of abandoning the island.
81. Here as in Malaya disturbances of the soil often result in the formation of small collections of water which for reasons unknown attract the malaria mosquito and in which they deposit their eggs. The breaking of the soil is not a direct cause of malaria but a predisposing factor in a chain of events which favour the spread of the disease.
82. It would seem also that here as in Malaya the danger areas are not the large swamps and paddy fields remote from the hills, but collections of water within half a mile of the latter. Why it is so we do not know, but spring water which is not yet
