32. In areas where the masses of the population reside, extensive training of hill streams has been carried out, and in consequence, as a rule, there are no facilities for the breeding of Anophelines, but where such exist as in suburban and rural areas on the Island and Mainland, the possibility of malaria must always be borne in mind.
33. Certain hill streams seem to occasion little if any malaria and a study of these might give valuable information for purposes of prevention in rural areas.
34. Examples of such streams are those crossing the Island Road; from its junction with Sassoon Road to Pokfulam village; the streams which flow from the Peak Hotel to Pokfulam Reservoir, from the War Memorial Hospital to Aberdeen and from Aberdeen Reservoir to the sea.
35. Malaria carrying mosquitoes have been found to breed in abandoned rice fields in hilly country; and during the last quarter of the year in rice cultivations whilst the irrigation water is draining off.
36. In Table IV, figures are given, regarding admissions, supplied by the following Hospitals: Government Civil, Kowloon, Victoria, Victoria Gaol, Laichikok Gaols (male and female), Tung Wah, Tung Wah Eastern, Kwong Wah, Matilda, Alice Memorial, War Memorial, Ho Mui Ling, and Yeung Wo. The malaria admissions are arranged according to the quarters of the year and to methods of diagnosis.
37. As malaria is not a notifiable disease rates cannot be given for the general population. Clinical diagnosis is not a satisfactory one.
38. One case of blackwater fever was reported.
39. In Table V statistics are shown of cases treated, supplied by the following Dispensaries: Tai Po, Un Long, Kowloon City, Sham Shui Po, Yaumati, Hunghom, Western Public, Shaukiwan, Aberdeen, Central and Eastern.
40. Table VI deals with Hospital admissions of Government servants (excluding coolies) in relation to admissions for malaria.
41. Table VII is a similar table for Police, including Water Police. Certain stations are situated in areas where malaria is not likely to be contracted, others in rural areas where night patrol work adds to the risk of infection.
42. Table VIII gives the results of examinations for malaria of blood films which were made from prisoners admitted to Victoria Gaol. The results are arranged in districts according to addresses supplied. The parasites are not classified as in the great majority of positive findings the diagnosis could only be made from the thick films and could not be established from the
