as well as 1,385 persons who attended to be vaccinated and 202 others who were examined as to their physical fitness for employment by Government. The numbers under these two last heads in 1921 were 510 and 131 respectively. Nationalities were represented as follows:- Europeans 2,262; Chinese 19,118; Portuguese 1,021; Indians 826; Japanese 156.
The Police.--The stations in Kowloon and the New Territories were visited by the medical officer from time to time throughout the year and reports made on matters requiring attention. The general health of the force has been good except that malaria was more prevalent than usual. This is referred to in another portion of the report. The stations were visited and inspected with a view to the prevention of this disease as far as possible, and I visited most of the stations in the Territory, as well as the medical officer. It is difficult to prevent malaria in a region full of rice fields and with countless pools, small and large; in fact, with every possible facility for the breeding of mosquitoes. But the main lines which ought to be followed to lessen the danger of infection were again recommended, such as the use of mosquito nets, wire gauze netting for rooms, the filling in of pools or the drainage of them; the use of kerosene oil for treating pools and the taking of quinine. But the men are exposed to being bitten on their patrols and the only one of the preventive measures which is then available is quinine, which is regularly given to all of the force at the stations. As far as is practicable most of the measures of prevention are carried out.
The Railway Staff--The health of this staff was good. Instruction in First Aid methods was given as in former years and twelve men obtained the certificate of the St. John's Ambulance Association; badges for proficiency in First Aid were awarded to fifteen men including those first referred to. To all of the railway stations and on the trains boxes containing the necessary equipment for rendering first aid, are supplied. Eleven persons were injured accidentally during the year and six of these were either killed outright or died subsequently from their injuries.
The Dispensary, Tai Po Market. This is in charge of a Chinese medical officer, Dr. Luk Chuen-hsuen who works under the supervision of the medical officer in charge of the New Territories. There was a slight increase in the attendances this year when 3,157 persons attended compared with 3,055 the year before, but the number of patients seeking advice at the dispensary has gradually increased since it was first opened. The vaccinations performed amounted to 1,074, and the number of cases diagnosed as suffering from malaria was 931 while 697 were so diagnosed last year. The first appointment of a Chinese medical officer to reside at Tai Po Market and carry on the dispensary there was made in February 1917. Before this the dispensary used to be in charge of a dispenser who merely dispensed domestic medicines. Although there have been several changes in the medical officers the number of Chinese patients who seek for advice and medicine
