In addition, there is a mobile Mass Miniature Radiography Unit which operates throughout the Colony.
233. The quantity of work performed by the service continues to increase, the number of investigations carried out during the year having risen to 262,691. Increases have been most marked in the more specialized and time-consuming types of investiga-
tion.
284. Research has been continued on two projects, one being "The Morphology of the Female Chinese Pelvis" and the other on the relative efficiency of various types of contrast media.
Radiotherapeutic Section.
235. This is entirely centred on the Queen Mary Hospital. It is equipped with the following facilities:-
Deep Therapy-including a Telecobalt Therapy Unit Superficial Therapy
Contact Therapy Radium
The demands on the services of this section have become much in excess of its capabilities. Altogether 6,437 treatments were given, largely to patients suffering from carcinoma of the nasopharynx. This condition, which is very common in Hong Kong, is the subject of continued research in the department.
286. During the year the section has been fortunate enough to obtain the services of a physicist. His help is most essential both in working out dosages and in training students for the Diplomas in Medical Radiology and Therapeutics.

240. School health attendances totalled 4,797. 2,657 pairs of spectacles were glazed and issued from the department's own optical workshop.
Dental Service.
241. The Dental Sub-department is organized into two distinct branches providing;-
(a) The General Dental Service
and (b) The School Dental Service.
242. The General Dental Service is responsible for the treal- ment of monthly-paid Government officers and their families, a commitment which brings an estimated total of over 80,000 persons within this service. Only nine dental officers, including the Dental Specialist, are available for this commitment, and it has been inevitable that considerable delays have been experienced in providing comprehensive treatment. During the year a scheme has been introduced whereby Government officers and their families who so wish could go to private dentists and claim a rebate of 50% of the fees charged. In spite of this. numbers seeking treatment from the service have shown no notable falling off.
243. During the year 1956 Government employees made 15,499 viaita to dental clinics for examinations and treatment (an increase of 3,085 over 1965); members of families made 12,538 visits (an increase of 1,650).
244. The General Service, in addition to its treatment of Government officers and their families, is also responsible for the treatment of in-patients in Government hospitals, and prisoners in the Victoria, Stanley and Lai Chi Kok prisons.
