pregnancy, particularly hydatidiform mole and chorionepithelioma. A study is being undertaken, in collaboration with Professor Kreyberg of Oslo, on the grading of lung cancers. In bacteriology a survey has been made of the distribution of chromogenic mycobacteria and also a survey of anaerobic bacteria from clinical specimens, with special reference to the anaerobic non-spore- forming bacteria. At the same time work has continued on improvement of laboratory techniques in diagnostic bacteriology. During the year students and staff of the Department of Architecture examined the problems of cross-harbour transporta- tion, with special reference to a bridge across Lei Yue Mun, and its relationship to the Kai Tak flight path and the shipping channel. The staff were also concerned with a study for the new town at Tsuen Wan.
The Department of Engineering has developed a new simplified method of wind-stress analysis of tall buildings. A multi-storey building model is being made in the structures laboratory for study of the torsional effect of unsymmetrical building structures under wind load. Two FM (frequency modulation) antennas, Yagi and Zig-Zag, have been designed to meet the needs of the newly- constructed FM broadcasting station operated by Radio Hong Kong. Antennas have also been designed with the optimum efficiency at 92.5 mc/s, which is the average value of two transmit- ting frequencies used.
Research in the Department of Geography & Geology has been pursued in the investigation of mineral resources of Hong Kong, geological mapping, land-use surveys and on the industrial and economic geography. With the arrival of new staff future research will include development of communications in mainland China, the petrology of igneous rocks of the Hong Kong area and structural relationships in Hong Kong rocks.
Research is also being done on the Rare Books in the Fung Ping Shan Chinese Section of the Library. An annotated catalogue of these Rare Books is now in preparation.
ROYAL OBSERVATORY
Research and Applied Meteorology. There was a heavy demand for specialized investigations in the field of Applied Meteorology in 1960, which left little time for theoretical investigations.
