It is a lamentable observation that the majority of thin films reaching the Laboratory are atrociously badly made and one wonders whether the Schools of Medicine pay sufficient attention to this small but important point in the technical equipment of their graduates.

Judging by the work on filarial infection of mosquitoes being reported by the Malariologist, Dr. R. B. Jackson, it is quite possible that if night films were sent for examination more frequently the proportion of positives might be surprisingly high. In view of the intimate association of the late Sir Patrick Manson with filariasis, it would be most fitting if problems connected with this disease were investigated thoroughly in the place where his first work in the East was done.
(3) Faeces-Six hundred and ninety-seven samples of faeces were examined for the presence of helminths and protozoa. Such examinations are noteworthy for the extremely high infestation rate with Clonorchis; the presence of ova of this parasite may almost be said to be the hall-mark of Hong Kong excreta.
B. SEROLOGY.
(1) Serological reaction for Syphilis.-Six thousand four hundred and forty-two sera were subjected to test. As compared with previous years a great increase may be noted, due to the continued attention to Venereal Disease both in the V.D. Clinic proper and in the hospitals of the Colony. The number of sera tested for the years 1929, 1930, 1931, and 1932 are respectively 1,741, 2,453, 4,266, 6,442.
During the course of the year the Kahn test was made the standard test of the Institute. A certain number of Wassermann tests are still carried out, however, at the instance of...
