EXAMINATION OF RATS FOR PLAGUE.
The examination is conducted at the Victoria Mortuary daily. Its results are embodied in Table II. It will be noted that the number found infected with plague was remarkably small.
BACTERIOLOGICAL EXAMINATION OF WATER SAMPLES.
The three sources of water supply of the Colony are Tytam, Pokfulam and Kowloon, and samples from each—both the filtered and unfiltered—are submitted to examination monthly. The collection of samples, which was undertaken in the past by the Public Works Officers, was carried out during the year by the staff of the Institute. The results of the examinations are given in Tables III, IV, & V.
