(3) Urine.—Culture of urine for pathogenic microorganisms was performed on 67 specimens, in the great majority of cases the B. coli was the suspected organism. In every case a routine examination of the specimen, chemical and microscopic was always carried out as well.
(4) Urethral and cervical smears.—Smears from the male and female urethra or cervix were examined for the presence of the Gonococcus in 300 cases,
(5) Nasal Scrapings.—Stained smears were made of nasal scrapings in 73 cases for the presence of B. leprae. Most of these specimens were forwarded by the medical officers in charge of prisons in Victoria and Kowloon.
(6) Throat Swabs.—The number of examinations carried out under this heading for the year shows a great increase over previous years owing to the epidemic of diphtheria which visited the Colony in December. This necessitated an extensive search for carriers among the dairies quite apart from the routine examination of contacts, convalescents and patients.

In every case a test for increased globulin was made and a stained smear made of the centrifugalized deposit for the type of reacting cell.
(8) Pus and miscellaneous material.—Twenty-five specimens of pus were cultured for pathogenic organisms. The results call for no comment. Twelve dog's brains were examined for Negri bodies and one positive result recorded.
(9) Plague infected material. The results under this heading are discussed in connection with Anti-plague work elsewhere in this Report.
