3. Filaria-Microfilarial parasites were found in three
cases.
4. Anthrax-Infection with B. anthracis was established in thirty-seven instances in blood filme taken from sick animale.
6. Faeces-Twelve thousand eight hundred and twelve stool specimens were examined for parasites, ova or cytological picture. Fgures for E. histolytica are more than double those recorded last year. An idea of the incidence of helminth in- festation among the general population may be gained from the fact that so far it has not been possible to take any specimen from a large tank containing the community's nightsoil without finding Ascaris, Clonorchis, Ankylostoma and Trichuris ova present. Some, but not all, specimens also contained Fascio- lopsis ova.

(4) Serology.
The Kahn reaction-Forty thousand seven hundred and thirty-five sera were tested. This figure represents roughly the maximum number that the existing racks and apparatus can deal with, and in order to ease matters the introduction of an exclusion test, such as the Berger-Kahn, for routine antenatal and cord sera is under consideration.

(3) Haematology.
The majority of this work is carried out at the Queen Mary laboratory and the Kowloon branch, as the summary shows.
7.
Agglutination tests-One thousand Ave hundred and forty-two sera were examined for the presence of agglutinins against various organisms. During the last six months of the year a paratyphoid C suspension was included in all tests for enteric agglutinins. Positive findings for Br. melitensis and Br. abortus relate to a head of cattle in Fatshan and one local
COW.
8. Blood Clot Culture-Bact. typhosum was isolated from the widal clot in 109 instances at the Institute and 6 cases gave a growth of Bact. paratyphosum A.
