7. Agglutination tests-Une thousand six hundred and forty sera were examined for the presence of agglutinins against various organismus.
8. Blood Clol Culture-Culture of the clot from agglutiua- tion specimens was carried out as a routine from January 15th, and the positive findings at the Institute, which included 47 Bact, typhosum, 3 Bact. paratyphosum A. 1 paratyphosun B, and 1 paratyphosum C, often threw an interesting light on the agglutina tion results. The para. C culture, kindly confirmed by the Salmonella Reference Laboratory in London, represents the first known case of para. O infection in Hong Kong since the war.
