Laboratory.
The Bacteriological Laboratory was opened for work on 1st January, 1932. It undertakes
the examination of the routine bacteriological specimens from the District, the Municipal Hospital
and other local institutions. The total number of specimens showed a marked decline this year
owing to the decreased incidence of Diphtheria.
