THE DARK FERMENTATION ROOM (formerly the Governor's Banqueting Hall).
This view was taken a few days before H. E. the Viceroy inspected the Laboratory on 8th November, 1899.
The room then contained 1,238 flasks, containing 2,058 litres of fermenting bouillon, weighing 2 tons, 1 cwt., or about 411,600 adult doses of vaccine. The flasks are
kept in this room for 6 weeks or 2 months, to permit fermentation; being shaken every two days. They are then tested for purity, sterilised, and decanted (v. pl. 9).
