(i) Vader this heading are included the routine examinations of the reservoirs and filter beds of the Colony water supply, daily samples from supply taps in various parts of the Colony, and samples from waterboats supplying shipping in the harbour.
(ii) Food samples consisted principally of milk, for control of pasteurisation, but cases were found of butter substitutes being sold as butter, and arachis oil being sold as olive oil.

At the Commission of Enquiry which was set up both the Government Chemist and Mr. Terry gave evidence.
The same material is believed to have caused another fire in a godown in the Colony.
A dangerous commodity which was discovered during these investigations was crude caustic soda containing a large quantity of metallic sodiumu, sufficient to cause ignition when the material was plared in water,
