Sampling.
(32) The following list gives the amount of sampling done by the Sampler attached to the laboratory.
Table LVII.
1936. 1937.
Tin 3,862 tons. 4,315 tons.
Lard 132,002 cases. 140,436 cases.
Wood oil 30 tons. 60 tons.
Anise oil 10 cases. 10 drums.
Cassia oil 10 drums. 15 drums.
Firecrackers 3,289 cases. 4,076 cases.
Antimony regulus 5½ tons.
Teaseed oil 40 tons.
Water samples 1,921 samples. 1,702 samples.
Special Investigations.
(33) Again owing to shortage of staff very little fresh investigation could be initiated, as Mr. Tetley was transferred to the Import & Export Department soon after his return to the Colony.
(34) The London method for the assay of ingot tin has been adopted by the laboratory and proved to be as rapid as the old method.
(35) An investigation into the method of analysis of wolfram ore was carried out and certain modifications have been adopted.
(36) As a result of a complaint from Germany that a sample of local lard had been adulterated with vegetable oil a test used in Hamburg was investigated and it proved to be quite unreliable even when used on lards which were prepared in the laboratory from known genuine pigs fat.
