The work begun in 1930 by Mr. V. C. Branson on the modified Bolton & Williams heat test for China wood oil was continued with valuable results. The small number of samples examined this year has prevented the collection of sufficient data to establish the method as a commercial test.
A full examination has been carried out of the composition of the coal tar from the local gas works, to ascertain its commercial value.
The work on ascitic fluids has been continued in conjunction with Prof. Gerrard of the Hongkong University. Fifty-one samples have now been examined.
Work was carried out in conjunction with the Army Veterinary Officers into the calcium content of the blood of army horses and mules.
Investigations have been made into the analysis of Chinese soy, the determination of the viscosity of bird-lime for the Sanitary Department and the gumming of certain types of Naval lubricating oils.

A series of tests has been made on behalf of the Naval Authorities to ascertain the keeping qualities, under tropical conditions of the absorption charges used in the Davis Submarine Escape Apparatus, and this work is being carried out monthly,
