Where potassium permanganate is administered in cases of morphine poisoning, the greater part of the morphine taken is converted into dioxymorphine, which does not give the reactions of morphine. The object of the investigation is to find a suitable process for re-constituting the morphine so that it may be separated and recognised by the usual methods.

Wood Oil.-An attempt was made by Mr. Lane to reach a definitive test for pure wood oil. The Insoluble Bromide Value was found useless for the purpose and work on the Titer Test is still proceeding. The influence of oxidation on the fatty acids during separation has to be solved.

Camphor.-The Specific Rotation in alcohol has been tested and found valueless as an exact measure of the Camphor content.

A new method has been worked out by Mr. Lane for the estimation of small quantities of camphor oil in camphor by the iodine value and found of use as a confirmatory method.

12. STAFF.

Mr. I Cheng resigned on the 9th August last and Mr. Tam Yam-yeuk joined the staff as temporary Assistant on the 1st September, 1921.
