Septic Tank Operation.-A very considerable amount of work was done with the experimental septic tank built at the Bacteriological Institute. For a period of about three months this tank was operated under conditions as nearly normal as possible, and analyses made of the water entering and sewage leaving the tank each day. The construction of the tank was modified in several respects as a result of the analytical work and a design for an improved tank worked out. Altogether 161 analyses of effluents, sewage and seawater were carried out.
The results showed that in its improved form the tank gave a degree of purification somewhat greater than that usually obtained in the English sewage works, the percentage purification, calculated from the amount of oxygen absorbed from permanganate being 81% as against 60% to 80% in the Home works.
Tin in Chinese Wolfram.-It has been found that some of the standard methods for determining the amount of tin in wolfram do not give accurate results when applied to certain Chinese wolframs. Dr. Lubatti has been testing the various methods of making this determination on a considerable number of specimens and has worked out a modified form of one process which yields very accurate results. This work is the subject of a paper which will shortly be published in the Journal of the Society of Chemical Industry.
New Territory Waters.-An investigation is in progress into the purity and constituents of the waters from the police stations and village wells of the New Territory. Twenty samples from all parts of the Territory have been obtained through the courtesy of the Police Department and subjected to complete analysis, the mineral constituents present being specially determined.
The results have shown that not only are the police stations supplies excellent but that the water from the village wells is in most cases surprisingly good. Not only is the water good for potable purposes but owing to its softness and low mineral content, is very suitable for manufacturing and industrial uses, should it ever be required for such purposes. It is proposed to examine in all from 60 to 80 samples.
Morphine Poisoning.-A certain amount of work has been done on the reduction of dioxymorphine to morphine by processes suitable for use in toxicological cases.
