18. A diminution in the number of these samples took place during the year. The investigation of the nature of various stones removed from the human bladder by the Professor of Surgery to the University, has been continued by the complete analysis of a further 22 samples.
Materials from Government for Testing.
19. There has been a slight increase in the number of samples of materials submitted by Government Departments for testing. It is to be regretted that some departments do not make more use of this Laboratory to ensure that Government receives genuine materials. Last year four paint samples were submitted—of which only one was genuine—yet this year only a further four samples were submitted. In this connection, a case occurred during the year in which inferior paints were put up in old tins of a reputable proprietary brand. On analyses done by this Laboratory the vendors were successfully prosecuted by the local agents for the brand in question.
20. An example of the value of this Laboratory in this respect is shown by the examination of ghee samples for the Police Department. In the spring complaints were made that the ghee supplied to the Indian Police officers was not of first grade quality as demanded by the contract. Samples were submitted here and the figures showed that the ghee was either adulterated or of very poor quality. The cancellation of the contract was under consideration. A standard for first quality ghee, based on the Indian standards, was fixed by this Dept. Samples of the ghee issued now are analysed about every ten days. It is to be reported as a result that the ghee now supplied is consistently of good quality.
21. More fumigation work with Hydrocyanic Acid gas has been carried out on books and documents for the Law Courts and Colonial Secretary's Office. The fumigations appear to be successful in keeping down the attacks of insects on books and are much quicker, more efficient and cheaper to carry out than varnishing with a protective paint.
22. During the year every consignment of coal for the Harbour Department and the P.W.D. were sampled and tested in order to arrive at the price to be paid to the contractor.
Semi-official Work.
23. The tanks of 43 ships were tested for inflammable vapour with the Clowes Redwood apparatus. The majority of the other work under this head was for the Naval & Military Authorities. The investigation in connection with corrosion of Recuperator and Buffer systems of guns was carried on during the year.
