TOXICOLOGICAL.
439
8. There was only one analysis in a suspected case of Opium poisoning. A careful search failed to reveal the presence of any poison.
9. On January 18th some rice said to have been poisoned, was forwarded for examination by the Captain Superintendent of Police, but no deleterious ingredient could be detected.
10. Two cases of mydriatic poisoning were recorded during the year. In both instances, abundant evidence was forthcoming, in the Laboratory, of the presence, in the material sent for analysis, of an alkaloid indistinguishable from the active principle of Datura.
WATER.
11. Thirteen samples of water were analyzed during the year. The majority of these were specially reported on to the Sanitary Board.
12. It would be difficult to find natural waters of greater inorganic or organic purity than the samples derived from Peak wells, and analyzed in this Department last Autumn.
MILK.
13. Thirty-four samples of Milk were analyzed during the year. In most cases the investigations were made with a view of ascertaining the extent of the variation between morning and evening samples of Milk from different sources. This enquiry will have to extend over a long period, and will require a considerable expenditure of time and labour. I propose to reserve the publication of the results of these analysis until the enquiry is completed.
GENERAL.
14. Eleven samples of Opium were examined in May, at the request of the Acting Police Magis- trate, with a view of ascertaining whether or not the specimens were prepared ones within the meaning of the Ordinance.
15. The remainder of the analysis were of minor importance only, and call for no special remarks.
I have the honour to be,
Sir,
Your most obedient Servant.
