A considerable number of gratuitous determinations of minerals and rock samples have also been made by myself during the year; in fact, during the first part of the session hardly a week passed by without one or more such determinations, persons frequently calling at my private house for this purpose. I have hitherto not kept a list of the samples examined, and can, therefore, only mention from memory a few of the cases as under : Oriental ruby, brought by Mr. W. Goodlet from Eimu, West Coast, Middle Island. A collection of some thirty specimens of rocks and minerals from the Island of Borneo. Garnets, from the neighbourhood of Oamaru. Earthy vivianite (blue iron earth), from the Blue Spur mine near Lawrence. A number of samples of mica-schist and other rocks impregnated with pyrites, supposed to be silver-ore or gold. Ehodonite (bisilicate of manganese) from Nenthorn, &c. In conclusion, I may be permitted to mention that our mineral and rock collections have been materially increased by numerous presents during the year, the most important being as under:— Professor Black : A collection of some twenty specimens of the ores and other minerals of the mining district of Zeehan, Tasmania, including some valuable crystallized specimens of the rare mineral " chromite " (chromate of lead), also crystallized cerussite (carbonate of lead), sphalerite, siderite, &c. Mr. W. Goodlet: A fine specimen of the interesting ruby-bearing boulder from Eimu, Westland. Mr. A Hamilton : Fragments of moa bone, studded with small crystals of vivianite; also a number of specimens of the Port Chalmers volcanic breccia, showing inclusions of mica-schist, phonolite, nepheline, &c. Mr. L. Neil: A collection of some forty specimens of rocks from the neighbourhood of the Portobello gold-mine and other parts of the Peninsula. Mr. Thomas Esdaile : A number of interesting rock specimens from the neighbourhood of Oamaru. Mr. P. Marshall: Bock specimens from Lyttelton Harbour and Wanganui. Mr. F. B. Stephens : A collection of some thirty specimens of interesting rocks from Milford Sound. Mr. D. Wilkinson : A number of fine specimens of native copper, cerussite, mimetite, galena and other minerals from Broken Hill, New South Wales. Mr. Cochrane : Twelve specimens of auriferous quartz, from as many different mines in the Eeefton district; also rock specimens from Cape Foulwind and neighbourhood. Mr. J, Mouact: Several fine large pieces of stibnite from the antimony mine, Waipori. Most of the mineral specimens have been properly labelled and placed in the large glass cases for inspection by the students, whilst the rock-specimens are of great use in determinative petrography.
