42 ANNUAL MEETING. 



Furtlier progress has been made in the Geological room in 

 forming a collection of typical mineral ores from mining districts. 

 The sets so far arranged and tabulated are blue grounds and 

 matrices from the Kimberley Diamond Mines, presented by Dr. 

 Winn, London. A varied and interesting set of minerals from 

 the mines of East Germany, the Hartz, and Italy, by Major 

 Parkyn, F.G.S., one of the Honorary Secretaries. An extensive 

 collection of copper and other ores from the Bolivian Andes, by 

 Mr. Eobert Harvey, J. P., of Dundridge. Tin and copper ores 

 from Spain, by Mr. Eichard Pearce, F.G.S., H.B.M. Vice-Oonsul 

 at Denver, Colorado. A large and valuable set of minerals from 

 Rio Tinto Mines, Spain, and another from mines in Portugal, by 

 Mr. James Osborne, O.E., F.G.S., Truro. An interesting series 

 of specimens also, from the sett of the Uranium mines at 

 St. Stephens, by the Company, per Capt. W. E. Thomas, F.G.S. 

 The arrangement of mine minerals has been devised by the 

 Curator to meet the wishes of practical miners who desire to 

 see collective sets of ores from specific mining localities. The 

 minerals of the various districts are grouped irrespective of 

 kind, so that by the mixing together of country rocks and their 

 associated minerals, the miner may more easily recognize the 

 appearance of certain mineral ores he may meet with abroad. In 

 the Geological department an alteration has been made for the 

 better display of the fossils. The specimens are being mounted 

 on colored tablets and specifically labelled. The flat shelves on 

 which they rested in the upright cases have been taken out, and 

 inclined shelves substituted, with narrow strips of wood running 

 along in front to keep the tablets in place. The cases also have 

 been divided, so that the fossils in the collection will be placed 

 in proper geological sequence — a whole case being retained for 

 Cornish specimens. An excellent collection of Eocene fossils 

 from New Zealand has been presented by Mrs. A. P. Moor, 

 St Clements, and arranged in the one of the cases. 



A case has been set apart too in the Geological and Miner- 

 alogical room for the display of a set of Cornish Eocks, and to 

 this, in addition to the specimens the Institution already 

 possessed from various parts of the county, others beautifully 

 polished, have been contributed by Mr. Thomas Clark, Truro ; 

 whilst Mr. Howard Fox, F.G.S. , Falmouth, has presented types 

 of new kinds of rocks from the Lizard district,
