Experimental working-tests of parcels of ore from 1 to 3 tons in weight are undertaken by the following processes : — (1.) By Gassel Cyanide Process : Wet- or dry-crushing.— a, by percolation ; b, by agitation. (2.) By amalgamated copper-plates. (3.) By amalgamation in pans; Wet- or dry-crushing— a, by raw amalgamation in charges ; b, by Washoe process with chemicals. (Hot pan-amalga-mation, after chloridising roasting.) (4.) Chlorination : Small barrel tests. Metallurgical students are permitted, on the approval of the director, to work in the experimental plane during the treatment of ores so as to enable them to acquire a knowledge of the practical working of the different processes. Goveening Body. At the annual meeting in February, the following were elected for the year 1895 : President, Mr. James McGowan, M.H.E.; Vice-president, Mr. T. A. Dunlop ; Treasurer, Mr. J. Hague-Smith ; Council, Messrs. W. Baker, P. C. Hansen, E. F. Adams, W. Burch, and L. Melhose. During the last year, twenty-eight different parcels of ore, having an aggregate weight of about 22 tons, were treated at the experimental plant attached to the school. Of these, twenty-five lots, or 19 tons, were treated by the cyanide process, and three parcels, or 3f tons, by panamalgamation. Some of the experiments made in the treatment of these ores are very interesting. Certain of the parcels of ore from the Monowai Mine were treated very successfully. From No. 1 parcel 92 per cent, of the assay-value of the gold was obtained, and 58 per cent of the silver; from No. 2 parcel, 91 per cent of the gold and 77 per cent, of the silver; but from No. 3 and No. 4 parcels 77 per cent, and 70 per cent, of the gold respectively was obtained, while only 13 per cent, of the silver was extracted, the cyanide seemingly having a greater affinity for the copper pyrites than the silver which was in the ore; and the whole of the bullion was found in the first three zinc-boxes from the top, while the greatest amount of copper was deposited in the lower boxes, thereby indicating that the action of the zinc exerts a selective influence, first on gold, next on silver, and
