Dr. Wahl presented for inspection a specimen of aluminium, manufactured at present on the commercial scale by the Pittsburgh Reduction Company. The process employed is that of----Hall, of Oberlin, O., which consists substantially in dissolving alumina by igneous fusion in a bath of metallic fluorides, and electrolyzing the resulting solution, by which, it is affirmed, the alumina is decomposed while the solvent remains unaffected. Dr. Wahl spoke in general terms of certain technical applications of aluminium, especially to the increasing use of ferro-aluminium by foundrymen to improve inferior irons. He also exhibited several medallions struck from aluminium, made by the Aluminium Company, limited, at the works at Oldbury, near Birmingham, England. They had been presented by Mr. H. Y. Castner, whose process is there in operation.
