II. On certain ternary alloys. Part III. Alloys of bismuth, zinc, and tin, and of bismuth, zinc, and silver

Abstract

The general methods adopted in carrying oat the experiments detailed below were identical with those described in Part II, the weighed metals being fused together under cyanide of potassium, well intermixed by continued vigorous stirring, and poured into red-hot narrow clay test-tubes, which were then inserted inside thin iron protecting tubes, closed at the lower end, and immersed in a bath of molten lead, maintained at as nearly as possible a constant temperature by means of a series of Bunsen flames playing into the inter-space between the cylindrical iron vessel containing the lead and an outer concentric clay jacket.
