"Payne No. 5. In this experiment tool was used as shown in (fig) [drawing] consisting of iron legs, electrically insulated from each other, with grips to hold carbon upright to be put in circuit with resistance, so that current might be turned on gradually. In crucible, different chemicals containing neither oxygen nor carbon, were placed & brought by heat to a molten or liquid state, then the tool containing reg. Carbon plunged in & current turned on. The following results were obtained with the following chemicals:-- Chloride of Calcium. Melted at a very high temperature (red-heat) at which point it is a conductor of electricity. When current was turned on, a deposit was formed on each leg of the tool, on one side light gray on the other a shiny black. Chloride Aluminium:-- On application of heat gave of chlorine profusely & finally turned to a very fine gray powder, but would not melt at read-heat. Chloride Cadmium:-- Melted but on the carbon being plunged in it formed a thick coat all over it. Mercuric chloride. Would not melt gave up chlorine, turned yellow & finally disappeared Sulphur Monochloride:-- Conductor of electricity:-- Trichloride Antimony:-- Melted at low temp. but is conductor of electricity. Bromide Alumina:-- Would not melt gave up bromine & turned into fine gray powder Amorphous Phosphorous:-- Could not melt in air took five."
