Be fore the blowpipe on charcoal, in the inner flame, emits arsen ical fumes and melts into a black magnetic globule. Partially soluble in nitric acid, leaving a residue of arsenious acid. IP As 1 . Fe 4 As 3 gives iron 33 - 26, arsenic 66 - 74. Analyses of lolingite from Keichenstein a by Karsten, I by E.
