Beeghly (15), in his review on the determination of nonmetallic constituents in metals, has discussed procedures for the anodic dissolution of the sample under conditions such that inclusions of metallic oxides, carbides, and sulfides may be recovered in their original form for further study and analysis. Bertetti (17) has described apparatus and procedures for the decomposition of insoluble metallic sulfides by reduction at a mercury cathode.…”
