CO is passed over Fe₃O₄ at 275° and the C content determined periodically. Graphic treatment of the data gives values for dissolved C which, when subtracted from the totals, give values which become constant after 20 hr. This value corresponds to Fe₂C. Removal of C by H₂ gives the same values. The data of Fischer and Bahr (see abs. 973), similarly interpreted, give the same results.
