        Cementite was electrolytically isolated from a steel containing 1.58% C and pressed into the form of a cylindrical rod.  The density ρ was 4.35.  The intensity of magnetization was measured in the field of a Du Bois electromagnet.  The magnetization reached saturation in a field of over 10,000 gausses, the value found being σ=I/ρ=135 C. G. S. units.  Measurements also were made on white cast Fe containing 3.75% C.  From the known proportion of ferrite and cementite and from the measured saturation value of the specimen, the saturation value of cementite was calculated to be I=955 or σ=I/ρ=135, which is the same value as was found directly.  The same measurements were made for the double carbides of Fe and W and Fe and Cr and for a number of different steels; the results are given graphically.
