          Relation between the thermomagnetic and catalytic properties of Fe, Ni and Co catalysts for Fischer hydrocarbon synthesis (CO+2 H₂) was studied (a) for a variety of conditions of catalyst preparations and (b) with several catalyst promoters.  In general, good catalysts exhibited a distinct type of thermomagnetic curve.  However, this relation should not be unduly emphasized until more is known about other properties that are responsible for catalysis.
