        Temperature-temperature-difference curves for exceptionally pure electrolytic Fe were recorded photographically.  Both the heating and the cooling curves show sharp breaks at the magnetic transformation point as well as more pronounced ones at the β-γ transformation.  Wever has questioned the idea advanced by Ruer and Bode that the magnetic transformation in Pure Fe at 769 is a homogeneous phase change (abs. 2919).  The evidence, both experimental and theoretical, bearing on this point is reviewed.
