Abstract
The specific heats of α‐ and γ‐manganese were measured in the temperature range 52° to 298°K. The specific heat curve of α‐manganese exhibited a small ``hump,'' extending over the temperature range 63°—103°K, with the peak of the ``hump'' occurring about 95°K. No anomaly appeared in the specific heat curve of γ‐manganese. The computed heat contents and entropies per gram‐atom are as follows: α‐manganese, H°298.16—H°0=1193±4 cal., and S°298.16=7.59±0.04 E.U.; γ‐manganese, H°298.16—H°0=1221±4 cal., and S°298.16=7.72±0.04 E.U.Keywords
