Contributions to the Data on Theoretical Metallurgy: [Part] 5. Heats of Fusion of Inorganic Substances
From Introduction: "Examples of the use of the derived heat-of-fusion values in the application of thermodynamics to problems concerning metallurgical practice are not given here, but the reader is referred to the textbook of Lewis and Randall (454), in which the methods and types of calculations are adequately portrayed, and to the papers of Maier (469, 470, 471), in which the application of thermodynamic methods to various problems of metallurgical interest has been illustrated and discussed."

Contributions to the Data on Theoretical Metallurgy: [Part] 6. A Revision of the Entropies of Inorganic Substances--1935
From Introduction: "Moreover, a critical study of the existing vapor-pressure data made by the author (98) furnishes entropy of vaporization results suitable for obtaining approximate values of the entropies of a number of gases from the entropies of the solids or liquids. Consequently, it appears worth while at the present time to supplement the former publication, giving the new values now obtainable and making such revision in the older values as the data warrant."
