Deals especially with applications to the theory of specific heats and to the photoelectric effect. Numerous references are quoted.

Among the papers on radiation are:
E. Bauer, Sur la théorie du rayonnement, Comptes Rendus, 153, p. 1466. Adheres to the quantum theory in the original form, namely, that emission and absorption both take place in a discontinuous manner.
