Pauli thanks Einstein for the proofs of his paper (written by Einstein with Ehrenfest) concerning the elementary processes in which several quanta are simultaneously absorbed or emitted. Pauli shows that there exists an analogue for such processes in classical theory.

Pauli replies to Landé's question about a possible dicontinuity in the behavior of free and very loosely bound electrons.

Heisenberg asks for Pauli's opinion on his Zeeman effect paper.

Pauli asks about the possibility of visiting Copenhagen during his vacation. He says that he met Heisenberg in Copenhagen. He talks about his own work on heat conduction in solids.

Pauli gives a detailed account of his ideas about the anomalous Zeeman effect and the resulting consequences for the building of the electronic shell.

Pauli writes about the respective merits of the "inclination" theory and the relativistic theory of multiplets. He asks questions concerning certain transitions in alkali-spectra and the spectrum of Pb, anticipating Pauli's exclusion-principle.

About Hans Thirring's work on gravity, a work by Rella, Hans Thirring's article 'Atombau und Krystallsymmetrie'.

Pauli anounces his arrival in Tübingen on 9 Jan. 1925.
