Pauli says that he has not recently produced anything new in physics, partly because of many deaths in his environment in Zurich, including Placzek, Pauli's father, the wife of Carl G Jung and Hermann Weyl victim of a heart attack. He also speaks about his latest trip to Hamburg, where he saw Jordan, the astronomer Heckman and his former "chief" Lenz. Lenz will retire next spring, and there were some discussions about his succession. He talks to Bohr about the project of a Scandinavian Institute of Physics in Copenhagen. Pauli has also received another political letter from Bernadotte regarding the "Mainau statement" and asks Bohr for his opinion.

About Wolfgang and Franca Pauli's arrival in Copenhagen on the 9th of September 1937.

Pauli sends Bohr a short summary of his calculations on the H-atom using the "Göttinger" quantum mechanics. He writes about the difficulty of the excluded pendulum orbits (R=0), about the great progress made by Heisenberg on quantum mechanics and on Heisenberg's theory which may actually not not suffice to explain the two-term system of He. He also talks about other problems that are still open, like the time-dependent processes.

Pauli is glad about the changes Bohr made in his manuscript, in particular about his explanation of complementarity. He looks forward to meeting him in Hamburg.

Pauli asks if the last proofs of Bohr's paper are completed; if so, he would like to come to Copenhagen for some talks.

Pauli replies to a question from Bohr, whether an H-theorem can be derived from the point of view of quantum mechanics. He has made no progress in quantum electrodynamics and thinks that a completely new idea is still missing. He writes about Kronig's works and about Nature's introductory remark to Bohr's article.

Pauli urges Bohr again to publish his note on the magnetic electron. He criticizes his note on Beta-rays. Pauli plans to use a short visit to Copenhagen for writing a joint paper with Oppenheimer. He is not satisfied about his joint work with Heisenberg, because of the difficulties of the self-energy of electrons.

Bloch has given Pauli Bohr's letter and the note on the nuclear photo-effect to read. At Bohr's request, Pauli gives his opinion on it.

Pauli has just heard that the second proofs of Bohr's "Dialectica" article have been sent to Bohr. They have to be final and he asks him to return them promptly to the editor. In reading the proofs Pauli noticed a slight error in the German translation of the summary and asks Bohr to correct this. Bohr's article is now excellent. The next time he hopes to write to Bohr about physics again.

This is the last letter from the year 1948, written by Pauli just before going home for a New Year's dinner. Pauli is glad to report that he received the issue of "Dialectica" containing Bohr's article. Unfortunately he cannot say anything on the question of the reproduction rights. He has written to the editor again and hopes that Bohr will soon hear something. Pauli was very glad of the "hopeful spirit" of Bohr's letter. He is very interested in the publication of Bohr's old manuscripts, especially the paper with Rosenfeld on the charge measurements. He also thanks him for the copy of the "penetration" paper. He has had no time yet to look at it, because he was working on the new subtractive electrodynamics. He received a paper by Schwinger on self energy and polarisation of the vacuum. He is a master in concealing physical difficulties with mathematical elegance.
