Heisenberg comments on his note on fluctuations which he wrote against the continuum-conception of Schrödinger. He talks about Dirac's ideas on relativistic formulation of Schrödinger's equation, and gives his thoughts on ferromagnetism and conductivity.

Heisenberg agrees with Pauli's calculations on the spinning electron in his last letter. He writes about Dirac's generalization of the transformation function S, and its physical content. He thinks that Dirac's work is a very great step forward. He writes also about Hund's work on H$\p2$, two calculations by Sugiura, on the number of dispersion electrons in Na, and on the continuous spectra of H.
Sans titreHeisenberg asks questions about the perturbation theory of the relativistic Schrödinger equation, about the mathematics of the electron spin and about spin and structure of the nuclei. He writes about his criticism of a paper by Ehrenfest on attraction and repulsion of spinning electrons, and about his own occupation with the logical foundation of the pq - qp formalism.
Sans titreBohr will pass through Hamburg together with Klein on their way to Holland. He hopes that Pauli will join him on his way back to Copenhagen.
Sans titrePauli announces his visit in Leiden and asks Ehrenfest to read his last paper on the H-theorem in order to discuss it with him.
Sans titreBohr has been thinking of writing to Pauli since the appearance of the Sommerfeld Festschrift, but the letter grew in bulk into a paper, which is not yet finished. Klein is working on relativity problems and is very hopeful about his work for: Z. Phys. : 53 (1928), pp.157".
Sans titreBohr thanks Pauli for his letter which gave him a welcome occasion for a small heart-outpouring. He has recently returned to his old primitive view on the problems of the electron theory after having been alarmed by Pauli's difficulty with the infinite self-energy of the electrons.
Sans titreBohr has sent a manuscript with the preparation of his discussion remarks from Brussels to Langevin. He is sending now another copy to Pauli and he would be very glad to hear his opinion before he gets the proofs. Bohr and Rosenfeld are eagerly awaiting the promised article with Weisskopf. He need not say how pleased he was to hear that there is a possibility of a visit by Pauli to Copenhagen in Spring. Perhaps Heisenberg and Dirac will come too. Bohr's own journey to Russia should take place in the beginning of May, and Margrethe and Rosenfeld will accompany him on the journey.
Sans titreMøller asks if he should find lodgings for Pauli?
Sans titreMøller replies to Pauli's letters and refers to Claude Bloch's paper about the introduction of a form factor in nonlocal field theories.
