Pauli writes about his common work with Heisenberg and the difficulties involved. He talks about a paper by Bogoljubow on supraconductivity of which Wentzel thinks highly.

Pauli writes about the conference in Geneva, saying that the mirror-problem remains unsolved, and that it seems clear that the masses of elementary particles are certain eigenvalues. He is disappointed with the results of Heisenberg's school. He needs help in the mathematics of these eigenvalue problems and wants to hear Källén's opinion on several points. He hopes that Källén's generation will produce constructive models of elementary particles.

Pauli adds an extract from a letter by Weisskopf about the Geneva conference . He has a positive attitude to Schwinger's last paper. He talks about a spinor-model by Gürsey where the neutrino and not the vacuum creates strangeness.

Pauli writes about his dissociation from the Damm-Dancoff method. He writes about the mirror problem. He comments on publicity given to Heisenberg's work.

Pauli comments on Schafroth's preprint. He hopes that with Bogoljubow's and Wentzel's work one can arrive at a possible model for supraconductivity.
