Pauli fixes a convenient time for Kronig's visit to Zürich. He writes about a lecture he will give in Turin.

Pauli and Scherrer invite Kronig to a conference in Zürich on X-ray physics.

Pauli hopes that Kronig and Kramers will come to the conference.

Pauli asks for clarification of beta-decay Hamiltonian.

Pauli plans a reconsideration of the Pauli-Fierz work (in: Z. Phys. : 106 (1937), pp.572) on the H-theorem.

Pauli has just received J. Leite Lopes' paper "On the particle picture of quantized Bose Fields I", and mentions two relevant papers by Dirac, which Lopes did not quote.

Pauli replies to Lüders' letter of 30 June. He makes remarks about anticommutation of different spinor fields.

Pauli acknowledges Lüders' comments on his Bohrfestschrift article. He writes of his study of Lee's paper (in: Phys. Rev. : 95 (1954), pp.1329) and of some improvements he could make on it.
