The letter talks about some results of the application of "substraction-quantumelectrodynamics" to a higher approximation of the Compton-effect.

Pauli advises van Hove to treat his nucleon problem in a strictly relativistic way. This will change considerably the results concerning the magnetic moment of nucleons.

Pauli replies to a letter about affine field theory. Pauli explains why the unity of field theory is impossible, because the reduced curvature tensor splits into a symmetrical and antisymmetrical part, which can never be brought together again.

Pauli asks Fierz some personal questions regarding the chairs for theoretical physics in Zürich and Basel.

Pauli makes some comments on a paper sent by Dyson.

Pauli comments on a letter to Schwinger. He accepts his results, but rejects some of his proofs and arguments.

Pauli recommends his assistant Jost to Bethe. He gives a critical comments on a paper by Dyson about regularization.

Pauli thanks Kronig and his wife for their hospitality.
