Pauli writes on physics and psyche, on a conversation with Jung on Albertus Magnus and Regiomontanus and the latter's interest in magic. He explains Jung's reaction to the fact that Cicero translated "atom" by "individuum".

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

Pauli talks about questions in connection with the preparation of a lecture on problems of quantum electrodynamics: 1) about Lee's non-relativistic models for renormalization, 2) about longitudinal photons, 3) about a paper by Green published in: Physical Review 95, 548 - 1954.

Pauli thanks Källén for his reply. He objects to his views on the gauge-invariance. He writes on the danger for a theoretical physicist to stick to one special formalism. This is also Källén's mistake in his formulation of the Lee-model.

Pauli talks about the Schafroth's new paper. He explains why his model gives quantitatively not correct results and how this can be mended. He comments on the papers by Butler and Friedmann. He talks about CERN and about his paper for the

Pauli writes about his contribution to the Bohr Festschrift. He writes about strong and weak reflection, particle and anti-particle conjugation and about biological evolution. He criticises Schwinger's work.

Pauli makes a short reference to Jauch's work.

Pauli compares the roots of his metaphysical beliefs with those of Fierz. He also writes on the Jewish component in modern science.
