Pauli writes about Heisenberg's paper in: Z. Naturforsch.

Pauli gives details of his discussion with Dyson about his definition of renormalization through power-series.

Pauli writes about Touschek's papers. He writes about the conservation of lepton-charge.

Pauli writes about the Majorana-Fierz condition of reality and its consequences for the expression of the neutrino-pseudo-current.

Pauli replies to Touschek's letter of 11 November 1957 about strong interactions between hyperons, K-mesons and nucleons. He asks Touschek about conservation of the isotopic spin component T3 in medium strong interactions.

Pauli replies to Touschek's letter of the 18th November 1957. He writes about P and T violation.

Pauli writes about the possibility of parity's conservation in the Beta-decay of the My-meson. He writes about the conservation of lepton charge as an independent physical principle. He comments on a preprint by Gorter on positron-decay.

Pauli asks which of Touschek's papers he could read. He writes about Leiden's paper on Gorter's experiments with orientated 58 co-nuclear spins which are in good agreement with the two-component theory.

Pauli asks Touschek about his attempt to combine the conservation of barytons and leptons. He writes about his talk with Salam in London.

Pauli writes about his interest in Touschek's remark at Padova and Venice about the derivation of C- and P-symmetry from special properties.
