Pauli writes about parity-violation. Includes an appendix about two-component theory.

Pauli makes remarks about a paper by Lüders on the TCP-theorem and about the formulation of the parity condition.

Pauli reports on Jost's results concerning the TCP-theorem.

Pauli replies to Lüders' comments on Pauli's last paper.

Pauli writes about a problem which has still to be solved: the application of the theory of invariants to the decay of My-mesons. He writes of his discussions with Heisenberg on a special case of the Lee-model.

Pauli writes more about the invariant weight factor in the commutation rules.

Pauli gives a preliminary answer to Pais' manuscript and letter. He makes some critical comments on Pais' treatment of Born's theory of the electromagnetic field. He makes corrections to his 1943 article on Dirac's theory of negative photons.

Pauli emphasizes the importance of Pais' result for the current density of zero-spin particles. But he expresses concern about the substraction formalism. He writes about his contribution to the Einstein-Festschrift.

Pauli writes about a long letter he has sent to Schwinger, Wentzel and Bethe on Vacuum polarization and photon self-energy. He would be interested in Pais, Oppenheimer and Dyson's opinion.

Pauli talkes about some calculations on classical diffraction theory in reference to Sommerfeld's work.
