Pauli talks about the conference in Rochester. He waits for the outcome of some new experiments on parity. He talks about his doubts about the two-component theory. He talks about his paper "on the conservation of the lepton-charge".

Pauli asks questions about the non-occurence of $\pi \to e+v$ and $\pi e+v+photon$. He talks about Heisenberg's work and his idea that the real world results from a bi-section of a $\gamma$-invariant world, for non-zero rest mass and for the neutrino a leptonic charge.

Pauli asks questions about the reactions $\pi \to \mu + \nu$ and $\pi e + \nu$. He comments papers by Sakurai and Havana (in: Progr. Theor. Phys. : 17 (1957), pp.592).

Pauli writes of his reactions to the experiments showing parity violation. He gives reasons for his doubt of this possibility up to now. The main problem is now: why are the strong interactions reflexion-invariant? Pauli makes some general considerations on TCP-invariance.

Pauli makes technical arrangements in connection with his impending visit to London. He criticises the title of Salam's paper "Universal Fermi-interaction". He says that theoreticians should never use the word "universal".

Pauli encloses a note on the magnetic moment of the triton, which can be explained by exchange momenta given by the meson theory.

Pauli writes about the magnetic moment of $H_{3}$. He is working on the theory of it with Villars.

Pauli replies to Rzewuski's letter and manuscript. He quotes from his correspondence with Møller and Kristensen. They believe that the difficulties with certain form factors (described by Claude Bloch) are that they always lead to a-causalities.

About the philosophical signification of Quantum Mechanics. Remarks on a manuscript by H. Reichenbach, among others concerning the definition of 'Normalsystem'.

Pauli makes historical remarks on Fermi's beta-decay theory and on the neutron. Pauli talks about his paper on paramagnetism (in: Z. Phys. : 41 (1927), pp.81) and about Dirac's statistics (Proc. R. Soc. Lond., A : 112 (1926), pp.661).
