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.

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 asks a question about the paper of Yang and Mills (in: Phys. Rev. : 96 (1954), pp.191). Have their B-particles exactly zero rest mass or not?

Pauli thanks Salam for his "universal" paper.

Pauli talks about his positive reaction to Salam's paper.

Pauli talks about his trip to London. He makes more remarks on Salam's paper.

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).
