Pauli writes of his visit to California and of the calculations he made there. He suggests that Fierz could write a second part of his paper on the scattering of charged mesons.

Pauli has just finished an article with Dancoff on meson theory and he sends its contents. He gives some comments on the war's consequences on physic.

Pauli expresses his enthusiasm over Dirac's Bakerian lecture and makes several comments on it.

Pauli writes about the magnetic moment with strong coupling in the meson theory. He comments on the two-nucleon problem.

Pauli replies to Wentzel's letter of the 2nd October 1942. He comments on Wentzel's calculations.

It has been a long time since Pauli received a letter from Bhabha and he repeats the contents of his last letter.He reports on various works of Jauch (calculation of proton and neutron's magnetic moments) and of Pauli himself (on field quantizing after Dirac's new method and on his new theory on strong interconnection).

Pauli discusses a work by Wilson on the influence of damping on the brems-radiation of mesons with spin 1.

Pauli discusses Schwinger's modification, published in: Physical review: (1942), 61, 387, of the Rosenfeld-Moller meson exchange theory. He obtains equations for deuteron ground state and discusses the attempts to solve them, with applications to scattering and work in
