Pauli writes that there could be some possibilities of a position in the USA for Bhabha. He is publishing his Solvay report of 1939 in the Rev. Mod. Phys. Observations on Christy and Kusaka's calculations on the development of the shower and the pseudo scalar meson theory.

Pauli replies to Uhlenbeck's letter from 21 February 1941. He writes about beta-decay and meson-theory with zero spin for nuclear forces discussed by Oppenheimer. He writes about possibles subjects for his forthcomming talks in Ann Arbor.

The letter talks of progress in meson theory.

Pauli expresses his satisfaction about Jauch's theoretical work on electron scattering, but he doubts the experimental results. He writes about the latest results of cosmic ray research.

Pauli talks about the possibility to improve Serber's and Dancoff's method of the symmetrical-pseudoscalar theory.

Pauli writes about Christy's, Kusaka's and Schwinger's papers. He also writes about the world war.

Pauli writes about the world war and supports Uhlenbeck in these difficult times. He writes that he his invited to Lafayette's summer school.

Pauli congratulates on the birth of his Uhlenbeck's son. He writes about Bhabha's letter on the cascade theory. He writes about a paper by Dirac on quantum electrodynamics (published in: Proc. Roy. Soc.). He writes about the efforts of the authorities to get him back to Switzerland.

Pauli offers detailed comments on Jauch's calculations.

Pauli expresses great doubts as to the correctness of Dirac's quantum-electrodynamical approach. He explains that it is possible that the way to describe the interaction of particles with an electromagnetic field could be fundamentally wrong.
