Pauli writes from Princeton to Jauch in Zürich about Jauch's calculations on electron scattering. He asks questions about life in the Institute.

The letter contains a short remark on self-energy and a longer one meson-theory, with reference to papers by Schwinger and Oppenheimer.

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.
