Pauli writes about the necessity for continuation of his leave from Zürich. He writes about the possibilities for non-American physicists to get jobs in the U.S.A., because many Americans are busy with defense work. He writes about his paper with Dancoff on strong coupling in the pseudo-scalar meson theory and about his correspondance with Dirac on his efforts to remove divergences in quantum electrodynamics. He comments on Scherrer's attitude to theoretical physics.
