Gustafson reports on work arising from his "addition in proof". He asks if C E Fröberg could visit Zürich.

Gustafson is sending Gunnar Källén to Pauli. He reports on Fröberg's scattering work and he is creating a post for Bradt.

Gustafson asks Pauli to give a statement on Källén's scientific qualifications for the Swedish authorities in order to get a professorship for Källén in Lund.

Gustafson sends a paper on mesons.

Gustafson writes on the congress in connection with the inauguration of the institute in Lund.

Gustafson discusses a possible solution of the Dirac equation using "analytical combination" and the work of student S B Nilsson.

Gustafson briefly describes Bertil Nilsson's work.

Hulthén comments on Jauch-Ning Hu's note published in: Physical Review: (May 1944), on nuclear quadrupole moment, on the implications of Amaldi's scattering results for theory of heavy-nuclei saturation, on his own publications and on the war situation in Holland.

Källén writes on his recent attempts to simplify the calculations on quantum electrodynamics.

Källén talks about calculation on an integral-representation of the S$_{c}$-function, avoiding the complex method of integration.
