Pauli writes about his decision to remain in Zurich. For the USA he forsees, in about five years, the danger of increasing interference by the military authorities in physical research. As regards Einstein's field equations, he does not believe that the classical field thery can yield any new results. One has to wait for a new generation of young physicists. He also writes of Bertrand Russel's lectures in Zurich.

Pauli thanks Einstein for his manuscript "Quantum mechanics and reality" printed in Dialectica. He explains the difference between his own attitude to physics and Einstein's. Pauli believes that the description of reality as it is given by quantum mecahnics is complete.

Pauli congratulates Einstein on his 70th birthday. He remembers gratefully Einstein's address in Princeton 1945 after Pauli received the Nobel Prize. He also writes of his forthcoming contribution to the Einstein volume in the Living Philosophers".

Pauli would welcome a new assistant. He makes some remarks on breit, Bloch and his physics.

Pauli refers briefly in this postcard to a paper written by Fock (in: Z. Phys. : 57 (1929),pp.261), to the "Fernparallelismus" of Einstein in which he does not believe, to a relation made by Fürth connecting radii and masses of electron and proton with c and h.

Pauli announces his visit in Leiden and asks Ehrenfest to read his last paper on the H-theorem in order to discuss it with him.

Pauli reports on Lise Meitner's criticism of the Ellis-Wooster measurement of beta spectrum.

Pauli gives some personal evaluations of Oppenheimer and Bloch. He also comments on Rutgers and his progress with quantum electrodynamics.

Pauli discusses the question of the width of the zero-order spectrum of a refracted electron beam. He suggests that Kramers should calculate it for gases or liquids.

Pauli thanks Eddington for his book on relativity he has sent to him. He explains the reasons for his opinion that Eddington's attempt of a formal unification of electromagnetic and gravitational field have no physical significance.
