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 comments on a letter to Schwinger. He accepts his results, but rejects some of his proofs and arguments.

Pauli recommends his assistant Jost to Bethe. He gives a critical comments on a paper by Dyson about regularization.

Pauli refers to questions regarding the equivalence of pseudovector coupling.

Pauli thanks Weyl for his book on the philosophy of mathematics and natural science. He makes two critical remarks: 1) It is not correct to connect Leibniz with the principle of exclusion. 2) There is no asymmetry of the past-future relation in spontaneous radiation processes, but the concept of spontaneity needs a better definition.

Pauli thanks for Yank's and Feldman's paper. He writes about Glauber's calculations.

One of three letter written by Pauli to the "Comité Louis de Broglie" which contain technical details concerning Pauli's contribution to the anniversary volume for Louis de Broglie.

The trip to India is planed for November. Pauli proposes to talk about field quantization and to hold a seminar on open problems in theoretical physics. Pauli hopes to see a presentation by Salam on his work on meson theory. Pauli invites Bhabha for a visit to Zürich during his Europe trip.

Pauli thanks de Broglie for sending him his paper "La physique quantique restera-t-elle indéterministe ?" Pauli makes some critical comments on it.
