Letter from W. Pauli to Teubner Verlagsgesellschaft linked to the publication of "The theory of relativity".

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

Pauli thanks Wightman and Michel for the study of his paper. He remarks on a priority question regarding Schwinger's paper of 1951. He writes about properties of isotopic spin spaces. He writes about "Schwinger's school" and "Wigner's school".

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

Pauli makes more remarks about Schwinger's theory.

Pauli replies to Weisskopf's letter. He asks why the cut-off radii of the proton and the neutron are exactly equal. He makes remarks on the quantum theory of fields, and Landau's contribution to this problem. He writes about Schindewolf's book on evolution recommended to him by Weisskopf.

Pauli asks if Walden has more information on his claim that Mendeleev discovered the periodic table through dreams.
