Pauli reports on attempted mathematical transformations by Salam and Nishijima.

W. Pauli thanks for the received book 'The Tower and the Abyss' and makes remarks, taken from Bailey's 'The Greek Atomists and Epicure', about the concept of 'Individual'.

Pauli replies to Schafroth's letter. He comments on supraconductivity. He writes about vacancies for theoretical physicists in Switzerland and about difficulties of burocracy. He talks about parity and conservation laws for light particles.

Pauli acknowledges receipt of Heisenberg's manuscript. He discusses some mathematical difficulties in the light of a paper by Wightman (Phs. Rev. 101, 860, 1956).

Pauli makes further remarks about the formulation of certain results in Heisenberg's manuscript.

Pauli continues his comments on Heisenberg's manuscript, especially on terminology.
