Touschek writes about Pais paper published in Physica. He writes about his own work on time-reversal.

Touschek gives arguments for conservation of heavy particles based on Eich-invariance.

Touschek comments a part of Pauli's lecture in Varenna, which is superscribed "The nucleon magnetic moment in the static theory".

Thirring replies to Pauli's question in his last letter. He says that the answer is in Michel's paper published in: Nuovo Cimento: 10(1953), pp.334.

Thirring makes calculations on Raman's scattering for certain conditions in Lee's model.

Thirring agrees with Pauli's formula obtained from the Thirring model. He discusses Pauli's remarks on mass renormalization in this model.

Thirring presents his model for a renormalized quantum theory along with difficulties applying it to nuclear problems. He discusses the work of Petermann, Edwards and Keberle. He writes about his travel plans to Italy and Yugoslavia.
