Pauli adds some reference to Fierz's paper on magnetic poles in connection with group theoretical considerations, published in: Helvetica physica acta: 17, 1943.

Pauli gives some further remarks on the representation theory.

Pauli replies on a question about the energy-momentum tensor.

Pauli urges Thellung to finish his doctoral thesis.

Comments and calculations on a lemma by Stückelberg related to statistical mechanics.

The time has come for Pauli to go to India. He thinks that he could get leave from Zürich and should be in India from November 1952 until the end of February 1953. He asks if that suits Bhabha. He says theoretical physics is not making much progress. Källén is working on the question to look behind the veil of Dyson's power series. The new Swiss "infant prodigy", Alder, is working on angular correlation, shell model and related problems and Shafrot on superconductivity. He wonders about his lecture obligations in India.
