Bargmann proposes terminology for various types of tensors.

Bargmann has just received a letter from Pauli describing his latest work. The topic is not mentionned, but Bargmann agrees with the essentials.

The letter talks about the "sudden death of parity" in Wu's experiments, problems with nucleon-force data for deuterons and travel plans to Copenhagen, Zürich and Sydney.

All seven letters deal with Bohm's attempt to restore the deterministic picture by means of his hidden parameters, and with the connection between his ideas and de Broglie's conception.

Dyson writes about the renormailzed field theory and on Pauli's problem of "ghosts".

Einstein discusses the difference between his and Pauli's view on the significance of the psi-function. If this function does not supply a complete description of the state of a single system, one must look for such a complete description to which the real laws of nature must be related.

Gürsey gives a detailed view on the work he has done in the past month in elementary particles physics and announces a paper.
