Rzewuski encloses a note concerning conservation laws for non-local field theories.

Møller and Kristensen send notes from a colloquium on nonlocal theories. They relay as invitation from Bohr to visit Copenhagen for the CERN Study Group.

Møller and Kristensen reply to Pauli's letter and manuscript. They writes about details of the mathematical development of their theory, with special reference to the work of Claude Bloch.

Fierz investigates whether the non-statistical H-curve has the properties demanded by Boltzmann.

Fierz sends a note written by Schiff. He solves a differential field equation.

Jordan writes about a forthcoming talk by Pauli in Hamburg.
