A sketch of a statistical theory of a dust particle.

Fierz makes a detailed critical analysis of Weizsäcker's paper in "Die Naturwissenschaft". He rejects in particular Weizsäcker's suggestion of a modified logic for the explanation of the dualism wave-particle.

Fierz writes of his talk with Bohr about Weizsäcker's 'quantum-logic" and of Bohr's rejection of it.

Fierz makes some remarks about the $\beta$-decay and the properties of the neutrino and the anti-neutrino.

Fierz comments on two papers by Huang, Yangr and Luttinger on the statistics of rigid spheres.

Fierz writes about a note by Kusaka, published in: Physical review: 60 (1941) 61, regarding the theory of the neutrino with spin 3/2.

Fierz gives a differential equation and the canonical description of its solution.

Fierz writes about Pauli's jocular remarks concerning parity.
