Notes on Spin 0 Meson in electromagnetic field.

Meitner recalls Pauli's neutrino proposal.

Matthews writes about his calculations on the combined interaction of spin-zero mesons, nucleons and electromagnetic field.

Lüders agrees with Pauli about the necessity of including Schwinger's name in the co-authorship of their invariance theorem. He talks about his work with Zumino on TCP-invariance.
