Comments on Bhabha's writings on wave equations for particles with higher spin. Bhabha asked Pauli to send his corrections to the editorial office of the Rev. Mod. Phys for printing.

Pauli discusses his trip to India.

Pauli gives his opinion on Bhabha's presentation in Zürich about meson and proton dispersion. He also reports about his correspondence with Heisenberg on the same subject.

Pauli has been in Princeton since the 24th February and he is making some inquiries on Bhabha's plans. He says that in Princeton the meson theory with particles in 1/2 speed is in vogue. He heard some contradictory news on Bohr.

Pauli hopes to be able to read Bhabha's cascade theory in Proceedings from the Indian Academy. He expresses his agreement with some of Bhabha's statement, but disagrees with his criticism of Christy and Kusaka. He makes general remarks on the relation between Bhabha's classical theory of 1941 and the Pauli and Dancoff theory. He has read with a great interest Dirac's new work (Proc. Roy. Soc. March 1942). He speaks about the two letters he has exchanged with him.

Errors in a work of Wilson, on which Chakrabarty's research is founded invalidate Chakrabarty's conclusions. Pauli has returned to work at Princeton from his summer estate and asks Bhabha to write to him often as he is becoming isolated.

Pauli received an invitation to India from Dr. S S Nehru and he is asking Bhabha for more details. He thinks his visit would be possible in 1949. He says that Dr. Villars has made a theory on the magnetic moments of H3 and Jost has extended the theory of the emission of many low frequency photons.

Pauli says that he thanked Nehru for his invitation, but declined because he plans a visit to Sweden and Copenhagen in September. He told Nehru that he has accepted Bhabha's invitation.

Pauli is waiting for news concerning Bhabha's possible arrival during this semester. General questions concerning Pauli's trip to India.

Pauli is back from his trip to India. He has written a paper on the Hamiltonian structure of non-local field theories.
