Letter from Patrick Maynard Stuart Blackett, on a paper 'General classical theory of spinning particles in a Maxwell field' by Homi Jehangir Bhabha and H C Corben to Winchcraft Sectional committee: [Physics] The author refers to another paper as evidence for his conclusions. However, he has studied said paper and the claims are unjustified and 'quite untrustworthy'. He hopes the author will no longer use this data to inform his conclusions. He wishes his comments to be passed on to the author. [Published in Proceedings of the Royal Society A, 1941]. No received date given. 9 February 1941
