Letter from J H [John Henry] Poynting, 10 Ampton Road, Edgbaston, Birmingham, to [Joseph] Larmor He is sending ['inflicting'] the note on the force of a moving sphere, the 'grandchild' of Larmor's own. Such a fundamental proposition should come out n a simple way and perahps Larmor will do it in a footnote. Poynting has been worrying at it and believes it is now correct and agrees with what he got in Philosophical Transactions volume 202. He intends to lecture to the Société Française de Physique in French, he and his wife travelling to Paris on 29 March. He asks if Larmor would like to come. 8 March 1910
