Letter from J [Joseph] Larmor, St John's College, Cambridge, to [John Henry] Poynting He put some 'hasty nonsense' about a cord at the end of his letter from yesterday, and he gives the equations as they should have been. He concludes his amended description by saying 'This is what you denied for radiation: but I see no way out of it here'. With a pencil note: 'c.f. J.H.P. Phil Trans 1903', presumably referring to Poynting's paper 'Radiation in the solar system: its effect on temperature and its pressure on small bodies'. 1 November 1903
