Letter from [William Thomson, Lord] Kelvin, The University, Glasgow, to [Joseph] Larmor He should have thanked Larmor for his letter of 23 February long ago, and the copy of the paper he sent. The subject is interesting but he thinks it would not be possible to work out a theory to include 'Amperian currents, electrons, magnetic repulsions and attractions', in the way suggested. He hopes to talk about this if they can meet in London. 19 April 1895
