Letter from H W [Henry William] Watson, the Rectory, Berkeswell, Coventry, to [Joseph] Larmor He apologises for raising a matter similar to his previous letters of some months ago. He refers to Larmor's 1884 paper and an interestign interpretation occurring in the formulae for E.M.F. [electro-magnetic force] in space. He cannot see on what grounds Larmor states that the velocity is absolute. In any laboratrory with magnets or a current with circuits 'you have a moving conductor - say a revolving sphere'. The E.M.F. calculated element by element differs from that if the sphere was reduced to rest. 27 September 1888 [?]
