Letter from Geo Fras [George Francis] Fitzgerald, St Lawrence Lodge, Sutton, to [Joseph] Larmor Fitzgerald gives two reasons why he thinks Larmor's method of making a radial torsional field makes a discrete one. He cannot see much difficulty about forces sufficient to make atoms with ionic charges 'move as fast as comet's tails'. A force four or five times greater than gravity would do it and a very feeble electric force acting on the ionic charge would be equal to it. He would have surmised that ionic doublets were matter, but this is pure speculation. He is surprised that Larmor's doublet radiates so little, giving his reasons. 6 July 1894
