Letter from Geo Fras [George Francis] Fitzgerald, Trinity College, Dublin, to [Joseph] Larmor He thinks Larnor may be right, but Fitzgerald gives a case where the force was a function of vibration. With Larmor's atoms built of rotating electrons, rotating at a fixed rate, this is the force to be expected. With some rough notes by Larmor verso, headed 'Salary'. 3 February 1895
