Letter from Geo Fras [George Francis] Fitzgerald, R E [Royal Engineering] College, Cooper's Hill, to [Joseph] Larmor He thanks Larmor for the return of his cape and returns a key he accidentally carried off. He has a proof of his 'Nature' review of Larmor's book, which he thinks is bad, and he is sorry he did not try to make intelligible the necessity for the electron treatment in order to get at the motion of matter. [Oliver] Heaviside's letter shows that he had not picked this up. Fitzgerald has not received the proof from the 'Electrican' yet, but thinks that this will be worse. He thinks that 'these unipolar dynamo things' will be old news, as [Erik] Edlund was working on such things thirty years ago. Fitzgerald describes Shooter's Hill as calm, with few distractions. 11 July1900
