| Description | He approaches Larmor with diffidence, requesting help with the mathematical papers of his brother, W J [William John] Johnston. He and his sister cannot distinguish between finished work and rough notes. There are few papers, since Johnston preferred to work in his head, then set down unfinished thoughts, before looking forward to work in retirement. His efforts on quaterions are described, with some studies about to appear in journals. He intended to combine the two papers now in press to produce a book 'for the propaganda of quaterions'. Johnston thinks that Larmor has seen most of the material before, as his notes are on some; but his advice is sought on how useful the papers are and how they might be dealt with. |
