| Description | He has returned the paper ['A new current weigher and a determination of the electromotive force of the normal Weston cadmium cell'] by [William Edwrad] Ayrton, [Thomas] Mather and [Frank Edward] Smith, with his report to the Royal Society. He mentions a few 'trifling things' that he thought not worth mentioning in the report, including corrections to equations, but 'the whole seems an exceedingly good piece of work'. One formula is suggested to be peculiar to a helix, but Gray thinks this is not so, giving his reasoning. He extends his discussion to a Royal Society paper by V. [John Viriamu] Jones, and a similar point to Gray's made by Lord Rayleigh. He concludes by describing the fine weather and inviting Larmor to stay at the house of the headmaster of Madras College, arranged for boarders. |
