Log entries for the return journey, travelling via Fayal [Faial] in the Azores to Spithead, near Plymouth, where the ship anchored on 29 July. Entries for the 13-18 July record that when the ship anchored in Fayal Bay Wales went on shore with his instruments to take observations by which he found that the watch was too fast for mean time; he goes on to say that he had a troublesome job of adjusting the instrument [RGO 14/58: 183-183v]. The final entries after landing at Spithead recount how Wales went ashore with Captain Cook and brought Mr Kendall’s watch to compare with the clock of the Royal Academy at Portsmouth, where it was found that the watch was too fast, the total error of longitude being 47 degrees by his calculations. The last entry records that he returned the watch to Nevil Maskelyne, the Astronomer Royal, at Greenwich [RGO 14/58: 186v].
