| Description | Written from 18 Duke Street, Westminster, London. The letter remarks on the serendipity of the fact that just when Brunel is turning his attention to the question of the revolving stand for stabilising navigational instruments being devised by Professor Piazzi Smyth, with support from Brunel, a detailed set of theories and calculations relating to the rolling and pitching of the ship has just been completed by one of his assistants. Brunel would like Professor Smyth's input before continuing on with the matter and sets out the problem as he sees it. |
