| Description | Commences with an apology for not answering Fox's letter of 1843, describing his great pressure of work on reaching port. Outlines his work with a magnetic dipping needle at the Cape, on an island in the Korean archipelago and in Japan. Discusses discrepencies in his readings and the state of his equipment. Comments on the time he was allowed in landing in Japan, 'more than they have granted to any preceding one for more than 40 years'. His relative freedom of movement in the Korean group is noted and success in overturning local prejudices. He sends his dip observations to Fox and describes some additional instruments and adaptions he is working on. |
