PERCY, John (1817-1889). Metallurgist.
Autograph Letter Signed to Gowland, 1 page 8vo, on embossed writing paper of the Museum of Practical Geology, 24 January 1872. Thanking Gowland for an 'interesting specimen' and reporting that he can think of no new explanation for the event.

'Since I wrote to you yesterday we have received another unexpected letter from Ockham, of a date 15 days earlier than the one I told you of. On July 26th, in sight of Brava (one of the Cape de Verde Islands), the Swift spoke a Dutch Barque. This barque posted letters from the Swift, in Holland after her arrival there.
 'Doubtless the barque was a slow vessel, besides which the Zuyder Zee is further to go than England.'
