44 Queen Ann St <1>
Friday
Dear Sir
As I believe you take in the Comptes Rendus, could you lend me the last number for a day or two, as I believe it contains an explanation by M. Daguerre <2> concerning the priority of M. Niepce <3> or himself in Heliography <4> –
It seems that Biot <5> has succeeded with the Moon’s rays, in exciting phosphorescence –
Believe me Yours very truly
H. F. Talbot
