Three volumes, for 1839, 1843, 1844.

The 1839 volume contains the first printing of the official announcement of Daguerre's invention of the photographic process. Arago's report contained within preceded the official report in Comptes Rendues which was published at the end of 1839 (in the July-December issue). This notice also preceeded Daguerre's own publication of 1839 "Historique et description du daguerréotypie."

The 1843 volume contains Arago's report of Daguerre's new polishing and plate preparation methods.

The 1844 volume continues with further improvements by Daguerre in sensitizing methods.

THIS LOT IS A GENEROUS DONATION FROM JEFF GREEN
