Arago's January 1839 announcement of Daguerre's discoveries, and the August 1839 publication of the manual attracted Macedonio Melloni, 1798 - 1854, an Italian physicist, largely concerned with the study of radiant heat and its physical properties and similarities to light, to embark on mastering the daguerréotype process; he found it to be woefully vague and without scientific basis. In this report, Melloni shows that in a few weeks, he was able to study the action of various chemicals, such as chlorine, iodine, and thoisulfate on silver plates and paper, and measure the action of different colors of the spectrum. On 12 November, 1839, Melloni delivered what is considered the first scientific paper on photography to the Royal Academy of Sciences in Naples, which was immediately published, and here republished with important additions.
This French edition, which was translated by Alfred Donné and edited by Guillaume Libri, adds a description of Donné's process for etching and subsequently printing directly from daguerréotype plates, which was the first photomechanical process.
