An excellent survey of photographic processes to date. The largest portion is devoted to the daguerreotype - Valicourt was a practitioner of the process and here provides full descriptions of apparatus and chemicals, plates (including daguerreotype) and the various paper processes in use: collodion, albumen and gelatin, etc. Also includes photomechanical techniques.

Valicourt had previously written a few short pieces which appeared as chapters in texts by Smee, and a text on Blanquart-Evrard's paper process from the mid 1840s; in this title he has borrowed and distilled from the the discoveries of Niépce, Daguerre, Fox Talbot, Herschel, Hunt, Blanquard-Evrard, Niepce de St.-Victor, Fizean, Claudet, et al. To call this volume a " Nouvelle édition" is an exaggeration; it is considerably revised and enlarged from the 1851 editiont, and one of the superior compendiums of known photographic processes to date.
