‎First printing of this paper in which he described his invention of the so-called ""HELIOCROMS"", a pioneer paper in the development of colour-photography. Niepce de Saint Victor discovered there was a connection between the color that chloride salt produced in a flame with the color light produced on a chloride salt-treated plate. Heliochrome was the name of this process, which enabled Mr. Niepce de Saint Victor to produce copies of color engravings and landscapes. He did not produce daguerreotypes, and soon learned that the images he produced using the heliochrome process were not fixed and began turning gray with increased light exposure. Applying transparent coatings did not prove effective, and therefore Mr. Niepce de Saint Victor soon abandoned this unfeasible method. However, his experiments with heliochrome did lead to the successful daguerreotype color process developed by a New York Baptist minister named Levi L. Hill (1816-1865).‎
