BOUGUER, Pierre (1698-1758). Traité d'optique sur la gradation de la lumiere. Edited by l'Abbé Nicolas Louis de la Caille. Paris: H. L. Guerin & L. F. Delatour, 1760.
4o (252 x 192 mm). 7 folding plates, woodcut title vignette and tailpieces. Contemporary cat's-paw calf, spine gilt (joints starting, minor wear at spine ends).
FIRST EDITION of Bouguer's second and expanded work on photometry, completed just before his death and published by his friend, the astronomer l'Abbé Nicolas Louis de la Caille. "The Traité goes far beyond the Essai, describing a number of ingenious kinds of photometers ... and even attempting an elaborate theory of the reflection of light from rough surfaces, although this was not successful. The third and last part of the book, however, gives a valid elementary theory of the horizontal visual range through an obscuring atmosphere, arriving at a law, usually credited to H. Koschmieder, considered to belong to the twentieth century" (DSB). Norman 286.
