CHEVREUL, Mémoire sur la vision des couleurs matérielles, 1882

First edition of Chevreul's last works on color.
A rare offprint with its own title page published by Firmin-Didot in 1882, of an article presented to the Academy of Sciences in December 1880 and January 1881 (one generally only finds the article extracted from the Mémoires de l'institut published in 1883). Chevreul is interested here in physiological optics, trying to analyze how the contrast between complementary colors is affected by movement.
In his conclusion, in which he calls himself "the dean of students in France" (he was then 95 years old), he sees a direct application of his work to signaling for train drivers.
