references: DSB ["The Traité des sens, Le Cat's most important work, grew as much out of his researches in physics as in physiology. In it Le Cat presented a theory of the propagation of light contrary to that of Newtonian attraction. He further reported on the pigmented choroid coat of the eye and assigned it a common embryonic origin with the pigment of the skin."].
