FIRST EDITION OF THE FIRST ANNOUNCEMENT OF THE DISCOVERY OF THE BLIND SPOT IN THE EYE. Mariotte's first work immediately embroiled him in a controversy that lasted until his death over the seat of vision. His experiments to determine what happened to light rays striking the base of the optic nerve led him to the discovery of the blind spot, or defect of vision in the eye, as he called it. As a result he abandoned the traditional view that images in the eye are formed on the retina, and became involved in a dispute over this with his fellow academician, the anatomist Jean Pecquet. A series of experiments carried out before the Academy in August 1669 widened the area of disagreement between the two, as did Perrault's support of Pecquet. Pecquet's letter disputing Mariotte's claim is included in this work. VERY RARE. Garrison-Morton 1481.1; Norman 1439.
