A Compleat System of Opticks, Cambridge: for the author, 1738, 2 volumes, 4°, 83 engraved folding plates (upper pastedowns to both volumes removed, some ink staining and manuscript annotations, short tears to a few plates), contemporary panelled calf gilt (rebacked, upper board of volume I detached, spines worn).
