Oeuvres complètes. Publiées sous la direction de J.-A. Barral
The collected works of French astronomer and physicist François Arago, edited by J.-A. Barral and issued in Paris by Gide et J. Baudry from 1854 for scientific readers. Text figures are line diagrams of optics and polarization: labelled axes, ray paths, arrow-marked light beams, hatched mirrors and prisms, dashed construction lines—usable as spare geometric marks and instrument schematics.
