ALDUABIS (anc. geog.), a river of Celtic Gaul, which rising from Mount Jura, separating the Sequani from the Helvetii, and running through the county of Burgundy, or the Franche Comté, environs almost on every side the city of Besançon; and running by Dole, falls into the Saône near Chalons. In Cæsar it is called Alduabubis; in Ptolemy, Dubis: now le Doux.
