a river which rises on the confines of Picardy, and runs north-east by Cambrai, Valenciennes, Tournay, Oudenarde, &c. and receiving the Lis at Ghent, runs east by Dendermond, and then north to Antwerp; below which city it divides into two branch-

er, one called the Wesser-Scheld, which separates Flanders from Zealand, and discharges itself into the sea near Flushing; and the other called the Ooster-Scheld, which runs by Bergen-op-zoom, and afterwards between the islands Beveland and Schouwen, and a little below falls into the sea.

SCHENNER (Christopher), a German mathematician, astronomer, and Jesuit, eminent for being the first who discovered spots on the sun, was born at Schwaben in the territory of Middleheim in 1575. He first discovered spots on the sun's disk in 1611, and made observations on these phenomena at Rome, until at length reducing them to order, he published them in one vol. folio in 1630. He wrote also some smaller things relating to mathematics and philosophy; and died in 1660.
