Dulce. I. A Lake Of Guatemala, on the E. coast, near the gulf of Honduras, with which it communicates through a smaller lake, called the Golfete, and the river Dulce or Angostura. It is also called Lake Izabal. It is about 30 m. long by 12 broad, and has from 30 to 60 ft. of water in the deeper parts, shoaling gradually toward the shores. It is formed apparently by the expansion over a valley of the waters of the river Polochic, which enters it on the west. On its S. bank is the little village of Izabal. The Golfete is 15 m. long by 3 broad, and has a depth of from 12 to 15 ft. The Rio Dulce, through which both lakes reach the sea, is a narrow strait winding through densely wooded and almost perpendicular hills. A bar at its mouth prevents the entrance of vessels drawing over 6 ft. On the left bank is the little village of Livingston, named after the founder of the Louisiana code, which was once adopted in Guatemala. II* A gulf of Costa Rica, on the Pacific coast, formed by a peninsula whose point. Cape Matapalo, is in lat. 8° 3' N., Ion. 83° 15' W. It covers an area of about 800 sq. m. A river of the same name flows into the gulf near its N. extremity, after a course of 75 m.

III. A river of the Argentine Republic, which rises in the mountainous district of the province of Tucuman, about lat. 25° 45' 8., Ion. 65° 50' W., and after a S. E. course of 400 m. loses itself in Lake Porongos. According to some authorities, it passes through the lake and empties into the Rio Salado. Its banks are low and are often inundated in the wet season. Above Santiago it is called the Hondo, and at its head the Tala.
