Black vomit

( Med. ) A name given to a discharge of dark-colored bile from the stomach in certain diseases of the liver and biliary organs, and not unfrequently to the dark grumous blood emitted from the stomach in the disease known as hæmat emesis, or vomiting of blood; in both cases, however, it is only a symptom more properly appertaining to YELLOW FEVER, q. v. Black wall, ( black - wawl,) a suburb of London, on the E. side of the Thames, 4 m. E. of St. Paul's. Pop. 30,507. Here are the East and West India docks, and shipbuilding-yards. This suburb is connected with London by a railway, raised above the streets to almost a level with the roofs of the houses, on a brick viaduct. It is noted for its whitebait, a small and delicate fish, caught off here in the Thames. Black Wal'nut, in Illinois , a village of Ogle co. Black Walnut, in Virginia , a post-village of Halifax co., 138 m. S. W. of Richmond. Black Warrior River, in Alabama , formed by the junction of the Mulberry and Locust forks in Walker co., and taking a S. course, empties into the Tombigbee, above Demo polis.

Black Sea, (the EUXINE, or Pontos Euzienos of the Greeks, and Pontus Euxinus of the Romans; Turk. Caca Denisi; Ru . Czorno More,) a large internal sea lying Black'-visaged, a. Having a dark visage or countebetween the S.W. provinces of Ru ia in Europe and Asia Minor: extending from 40° 50′ to 46° 45′ N. Lat., and from 27° 30 to 41° 50′ E. Lon. It is bounded on the N. and N. W. by the Ru ian provinces of Taurida, Kherson, and Be arabia; on the N.N.E. by the Caucasian countries, Cir ca ia, Mingrelia, and I merit i a; on the S.E. and S. by Armenia and Asia Minor; and on the W. by the Turkish governments of Roumelia and Bulgaria. Its extreme length from E. to W. is upwards of 700 m.; its greatest width, on the 31st meridian, 380 m. Its surface is estimated at about 160,000 sq. m.; and its coastline, including its sinuosities, considerably exceeds 2,000 m. The B. S. is connected with the Sea of Azof by the Strait of Yenikalé (anc. Bosphorus Cimmerius), and with the Sea of Marmora by the Channel of Constantinople (anc. Bosphorus Thracius ). With these excерtions, it is wholly isolated. It is also much more compact in form than most other large bodies of water, having few large limbs, unle , indeed, the Sea of Azof and that of Marmora may be reckoned as gulfs. The straits of the B. S. are very remarkable, that of Yenikalé being not more than 2 m. acro , and that of Constantinople le than 12. The depth of water of this sea is very variable, deepening from 4 to 160 fathoms. There are no tides in this close sea, but the currents are very marked, powerful, and regular. The prevailing wind blows from the N.E. The B. S. teems with fish, although few fisheries exist on its shores. It receives the waters of more than 40 rivers, among which are the Danube, the Dniester, the Dnieper, the Bug, the Don, and the Kuban. Notwithstanding the horror entertained by the Greeks, or rather the Greek poets, of this sea, its shores are famous in their true and fabulous history. Colchis, the Temple of the Sun, and scene of the Argonautic expedition, were on its E. coast; the Cimmerian land of everlasting darkne was originally fixed upon its N. shore; and in more historical times, the Lydian, Persian, and Byzantine powers, and the exploits of Mithridates, illustrated its S. and S.W. borders. At an early period many Greek colonies were planted on its shores. Its commerce was also reckoned of first-rate importance. Athens drew from it her principal supplies of corn and naval stores; and it furnished the favorite slaves for the markets of Greece and Rome. From the time of Const an tine till the 15th century, it formed the centre of the Roman world, and during this period, a part at least of the Indian trade was carried on through it. The Venetians and Genoese were the condnetors of this traffic. Soon after the fall of Constantinople, in 1453, all but Turkish ve els were excluded Tuscaloosa.
