In central Africa the chimpanzees assume more or less marked gorilla-like traits. The first of these aberrant types is Schweinfurth's chimpanzee (_Anthropopithecus troglodytes schweinfurthi_), which inhabits the Niam-Niam country, and, although evidently belonging to the same species as the typical race, exhibits certain gorilla-like features. These traits are still more developed in the bald chimpanzee (_A. tschego_) of Loango, the Gabun, and other regions of French Congo, which takes its English name from the sparse covering of hair on the head. The most gorilla-like of all the races is, however, the kulu-kamba chimpanzee (_A. kulu-kamba_) of du Chaillu, which inhabits central Africa. The celebrated ape "Mafuka," which lived in the Dresden zoological gardens during 1875, and came from Loango, was apparently a member of this species, although it was at one time regarded as a hybrid between a chimpanzee and a gorilla. These gorilla-like traits were still more pronounced in "Johanna," a female chimpanzee living in Barnum & Bailey's show in 1899, which has been described and figured by Dr A. Keith. The heavy ridges over the brow, originally supposed to be distinctive of the gorilla, are particularly well marked in "Johanna," and they would doubtless be still more noticeable in the male of the same race, which seems to be undoubtedly du Chaillu's kulu-kamba. Still the large size and prominence of the ears proclaim that both "Mafuka" and "Johanna" were chimpanzees and not gorillas. A gorilla-like feature in "Johanna" is, however, the presence of large folds at the sides (_ala_) of the nostrils, which are absent in the typical chimpanzee, but in the gorilla extend down to the upper lip. Chimpanzees exhibit great docility in confinement, where, however, they seldom survive for any great length of time. They likewise display a much higher degree of intelligence than any of the other man-like apes. (See PRIMATES.) (R. L.*)
CHINA, a country of eastern Asia, the principal division of the Chinese empire. In addition to China proper the Chinese Empire includes Manchuria, Mongolia, Tibet and Sin-kiang (East Turkestan, Kulja, Dzungaria, &c., _i.e._ all the Chinese dependencies lying between Mongolia on the north and Tibet on the south). Its most southern point is in 18° 50' N.; its most northern in 53° 25' N.; its most western in 74° E., and its most eastern in 135° E. It lies, however, mainly between 20° and 50° N. and 80° and 130° E. It is considerably larger than the whole of Europe. Though its area has not been exactly ascertained the various estimates closely approximate, varying between 4,277,000 and 4,300,000 sq. m. It is bounded N.W., N. and N.E. by Asiatic Russia, along a frontier extending some 6000 m.; E. by Korea and those parts of the Pacific known as the Yellow Sea and China Sea; S. and S.W. by the China Sea, French Indo-China, Upper Burma and the Himalayan states. It is narrowest in the extreme west. Chinese Turkestan along the meridian of Kashgar (76° E.) has a breadth of but 250 m. It rapidly broadens and for the greater part of its area is over 1800 m. across in a direct N. and S. line. Its greatest length is from the N.E. corner of Manchuria to the S.W. confines of Tibet, a distance of 3100 m. in a direct line. Its seaboard, about 5000 m. following the indentations of the coast, is almost, wholly in China proper, but the peninsula of Liao-tung and also the western shores of the Gulf of Liao-tung are in Manchuria.
