CAIRO (400), cap. of Egypt, and largest city in Africa, on the right bank of the Nile, just above the Delta, 120 m.  SE. of Alexandria, covers an extensive area on a broad sandy plain, and presents a strange agglomeration of ancient and modern elements.  The modern city is the fourth founded in succession on the same site, and remains of the former cities are included in it, old walls, gateways, narrow streets, and latticed houses, palaces, and 400 mosques.  These, though much spoiled by time and tourists, still represent the brightest period of Saracenic art.  The most modern part of the city consists of broad boulevards, with European-built villas, hotels, &c., and has all the advantages of modern civic appliances.  There is a rich museum, and university with 2000 students.  Extensive railway communication and the Nile waterway induce a large transport trade, but there is little industry.  The population is mixed; the townsfolk are half Arab, half Egyptian, while Copts, Turks, Jews, Italians, and Greeks are numerous; it is a centre of Mohammedan learning, and since 1882 the centre of British influence in Egypt.
