Ebers, Georg Moritz
Georg Moritz (1837-1898), an eminent German scholar and novelist. He was a remarkable student when a young man. In early life he began to apply himself to the study of ancient remains in Egypt. In 1868 he was appointed professor of Egyptian language, history, and antiquities at Jena. Two years later he became professor of Egyptology in the University of Leipsic. He visited Egypt repeatedly and was instrumental in making excavations revealing numerous specimens of Egyptian art, and in the discovery of valuable papyrus manuscripts. His university duties were but nominal. He wrote a large number of works relative to Egypt, in which he discussed the manuscripts, statuary, architecture, and hieroglyphic inscriptions. Among his writings is a popular work called Egypt in Picture and Word. He also wrote a series of novels descriptive of ancient Egyptian and Syrian life. The more noted are An Egyptian Princess, Uarda, Homo Sum, The Sisters, Serapis, and Kleopatra. At the time of his death, he was, as might be expected naturally, the leading authority on all matters pertaining to ancient Egypt.

Ebony
a name given to various woods. They may be described as heavy, dark, hard woods suitable for carving, ornamental cabinet work, canes, and musical instruments. The ebony family, which, it may be noted, does not contain all the woods known in commerce as ebony, comprises several genera and about 250 species of shrubs or trees. The most valuable of the ebony trees belong to the genus Diospyros, and are confined to the warmer regions of the world, particularly to Asia, Mauritius and Africa. One species of this genus is the Virginian, or common persimmon. The most noted ebony, that having the blackest and finest grain, is obtained from the forests of Mauritius and Ceylon. Logs two feet in diameter are not unusual. A Japanese persimmon, cultivated for its fruit, also yields wood much prized by the Japanese artists for carving. A Jamaican tree, belonging to the legume family, furnishes a green "ebony," which takes a beautiful polish and is much used for inlaying. A dark brown "ebony," having the qualities of genuine ebony in all but color, is obtained from the forests of British Guiana. Genuine ebony takes a polish like ivory, and is almost as hard.

Ebro
a river in Spain, which has its source in the province of Santander, about 25 miles S. of the Bay of Biscay, and after a S. E. course of about 500 miles enters the Mediterranean. Its navigation is much interrupted by rapids and shoals, to avoid which a canal about 100 miles long has been constructed nearly parallel to its course.

Ebullition
When water is heated bubbles of vapor form at the bottom, rise to the cooler water above, and are condensed. As the heat continues, however, these bubbles reach the surface and escape into the air, causing the agitation called boiling or ebullition. The boiling-point of a liquid is determined by the temperature at which ebullition takes place. Water boils at 212 deg., sulphuric ether at 96 deg., alcohol at 176 deg., oil of turpentine at 316 deg., sulphuric acic at 620 deg., mercury at 662 deg.

Ecbatana

Its site can no longer be fixed with certainty, though many explorers agree in identifying it with the modern Hamadan.

Eccentric-clamp
An arrangement for lifting finished stonework, which might be made useful in the foundry for lifting cores of some descriptions, and thus obviate the necessity for hooks and staples. The weight of the object turns eccentrics, which bind rubber-faced plates firmly against the sides. The width is adjusted by turn-buckles at the sides.

Ecclesiastes
the title by which the Septuagint translators rendered the Hebrew Coheleth (the gatherer of the people), a symbolic name explained by the design of the book and the dramatic position occupied by Solomon in it, one of the canonical books of the Old Testament. According to Jewish tradition it was written by Solomon; but the best modern criticism has dede' cided that its style and language, no less than its thought, belong to a much later date.

Ech-Uisque
A Gaelic word meaning water-horse. The Ech-uisque was a goblin of Highland folk-lore, understood Egbo, The: or Esik, is a secret society of Calabar, near the to be a favourite form assumed by the Kelpie, in order to lure souls to his master the Devil . In the disguise of a fine steed, beautifully accoutred, the Kelpie grazed innocently by the wayside. The weary traveller, passing by, and believing this splendid animal to have strayed from his master, was tempted to make use of him to help him on his way; and the deceitful Kelpie, remaining quiet as a lamb until the traveller was fairly mounted, would then with a fiendish yell of triumph plunge headlong into an adjacent pool. It was believed that the soul of the unfortunate man, who had had no time to prepare for death, would thus be safely secured to the Evil One; while the Kelpie received the body in payment for his trouble.

Echo
a sound returned to its source. If a person speaks against a wall or cliff the wave of sound is sent back again, and the speaker hears the sound of his own voice as though someone in the distance were calling to him. Under ordinary conditions sound travels at a rate of 1,080 feet per second. The time elapsing between the call and the return of an echo gives a clue to the distance of the reflecting surface. The reflecting surface must be a concave or, if flat, it must stand squarely across the path of the sound, or else the sound wave will glance off in another direction and fail to return to the speaker. Many caves and mountain passes have celebrated echoes. Some public halls echo to such an extent that it is difficult to address an audience. In such cases cloth hangings are a help.
