Einstein
ALBERT, a Swiss physicist, born in 1875. For a time he held a chair in the Zürich Polytechnic School, and was also for some years a professor in the University of Prague. Later he held a research position in an institution affiliated with the University of Berlin. In 1914 he protested against the manifesto of the German professors. Einstein came into prominence through his theory of relativity, which grew out of his participation in the effort to explain the Michelson-Morley experiment, on the socalled ether-drift of the eart the earth and its negative result. The principle of the theory is the conception of time as a fourth dimension. His theory of relativity was published in 1905 in a book, "Annalen der Physik." It was further expounded in 1916. This principle of relativity and the deflection of light by gravitation was considered by scientists the most revolutionary discovery in physical science since Newton. In April, 1921, Dr. Einstein visited the United States in behalf of the Zionist movement.

El Dorado
el do-ra'do, a mythical country, supposed to exist somewhere in South America . From the accounts given by the Indians, the Spanish explorers long believed a region existed somewhere in the Andes where gold was so abundant that children played with nuggets instead of marbles. Many expeditions were sent out to search for this land of gold, but, although much treasure was obtained, El Dorado was never discovered. During the gold excitement in California the region was called the El Dorado of the West. The term is Spanish, meaning gilded man, referring to the reputed high priest of this fabled region. The El Dorado myth is distinctly American, but seems related in many respects to the story of the Golden Fleece and other myths of Greece.

Elastic Moulds
These moulds are for the purpose of obtaining casts, in plaster or wax, from medals and other objects having parts that are undercut. The moulds are made by surrounding the object with a barrier of clay as high as the thickness of mould required, and, after oiling the surface, filling the space with melted glue, which, when cold, can if necessary be cut in suitable pieces for delivering smoothly. The pieces, when put together again, form the mould in which to run the plaster or wax. If the undercutting is not too deep, these moulds will yield sufficient to admit of ordinary flat casts being taken whole, without cutting. See PLASTER-CASTS; UNDERCUT.

a drug obtained from the fruits of the squirting cucumber, a native of the S. of Europe, common on rubbish in the villages of Greece and the Archipelago. The fruit breaks from its stalk, and and violently expels its seeds with the surrounding mucus through the opening thus made. This is not due to any true contractility, but much, in fact, as ripe gooseberries burst after prolonged rainy weather. It is the thick green mucus surrounding the seeds which yields the elaterium. Elaterium is used in medicine as a drastic hydragogue cathartic. Its active principle is a body called elaterin, C20H28O5, which is probably the most powerful purgative known, the ordinary dose being only from 1/40 1/4 to 2/10 grain. Both elaterium and elaterin are officinal in the British pharmacopeia. It is an exceedingly drastic purgative, used in dropsy.
