the university at that place was founded A. D. 968. At this distinguished seat of learning was educated the famous Gerbert of Auvergne. This enlightened ecclesiastic was successively a schoolmaster at Rheims (where he introduced the abacus, the Arabic numerals, the clock, the organ, and the globe), archbishop of Ravenna, and, eventually, Pope Sylvester II., to which position he was elevated by the decree of the Emperor Otho III. Patron and prelate died of poison shortly after, about A. D. 1002. Gerbert was probably the first to use in a Christian school the nine digits and a cipher, which proved, as William of Malmesbury said, a great blessing to the sweating calculators. A translation of Ptolemy, published in Spain in 1136, used the Hindoo notation. The Hindoo numerals were introduced into England about A. D. 1253. The accounts of the kings of England, previous to the Norman Conquest—and the same is probably true of most contemporary European nations—were calculated by r

hedral of Winchester in England were provided with organs. At this time and for two centuries later, the compass was small, usually from 9 to 11 notes, the brass pipes harsh in tone and the machinery clumsy; the keys being 4 or 5 inches broad, and struck by the fist. Gerbert of Auvergne, in his school at Rheims, had an organ played by steam. He was afterward made Pope by the Emperor Otho III., assuming the name of Sylvester II. He and his patron were poisoned by Italian intriguers about 1002. Gerbert introduced the Arabic numerals into Europe. The organ of Winchester, probably placed there by St. Dunstan, had 26 pairs of bellows, 400 pipes, and required 70 men to work it. The key-board is distinctly described at the close of the eleventh century. At this time a number of small bellows, 20 or more, were used, worked by men who held to a horizontal rail and operated the bellows with their feet, as at F, Fig. 3425. It is said that half-notes were invented at Venice in the tw

pendulum, and his friend and fellow-philosopher, Gerbert, invented the escapement, as it is believed. Gerbert became, successively, schoolmaster at Rheims (where he had a clock), Archbishop of Ravenna, and Pope Sylvester II. He died by poison in 1002. So did his patron, Otho III., about the same time. An oscillating arm was substituted for the fly, probably in the fourteenth century. The clock of Henry de Wyck, erected in 1364, for Charles V. of France, was regulated by an alternating bas offensive to insect vermin. The leaves are treated by heat and chemical reagents to separate the fibers and remove the resin. The invention is credited to M. Pannewitz. Bib. Univ. De Genevi, June, 1852, page 165.

l; Cul-Tivator; hoe; plow, etc. Fig. 4810 is one form of seeding-machine having hollow shares drawn by dragbars, and dropping into the furrow the seed which is uniformly fed from the hopper above. In Fig. 4811, the seed mechanism is actuated by the roller, which forms the earth into ridges, for protection of the seed. The relative vertical position of the parts is adjustable, to regulate the depth of planting. The rear rollers cover the seed. See also grain-drill, Fig. 2278-81, pages 1002-4. Seed-drill.
