In Europe, the Arabs were the first to build observatories; the Giralda, or Tower of Seville, was erected under the superintendence of Geber the mathematician, about A. D. 1196, for that purpose. After the expulsion of the Moors it was turned into a belfry, the Spaniards not knowing what else to do with it. The same people mistook the vertical gnomons of Quito — beneath the line — for idols, and upset them, crossing themselves devoutly. Of the obelisks of Egypt, the round towers of Ireland, and the gnomons of Quito, the last is the least distinctly phallic. Native Observatory
ave it a yellow color, and the result — brass — was highly valued. Aristotle and Strabo refer to this earth, as do also Ambrosius, Bishop of Milan, fourth century; Primasius, Bishop of Adrumetum, in Africa, sixth century; and Isidore, Bishop of Seville, seventh century. These learned prelates mention an addition by which copper acquired a gold color. This was undoubtedly calamine. Albertus Magnus, A. D. 1280, seems to have suspected the truth; but it was reserved for Paracelsus, who died ter and brighter as years roll by, — tardy justice. Famous cannon of the world. In the eleventh century, if we may credit the chronicle of Alphonso VI., written by Pedro, bishop of Leon, the vessels of the king of Tunis, in the attack on Seville, had on board a number of iron pipes, out of which volumes of thundering fire were discharged. In the fourteenth century the references to the uses of cannon became common. Ferdinand took Gibraltar from the Moors by cannon, in 1308. Petrarc<

The same good — will toward Vespucci is displayed by Fernando Colon, who wrote the Life of his father in 1535 in Seville, four years before his death, and who, with Juan Vespucci, a nephew of Amerigo's, was present at the astronomical junta of Badajoz, and at the proceedings respecting the possession of the Moluccas. The confusion of dates in the numerous versitheir father in 1492, in which it was to be decided what parts of the new continent were first seen by Columbus. In the course of this suit it was never pretended that he had preceded Columbus in the discovery of the continent. Amerigo died at Seville, February 22, 1512. In 1520 maps were extant, having in them the name of America, proposed by Hylacomylus in 1507. Las Casas, in treating on the subject in an unpublished work, the Historia general de las Indias, says that the statement that
e air from the range of pipes above it. In organs of the largest class as formerly constructed the operation of the keys was a work requiring, in addition to musical skill, a large amount of hard bodily labor. It is said that the performer on the great Haarlem organ was obliged to strip preparatory to commencing his work, and retired covered with perspiration at the end of the hour's performance. This is one of the largest instruments in Europe, having 60 stops and 8,000 pipes. One at Seville has 5,300 pipes. The expenditure of wind varying greatly, according to the series of notes produced, the tension of the air supply was very different at different times, causing a variation in the purity of the tone and difficulty in opening the valves when under high pressure. These difficulties were remedied by the pneumatic lever of Barker, in which small subsidiary bellows operated by the movement of the key are employed to depress the wires by which the valves are opened.

the amount of westerly declination had been then long understood. That which belongs to Columbus is not the first observation of the existence of the variation (which, for example, is noted in the map of Andrea Bianco, in 1436), but the remark which he made on the 13th of September, 1492, that 2 1/2° east of the island of Corvo the magnetic variation changes, passing from N. E. to N. W. — Humboldt. The first variation-compass was constructed before 1525, by an ingenious apothecary of Seville, Felipe Guillen. So earnest were the endeavors to learn more exactly the direction of the curves of magnetic declination, that in 1585 Juan Jayme sailed with Francisco Gali from Manila to Acapulco for the sole purpose of trying in the Pacific a declination-instrument which he had invented. The cosmographer Alonso de Santa Cruz, one of the instructors of Charles V., undertook the drawing up of the first general Variation chart, although indeed from very imperfect observations, as earl
This earth was used for the specific purpose, but it was long ere the truth was elicited that calamine was a metallic ore, and yielded its base to form an alloy with the copper. See brass. Aristotle, Strabo, and various other writers refer to an earth which conferred a yellow color on copper. Brass was considered a more valuable kind of copper. Ambrosias, Bishop of Milan in the fourth century, Promasius, Bishop of Adrumetum, in Africa, in the sixth century, and Isidore, Bishop of Seville in the seventh century, mention an addition by which copper acquired a gold color. This was, undoubtedly, calamine. Albertus Magnus (1205-1280) speaks of calamine as a semimetal. The furnace-calamine, or sublimated zinc, with which the furnaces and chimneys were lined, where zinc-yielding ores were smelted, was thrown aside as useless until the middle of the sixteenth century. It had a place in the pharmacopoeia, but this use required but a small portion of the quantity produced.
