instituted a second chair of Hebrew in his favour. In 1620 he was sent by the States of Holland to induce Pierre Dumoulin or André Rivet to settle in that country; and after a second journey he was successful in inducing Rivet to comply with their request. Some time after the return of Erpenius, the states appointed him their interpreter; and in this capacity he had the duty imposed upon him of translating and replying to the different letters of the Moslem princes of Asia and Africa. His reputation had now spread throughout all Europe, and several princes, the kings of England and Spain, and the archbishop of Seville made him the most flattering offers; but he constantly refused to leave his native country. He was preparing an edition of the Koran with a Latin translation and notes, and was projecting an Oriental library, when he died prematurely on the 13th of November 1624.
Among his works may be mentioned his Grammatica Arabica, published originally in 1613 and often reprinted; Rudimenta linguae Arabicae (1620); Grammatica Ebraea generalis (1621); Grammatica Chaldaica et Syria (1628); and an edition of Elmacin’s History of the Saracens.
ERROLL (or Errol), FRANCIS HAY, 9th Earl of (d. 1631), Scottish nobleman, was the son of Andrew, 8th earl, and of Lady Jean Hay, daughter of William, 6th earl. The date of his birth is unrecorded, but he succeeded to the earldom (cr. 1453) in 1585, was early converted to Roman Catholicism, and as the associate of Huntly joined in the Spanish conspiracies against the throne of Elizabeth. A letter written by him, declaring his allegiance to the king of Spain, having been intercepted and sent by Elizabeth to James in February 1589, he was declared a rebel by the council. He engaged with Huntly and Crawford in a rebellion in the north of Scotland, but their forces surrendered at Aberdeen on the arrival of the king in April; and in July Erroll gave himself up to James, who leniently refrained from exacting any penalty. In September of the same year he entered into a personal bond with Huntly for mutual assistance; and in 1590 displeased the king by marrying, in spite of his prohibition, Lady Elizabeth Douglas, daughter of the earl of Morton. He was imprisoned on suspicion of complicity in the attempt made by Gray and Bothwell to surprise the king at Falkland in June 1592; and though he obtained his release, he was again proclaimed a rebel on account of the discovery of his signature to two of the “Spanish Blanks,” unwritten sheets subscribed with the names of the chief conspirators in a plot for a Spanish invasion of Scotland, to be filled up later with the terms of the projected treaty. After a failure to apprehend him in March 1593, Erroll and his companions were sentenced to abjure Romanism or leave the kingdom; and on their non-compliance were in 1594 declared traitors. On the 3rd of October they defeated at Glenlivet a force sent against them under Argyll; though Erroll himself was severely wounded, and Slains Castle, his seat, razed to the ground. The rebel lords left Scotland in 1595, and Erroll, on report of his further conspiracies abroad, was arrested by the states of Zealand, but was afterwards allowed to escape. He returned to Scotland secretly in 1596, and on the 20th of June 1597 abjured Romanism and made his peace with the Kirk. He enjoyed the favour of the king, and in 1602 was appointed a commissioner to negotiate the union with England. His relations with the Kirk, however, were not so amicable. The reality of his conversion was disputed, and on the 21st of May 1608 he was confined to the city of Perth “for the better resolution of his doubts,” being subsequently declared an obstinate “papist,” excommunicated, deprived of his estate, and imprisoned at Dumbarton; and after some further vacillation was finally released in May 1611. Lord Erroll died on the 16th of July 1631, and was buried in the church of Slains. He married (1) Anne, daughter of John, 4th earl of Atholl; (2) Margaret, daughter of the regent Murray; and (3) Elizabeth, daughter of William, 6th earl of Morton. By his third wife he had several children, of whom his eldest son, William, succeeded him. The dispute which began in his lifetime concerning the hereditary office of lord high constable between the families of Erroll and of the Earl Marischal was settled finally in favour of the former; thus establishing the precedence enjoyed by the earls of Erroll next after the royal family over all other subjects in Scotland.

ERROR (Lat. error, from errare, to wander, to err), a mistake, a departure or deviation from what is true, exact or right. For the legal process by which a judgment could be reversed on the ground of error, known as a “writ of error,” see Writ and Appeal. The words “error excepted” or “errors and omissions excepted” (contracted to “E.E.” “E. & O.E.”), are frequently placed at the end of a statement of account or an invoice, so that the accounting party may reserve the right to correct any errors or omissions which may be subsequently discovered, or make further claims in respect of them. In mathematics, “error” is the deviation of an observed or calculated quantity from its true value. The calculus of errors leads to the formulation of the “law of error,” which is an analytical expression of the most probably true value of a series of discordant values (see Probability).
ERSCH, JOHANN SAMUEL (1766–1828), the founder of German bibliography, was born at Grossglogau, in Silesia, on the 23rd of June 1766. In 1785 he entered the university of Halle with the view of studying theology; but soon his whole attention became engrossed by history, bibliography and geography. At Halle he made the acquaintance of J. E. Fabri, professor of geography; and when the latter was made professor of history and statistics at Jena, Ersch accompanied him thither, and aided him in the preparation of several works. In 1788 he published the Verzeichnis aller anonymischen Schriften, as a supplement to the 4th edition of Meusel’s Gelehrtes Deutschland. The researches required for this work suggested to him the preparation of a Repertorium über die allgemeinen deutschen Journale und andere periodische Sammlungen für Erdbeschreibung, Geschichte, und die damit verwandten Wissenschaften (Lemgo, 1790–1792). The fame which this publication acquired him led to his being engaged by Schütz and Hufeland to prepare an Allgemeines Repertorium der Literatur, published in 8 vols. (Jena and Weimar, 1793–1809), which condensed the literary productions of 15 years (1785–1800), and included an account not merely of the books published during that period, but also of articles in periodicals and magazines, and even of the criticisms to which each book had been subjected. While engaged in this great work he also projected La France littéraire, which was published at Hamburg in 5 vols., from 1797 to 1806. In 1795 he went to Hamburg to edit the Neue Hamburger Zeitung, founded by Victor Klopstock, brother of the poet, but returned in 1800 to Jena to take active part in the Allgemeine Literaturzeitung. He also obtained in the same year the office of librarian in the university, and in 1802 was made professor of philosophy. In 1803 he accepted the chair of geography and statistics at Halle, and in 1808 was made principal librarian. He here projected a Handbuch der deutschen Literatur seit der Mitte des 18. Jahrh. bis auf die neueste Zeit (Leipzig, 1812–1814) and, along with Johann Gottfried Gruber (q.v.), the Allgemeine Encyklopädie der Wissenschaften und Künste (Leipzig, 1818 ffg.) which he continued as far as the 21st volume. The accuracy and thoroughness of this monumental encyclopaedia make it still an indispensable book of reference. Ersch died at Halle on the 16th of January 1828.
ERSKINE, EBENEZER (1680–1754), Scottish divine, the chief founder of the Secession Church (formed of dissenters from the Church of Scotland), was born on the 22nd of June 1680, most probably at Dryburgh, Berwickshire. His father, Henry Erskine, who was at one time minister at Cornhill, Durham, was ejected in 1662 by the Act of Uniformity, and, after suffering some years’ imprisonment, was after the Revolution appointed to the parish of Chirnside, Berwickshire. After studying at the university of Edinburgh, Ebenezer became minister of Portmoak, Kinross-shire. There he remained for twenty-eight
