15, and Append. p. 6, fol.) On 27 Aug. 1553 he prudently obtained leave of absence from college for a month on urgent private affairs. The following day letters were received from the queen commanding that all injunctions contrary to the founder's statutes issued since the death of Henry VIII should be abolished; and Haddon having retired, Oglethorp was re-elected president on 31 Oct. A commission for Haddon's admission to practise as an advocate in the arches court of Canterbury was taken out on 9 May 1555 (Tanner, Bibl. Brit. p. 367; Coote, English Civilians, p. 41). He was admitted a member of Gray's Inn in 1557, and was one of the members for Thetford, Norfolk, in the parliament which assembled 20 Jan. 1557-8 (Foster, Gray's Inn Register, p. 27; Official List of Members of Parliament, i. 397). In 1557 he translated into Latin a supplicatory letter to Pope Paul IV from the parliament of England, to dissuade his holiness from revoking Cardinal Pole's legatine authority. His sympathy with protestantism was, however, displayed in a consolatory Latin poem addressed to the Princess Elizabeth on her afflictions. On her accession he was summoned to attend her at Hatfield, congratulated her in Latin verse, and was immediately constituted one of the masters of the court of requests. In spite of his protestant opinions he was an admirer of the learning of Bishop Cuthbert Tunstal, and composed the epitaph placed on his tomb in 1559. On 20 June in that year he was appointed one of her majesty's commissioners for the visitation of the university of Cambridge and the college of Eton; and on 18 Sept. following the queen granted him a pension of 50l. per annum. He was in the commission for administering oaths to ecclesiastics (20 Oct, 1559); was also one of the ecclesiastical commissioners; and received from his friend, Archbishop Parker, the office of judge of the prerogative court (Strype, Life of Parker, p. 365, fol.) In 1560 a Latin prayer-book, prepared under the superintendence of Haddon, who took a former translation by Aless (see Alesius, Alexander) as a model, was authorised by the queen's letters patent for the use of the colleges in both universities and those of Eton and Winchester (Clay, Liturgical Services in the Reign of Elizabeth, pref. p. xxiv). On 22 Jan. 1560-1 he was one of the royal commissioners appointed to peruse the order of lessons throughout the year, to cause new calendars to be printed, to provide remedies for the decay of churches, and to prescribe some good order for collegiate churches in the use of the Latin service. He was one of the learned men recommended by Bishop Grindal in December 1561 for the provostship of Eton College, but the queen's choice fell upon William Day. In June 1562 he and Parker, at the request of the senate, induced Cecil to abandon his intention of resigning the chancellorship of the university of Cambridge (Life of Parker, i, 118).
In 1563 Jerome Osorio da Fonseca, a Portuguese priest, published in French and Latin an epistle to Queen Elizabeth, exhorting her to return to the communion of the catholic church. Haddon, by direction of the government, wrote an answer, which was printed at Paris in 1563 through the agency of Sir Thomas Smith , the English ambassador. In August 1564 Haddon accompanied the queen to Cambridge, and determined the questions in law in the disputations in that faculty held in her presence (Cooper, Annals of Cambridge, ii. 196). In the same year the queen granted him the site of the abbey of Wymondham, Norfolk, with the maaor and lands pertaining to that monastery. He was employed at Bruges in 1565 and 1566 with Viscount Montacute and Dr. Nicholas Wotton, in negotiations for restoring the ancient commercial relations between England and the Netherlands. In November 1566 he was a member of the joint committee of both houses of parliament appointed to petition the queen about her marriage (Parliamentary History, 1763, iv. 62).
Osorio, who had been meanwhile created bishop of Silves, published in 1567 a reply to Haddon, and the latter commenced a rejoinder. It was left unfinished at the time of his death, but was ultimately completed and published by John Foxe. There appeared, probably at Antwerp, without date, 'Chorus alternatim canentium,' a satire in verse on the controversy between Haddon and Osorio, attached to a caricature in which Haddon, Bucer, and P. V. Vermigli are represented as dogs drawing a car whereon Osorio is seated in triumph. According to Dr. Edward Nares the English jesuits at Louvain sought to deter Haddon from proceeding with his second confutation of Osorio, 'endeavouring to intimidate him by a prophetic denunciation of some strange harm to happen to him if he did not stop his pen.' He died, adds Nares, in Flanders, whence the warning came, and his death naturally raised suspicions of foul play (Life of Lord Burghley, ii. 306, 307). The Rev. George Townsend says that Haddon died at Bruges after being threatened with death if he continued the controversy with Osorio (Life of Foxe, pp. 209-11). As a matter of fact, however, Haddon died in London on 21 Jan. 1571-2, and was interred on the 25th at Christ Church,
