died at Leyden on 17 April 1628, leaving a widow and ten children. At his funeral on 21 April Professor Adolf Vorst pronounced an eloquent Latin oration. His portrait appears in vol. ii. of Freher's ‘Theatrum.’

JACK, THOMAS (d. 1598), Scottish schoolmaster, was appointed minister of Rutherglen in the presbytery of Glasgow, in 1567, and subsequently became master of Glasgow grammar school. In 1570 he was presented by James VI to the vicarage of Eastwood in the presbytery of Paisley, and in August 1574 resigned his mastership. In 1577 his name occurs as quæstor of Glasgow University, along with the record of his gift of the works of St. Ambrose and St. Gregory to the university. In 1582 he was an opponent of the appointment of Robert Montgomery as archbishop of Glasgow, and from 1581 to 1590 he was thrice member of the general assemblies, and in 1589 a commissioner for the preservation of the true religion. He was imprisoned before 1591 with Dalgleish, Patrick Melville, and others. He died in 1598. His widow, Euphemia Wylie, survived till 1608, and a daughter, Elizabeth, became the wife of Patrick Sharpe, principal of Glasgow University. While master of Glasgow grammar school, Jack began a dictionary in Latin hexameter verse of proper names occurring in the classics. Andrew Melville encouraged and helped him; and he tells us that when he called on George Buchanan at Stirling, the great man interrupted his history of Scotland, the sheets of which were lying on the table, to correct Jack's book with his own hand. Robert Pont, Hadrian Damman, and other scholars also gave their aid. The dictionary, a work of considerable scholarship, was finally published as ‘Onomasticon Poeticum, sive Propriorum quibus in suis Monumentis usi sunt veteres poetæ, brevis descriptio poetica, Thoma Iacchæo Caledonio Authore. Edinburgi excudebat Robertus Waldegrave,’ 1592, 4to.

JACK, WILLIAM (1795–1822), botanist, was born at Aberdeen 29 Jan. 1795, and received his early education at that university. At sixteen years of age he graduated M.A., but an attack of scarlet fever prevented him from going to study medicine at Edinburgh. He came to London in October 1811, and passed his examination as surgeon in the next year. Having been appointed surgeon in the Bengal medical service, he left for his post on his eighteenth birthday. He went through the Nepal war in 1814–15, and after further service in other parts of India, he met Sir Stamford Raffles at Calcutta in 1818, and accompanied him to Sumatra to investigate the botany of the island. Broken down by fatigue and exposure, he embarked for the Cape, but died the day following (15 Sept. 1822). He published some papers on Malayan plants in the scarce ‘Malayan Miscellanies’ (two volumes printed in 1820–1 at Bencoolen), and these were reprinted by Sir W. J. Hooker thirteen years later. Jack's name is commemorated in the genus Jackia, Wallich.

JACKMAN, ISAAC (fl. 1795), journalist and dramatist, born about the middle of the eighteenth century in Dublin, practised as an attorney there. He ultimately removed to London and wrote for the stage. His ‘Milesian,’ a comic opera, on its production at Drury Lane on 20 March 1777, met with an indifferent reception (Biog. Dramat.; Genest, Engl. Stage, v. 554). It was published in 1777. ‘All the World's a Stage,’ a farce by Jackman in two acts and in prose, was first acted at Drury Lane, 7 April 1777, and was frequently revived. Genest (ib.) characterises it as an indifferent piece, which met with more success than it deserved. It was printed in 1777, and reprinted in Bell's ‘British Theatre’ and other collections. ‘The Divorce,’ ‘a moderate farce, well received,’ produced at Drury Lane 10 Nov. 1781, and afterwards twice revived, was printed in 1781 (ib. vi. 214). ‘Hero and Leander,’ a burletta by Jackman (in two acts, prose and verse), was produced ‘with the most distinguished applause,’ says the printed copy, at the Royalty Theatre, Goodman's Fields, in 1787. Jackman prefixed a long dedication to Phillips
