He held many appointments, and executed many commissions, not a few of them of the highest responsibility and dignity, but most of them sought him, not he them. Lord Cassilis had him for tutor-companion (1532-37). King James V. engaged him as tutor for one of his children (1538-39). The King of Portugal employed him to aid in founding and conducting his College at Coimbra, and did his best, though in vain, to retain him in his kingdom (1547-52). The famous Maréchal de Brissac chose him to mould the mind of his son, and sometimes had him at a Council of War (1555-60). Queen Mary attached him to her Court, and as we have seen, read Livy with him, and, no doubt, much else (1562). The General Assembly of the Reformed Church of Scotland chose him, though a layman, as their Moderator (1567), he having already sat four years as a member and aided them in drawing up their _First Book of Discipline_. He was appointed by Regent Moray Principal of St. Leonard’s College, St. Andrews (1566), to reorganise its curriculum and constitution. He was selected as Secretary to the Commission sent by the Scots Government to deal with the high questions at issue between Queens Elizabeth and Mary (1568-69). The Scots Parliament chose him to the extremely responsible office of Tutor to the youthful King James VI. (1570), and continued him in that position nominally until his death (1582). He sat as a member of the Scots Parliament (1570-78) in virtue of his keepership of the Privy Seal, and did secretarial work for it, which nobody else was qualified to do, while at the same time assisting the General Assembly in revising their Book of ‘Policy.’ This keepership he may have solicited--he subsequently resigned it--although there is no proof of that, but all the other appointments came to him, and engaged his best ability as they passed him in procession. _Sir James Melville backs Scaliger_
