conjunction with Joseph Robertson, Gordon's History of Scots Affairs, 3 vols. (1853), Thomas Innes's History of Scotland, Civil and Ecclesiastical (the Life of Thomas Innes which he contributed to this volume was reprinted in the edition of Innes's Critical Essays, published in the Historians of Scotland series), and (1869) the index volume of the Illustrations of the Antiquities of Aberdeen and Banff. In 1861, his own work, by which he is best known, An Ecclesiastical History of Scotland from the Introduction of Christianity to the Present Time (it closes with the death of Bishop Skinner on 15 April 1857), in four volumes, was published at Edinburgh, and at once stamped him as the foremost authority on the subject in Scotland. Clear and unaffected in style, this work is learned and exact, but it suffers somewhat from the fact that his extreme scrupulosity as to literal truth caused him to hold too severely in check the wit and liveliness which were so conspicuous and charming in his conversation. As an historian he was determined to be fair, albeit he is at no pains to conceal (what he was proud of) his enthusiastic toryism and his profound attachment to the Scottish episcopal church. In the preface, Grub acknowledges the help he had received from Joseph Robertson and Mr. Norval Clyne; he regrets that for the history of the Roman Catholic church after the Reformation he had not been able to obtain more accurate materials; and he says that the work had occupied him more than nine years. In spite of the more recent researches on the Celtic period of Scottish history, the book is by no means out of date ; but it is unfortunate that no second edition of it was called for until Grub was too old to undertake the labour of preparing one. He had made notes for this which it is understood were lent to the Rev. W. Stephen, D.D., Dumbarton, for his History. Grub contributed to Chambers's Encyclopædia the articles Scotland and Church of Scotland; that on Scottish Literature in the earlier editions was also his, but failing health prevented him from undertaking its revision for the new edition. To the Aberdeen Philosophical Society, he contributed the Life of Bishop Elphinstone; The Life of Bishop Burnet, and his Character as a Historian and Biographer; Dr. James Beattie and his Friends; The Antiquities of Dunkeld; Froude's History and
