It is no part of the purpose of this notice to describe his various works in detail, but the mere enumeration of them will show what a life of unremitting study he lived. Besides those already referred to, he edited, along with the late Dr Struthers, in 1874, 'The Minutes of the Westminster Assembly from November 1644 to March 1649,' to which is prefixed an elaborate Historical Introduction written by himself; in 1882 he wrote a 'Historical Notice of Archbishop Hamilton's Catechism' (first printed at St Andrews in 1551), prefixed to Paterson's black-letter reprint of the same; in 1883 he published his Baird Lecture, 'The Westminster Assembly: Its History and Standards'; in 1886 he published 'The Catechisms of the Second Reformation'; in 1888 he edited, for the Scottish Text Society, 'The Richt Vay to the Kingdome of Heuine,' by John Gau, the earliest known prose-treatise in the Scottish dialect setting forth the doctrines of the Reformers; and in 1897, for the same Society, 'The Gude and Godlie Ballads,' reprinted from the edition of 1567, with a full and most interesting Introduction. For the Scottish History Society he also edited in 1892 and 1896, along with the writer of this sketch, two volumes of 'The Records of the Commissions of the General Assembly,' covering the period 1646-1650, from the original manuscript in the Assembly library, with an introduction, notes, and appendices by himself. To these must be added the present volume of the Baird Lecture, 'The Scottish Reformation.' The Baird Lecture on the Westminster Assembly was received with great favour in America as well as in this country, and a new edition of it was published at Philadelphia in 1897, in a notice of which in the 'Presbyterian and Reformed Review' the following statement occurs: "The book at once took its rank as the most trustworthy and sympathetic account of the Westminster Standards in existence, and rapidly ran out of print. The public is to be congratulated that Dr Mitchell has permitted himself to be persuaded by the [Presbyterian] Board to revise the text and allow a new edition to be issued to meet the present demand. The revision does not much alter the text. A phrase is more felicitously turned here or rendered a shade more exact or emphatic there; a few additional references are added in the notes; and a few additional citations and remarks incorporated in them: that is about all. But so good a book needed only these little touches of betterment."
