In August 1855 he married his second wife,—the daughter of his friend Cosmo Innes, and writer of the present Memoir. As is natural, she devotes a considerable proportion of the Memoir to recollections of the subsequent six-and-twenty years of her husband’s life. Till March 1861 they remained in Lauriston Place,—where three more children were born to Dr. Burton, a son and two daughters; but in that month they entered on the tenancy of Craighouse, a quaint old-sixteenth century fortalice, near the Braid Hills, and two miles out of Edinburgh, on which they had set their hearts, partly for the charm of its own ruinous picturesqueness, partly for its historical associations with the reigns of Queen Mary and James VI., and partly on account of the singular beauty of the views in its vicinity. Here, having reduced the ruin into habitable and pleasant order, they lived till 1878, on the verge of the Edinburgh world, and sufficiently close to it for the daily business purposes of such an inveterate pedestrian as Burton, but still so much out of it that the recluse evening habits into which he had settled could be interrupted only when he chose, whether by the reception of a friend or two now and then under his own roof, or by the still rarer accident of a visit to some friend’s house in town. Incidents of those seventeen years at Craighouse, besides the birth of his seventh child and youngest son, were his honorary graduation as LL.D. by the University of Edinburgh, his election to the membership of the Athenæum Club in London, his appointment to the dignity of the Historiographership-Royal for Scotland, and his honorary graduation as D.C.L. by the University of Oxford. These honours were successive acknowledgments of that growth of his literary reputation which had attended the appearance of such results of his continued industry for Blackwood as his _Book-Hunter_ and his _Scot Abroad_, but, above all, the publication of his completed _History of Scotland_ in eight volumes. Hardly had this last, his largest, work been finished when he projected his _History of the Reign of Queen Anne_.
