As a controversial writer, and the able exponent of his peculiar views of ecclesiastical polity, Hugh Miller at once attained a first rank among contemporary editors. Many persons who were unconcerned about the Scottish Church question, or by whom his sentiments on that subject were disapproved, could not withhold an expressed admiration of the singular power with which his views were supported, and of the classic style in which they were conveyed. For some years prior to undertaking the editorship, he had devoted much of his spare time to the preparation of a geological work; and he now, in the columns of his newspaper, in a series of chapters, presented to the public that valuable contribution to geological science, since so well known as his work on "The Old Red Sandstone." To the scientific world, by opening up the fossil treasures of a formation hitherto understood to be peculiarly destitute of organic remains, this publication claimed an especial interest, which was enhanced by the elegance of the diction. His subsequent publications fully sustained his fame. A work on the physical and social aspects of the sister kingdom, entitled "First Impressions of England and its People," was followed by "The Footprints of the Creator," the latter being a powerful reply to the work entitled "Vestiges of the Natural History of Creation." In 1854 he published a most interesting narrative of his early struggles and experiences, with the title, "My Schools and Schoolmasters." "The Testimony of the Rocks," a work on which he bestowed intense labour, and which may be regarded as his masterpiece, was published in March 1857, about three months subsequent to his demise; but all the sheets had undergone his final revision.
For some years his health had been declining; in early manhood he suffered severely from a pulmonary affection, known as the "mason's disease," and he never thoroughly recovered. A singular apprehension of personal danger, inconsistent with the general manliness of his character, induced him for many years never to go abroad without fire-arms. He studied with pertinacious constancy, seldom enjoying the salutary relaxations of society. He complained latterly that his sleep was distracted by unpleasant dreams, while he was otherwise a prey to painful delusions. The eye of affection discovered that the system had been overtaxed; but eminent medical counsel deemed that cessation from literary toil would produce an effectual cure. The case was much more serious; a noble intellect was on the very brink of ruin. On the night of the 24th December 1856, he retired to rest sooner than was his usual, as the physician had prescribed. With redoubled vehemence he had experienced the distractions of disordered reason; he rose in a frenzy from his bed, and, having written a short affectionate letter to his wife, pointed his revolver pistol to his breast. He fired in the region of the heart, and his death must have been instantaneous. The melancholy event took place in his residence of Shrub Mount, Portobello, and his remains now rest in the Grange Cemetery, Edinburgh. As a geologist it is not our province to pronounce his eulogy; he was one of the most elegant and powerful prose-writers of the century, and he has some claims, as the following specimens attest, to a place among the national poets.
