After having spent nearly fifteen years in the profession of a stone-mason, Mr. Miller was promoted to a position more suited to his genius. When a bank was established in his native town of Cromarty, he received the appointment of accountant, and he was thus employed, for five years, in keeping ledgers and discounting bills. When the contest in the Church of Scotland had come to a close, by the decision of the House of Lords in the Auchterurder Case, Mr. Miller’s celebrated letter to Lord Brougham attracted the particular attention of the party which was about to leave the Establishment, and he was selected as the most competent person to conduct the _Witness_ newspaper, the principal metropolitan organ of the Free Church. The great success which this journal has met with is owing, doubtless, to the fine articles, political, ecclesiastical, and geological, which Mr. Miller has written for it. In the few leisure hours which so engrossing an occupation has allowed him to enjoy, he has devoted himself to the ardent prosecution of scientific inquiries; and we trust the time is not far distant when the liberality of his country, to which he has done so much honor, will allow him to give his whole time to the prosecution of science. Geologists of high character had believed that the Old Red Sandstone was defective in organic remains; and it was not till after ten years’ acquaintance with it that Mr. Miller discovered it to be _richly fossiliferous_. The labors of other ten years were required to assign to its fossils their exact place in the scale.
