David M. Moir

Moir, David Macbeth, was born at Musselburgh, Jan. 5, 1798. After attending the medical classes in the University of Edinburgh, he settled down as a doctor in his native place. In June, 1851, he went to Dumfries to recruit, but died there, July 6, and was buried at Inveresk, Musselburgh, July 10, 1851. His poems, selected and edited, with a memoir, by Thomas Aird, were published in 1852, in 2 vols., as The Poetical Works of David Macbeth Moir. He marked his graver contributions to Blackwood's Magazine with the signature "Delta" or Δ and in the number for August, 1832, there appeared "Devotional Melodies by Delta." These were three in number:—
1. Return, once more return, O wanderer.
2. O who is like the Mighty One.
3. How pleasant is the opening year.
and seem to have been the only hymns suited for public worship that he ever wrote. [Rev. James Mearns, M.A.]
