A Scotch divine, brother of Ebenezer, with whom he co-operated in founding the Secession Church; his sermons and religious poems, called "Gospel Sonnets," were widely read; one of the first of the Scotch seceders, strange to contemplate, "a long, soft, poke-shaped face, with busy anxious black eyes, looking as if he could not help it; and then such a character and form of human existence, conscience living to the finger ends of him, in a strange, venerable, though highly questionable manner ... his formulas casing him all round like the shell of a beetle"; his fame rests chiefly on his "Gospel Sonnets," much appreciated at one time (1685-1752).
