an Irish Presbyterian divine. In 1728 he published a volume of sermons, which show the influence of Francis Hutcheson. Duchal's studies were classical and philosophical rather than biblical. Late in life he returned to the study of Hebrew, to test the positions of the Hutchinsonian system, in which he found nothing congenial to his ideas. Duchal was an indefatigable writer of sermons: discourses in sets, like courses of lectures. A series devoted to 'presumptive arguments' for Christianity gained him when published (1753) the degree of D.D. from Glasgow.
