Lipsius (tom. iii. p. 423, de Magnitud. Romana, 1. iii. c. 3) and Isaac Vossius (Observat. Var. p. 26-34) have indulged strange dreams, of four, or eight, or fourteen millions in Rome. Mr. Hume (Essays, vol. i. p. 450 457), with admirable good sense and scepticism, betrays some secret disposition to extenuate the populousness of ancient times.
