77 (return) [ M. D’Anville has given, in the Memoirs of the Academy for the year 1756, (tom. xxx. p. 198—236,) a plan of Rome on a smaller scale, but far more accurate than that which he had delineated in 1738 for Rollin’s history. Experience had improved his knowledge and instead of Rossi’s topography, he used the new and excellent map of Nolli. Pliny’s old measure of thirteen must be reduced to eight miles. It is easier to alter a text, than to remove hills or buildings. * Note: Compare Gibbon, ch. xi. note 43, and xxxi. 67, and ch. lxxi. “It is quite clear,” observes Sir J. Hobhouse, “that all these measurements differ, (in the first and second it is 21, in the text 12 and 345 paces, in the last 10,) yet it is equally clear that the historian avers that they are all the same.” The present extent, 12 3/4 nearly agrees with the second statement of Gibbon. Sir. J. Hobhouse also observes that the walls were enlarged by Constantine; but there can be no doubt that the circuit has been much changed. Illust. of Ch. Harold, p. 180.—M.] 78 (return) [ In the year 1709, Labat (Voyages en Italie, tom. iii. p. 218) reckoned 138,568 Christian souls, besides 8000 or 10,000 Jews—without souls? In the year 1763, the numbers exceeded 160,000.] 79 (return) [ The accurate eye of Nardini (Roma Antica, l. i. c. viii. p. 31) could distinguish the tumultuarie opere di Belisario.] 80 (return) [ The fissure and leaning in the upper part of the wall, which Procopius observed, (Goth. l. i. c. 13,) is visible to the present hour, (Douat.
