[Footnote 67: This measure was taken by Roger l., after the
conquest of Naples, (A.D. 1139,) which he made the capital
of his new kingdom, (Giannone, Istoria Civile, tom. ii. p.
169.) That city, the third in Christian Europe, is now at
least twelve miles in circumference, (Jul. Caesar. Capaccii
Hist. Neapol. l. i. p. 47,) and contains more inhabitants
(350,000) in a given space, than any other spot in the known
world.]
