15. For the manners of the Moors see Procopius (de Bell.
Vandal. 1. ii. c. 6, p. 249 [tom. i. p. 434, ed. Bonn]); for
their figure and complexion, M. de Buffon (Histoire
Naturelle, tom. iii. p. 430). Procopius says in general that
the Moors had joined the Vandals before the death of
Valentinian (de Bell. Vandal. 1. i. c. 5, p. 190 [tom. i. p.
334, ed. Bonn]); and it is probable that the independent
tribes did not embrace any uniform system of policy.
