A portentous though frequent, mistake has been the confounding, from a slight similitude of name, the Cyrene of the Greeks and the Cairoan of the Arabs, two cities which are separated by an interval of a thousand miles along the sea-coast. The great Thuanus has not escaped this fault, the less excusable as it is connected with a formal and elaborate description of Africa (Historiar. l. vii. c 2, in tom. i. p. 240, edit. Buckley).
