[Footnote 39: Arrian, in the second century, remarks (in
Periplo Maris Erythraei, p. 12) the partial or total
difference of the dialects of the Arabs. Their language and
letters are copiously treated by Pocock, (Specimen, p. 150 -
154,) Casiri, (Bibliot. Hispano-Arabica, tom. i. p. 1, 83,
292, tom. ii. p. 25, &c.,) and Niebuhr, (Description de
l'Arabie, p. 72 - 36) I pass slightly; I am not fond of
repeating words like a parrot.]
