We have three copies of these hostile epistles in the Institutions (p. 147), in Sherefeddin (l. v. c. 14), and in Arabshah (tom. ii. c. 19 p. 183 - 201); which agree with each other in the spirit and substance rather than in the style. It is probable, that they have been translated, with various latitude, from the Turkish original into the Arabic and Persian tongues.
