Savary, Lettres sur l'Egypte tom. ii. lettre xv. p. 189 - 208. I much question the authenticity of this copy; yet it is true, that Sultan Selim concluded a treaty with the Circassians or Mamalukes of Egypt, and left them in possession of arms, riches, and power. See a new Abrege de l'Histoire Ottomane, composed in Egypt, and translated by M. Digeon (tom. i. p. 55 - 58, Paris, 1781), a curious, authentic, and national history.
