In his great History of the Huns, M. de Guignes has most amply treated of Zingis Khan and his successors. See tom. iii. l. xv. - xix., and in the collateral articles of the Seljukians of Roum, tom. ii. l. xi., the Carizmians, l. xiv., and the Mamalukes, tom. iv. l. xxi.; consult likewise the tables of the 1st volume. He is ever learned and accurate; yet I am only indebted to him for a general view, and some passages of Abulfeda, which are still latent in the Arabic text.
