The third part of Mr. H. H. Howorth's History of
the Mongols (Longmans) is devoted to "The Mongols of Persia." It is an ill return for the vast labour expended upon this work, for the reviewer to pass it over in a few lines. But who is sufficient for the task of estimating work of this kind? The author has collected materials for his History with an industry that is beyond all praise. A mere inspection of the references given in the foot-notes will impress any person at all acquainted with historical work, with a notion of the energy with which Mr. Howorth devotes himself to his task. Not only Western writers on Oriental subjects, but the original authorities have been laid under contribution. The volume includes a period of about a century and a half, from the early part of the thirteenth century till late in the fourteenth. We wish Mr. Howorth health and strength for the completion of a work of great value.
