thanking those to whom this volume owes its

external attractions or internal correctness. My best thanks are due to Mr. E. Burne-Jones for the beautiful design which forms the frontispiece to the book itself, and embodies the ideal of Oriental Tradition. The Duke of Devonshire was good enough to send his copy of the Italian original to the British Museum for comparison, and the Trustees of Dr. Williams' Library gave me facilities for collating with their precious copy of the first edition.
