Rh around the exchequer and transacting the business of the realm—all these are pictures that must find a place in any general work on the middle ages.

It remains for me to say a word of acknowledgment to those who have generously helped me in my present task. One of them, Dr, S. Lowenfeld, can, alas! no longer hear the words of thanks of his disciple. There seldom has been a man who took such unselfish interest in all his pupils. My thanks are also due to Professor Emerton, of Harvard University, who first roused in me an interest in historical studies, and in whose seminary the idea of a book like the present was first broached.

In the matter of actual assistance with the work in hand. I am bounden to no one so deeply as to Dr. F. Liebermann, of Berlin, who allowed me to presume upon his amiability to quite an unreasonable extent. He has read with me. word for word, my whole manuscript of the Dialogue concerning the Exchequer. E. F. H., March 18th, 1892.
