Evans for help and advice as to the choice of a text, and as to procedure with regard to publication ; and to Mr. Ernest Hughes, late of Jesus College, and now Lecturer in History at the University College of South Wales, to whom I am indebted for many suggestions whilst the Introduction and Glossary were still in proof. Finally, I have to thank the Delegates of the Clarendon Press for undertaking the publication of this work, and also the staff for the kindness and the efficiency which have so much lightened my labours.
