The ill-health which has so long postponed the completion and appearance of this work is responsible for some shortcomings of which no one is more conscious than myself. It has been necessary to correct the proof-sheets at a distance from works of reference, and indeed from England, while the length of time that has elapsed since the bulk of the work was composed is such that two or three new books bearing upon the same period have appeared in the mean while. Of these I would specially mention Mr. Howlett's contributions to the Rolls Series, and Miss Norgate's well-known _England under the Angevin Kings_. Mr. Howlett's knowledge of the period, and especially of its MS. authorities, is of a quite exceptional character, while Miss Norgate's useful and painstaking work, which enjoys the advantage of a style that one cannot hope to rival, is a most welcome addition to our historical literature. To Dr. Stubbs, also, we are indebted for a new edition of William of Malmesbury. As I had employed for that chronicler and for the _Gesta Stephani_ the English Historical Society's editions, my references are made to them, except where they are specially assigned to those editions by Dr. Stubbs and Mr. Howlett which have since appeared. A few points of detail should, perhaps, be mentioned. The text of transcripts has been scrupulously preserved, even where it seemed corrupt; and all my extensions as to which any possible question could arise are enclosed in square brackets. The so-called "new style" has been adhered to throughout: that is to say, the dates given are those of the true historical year, irrespective of the wholly artificial reckoning from March 25. The form "fitz," denounced by purists, has been retained as a necessary convention, the admirable _Calendar of Patent Rolls_, now in course of publication, having demonstrated the impossibility of devising a satisfactory substitute. As to the spelling of Christian names, no attempt has been made to produce that pedantic uniformity which, in the twelfth century, was unknown. It is hoped that the index may be found serviceable and complete. The allusions to "the lost volume of the Great Coucher" (of the duchy of Lancaster) are based on references to that compilation by seventeenth-century transcribers, which cannot be identified in the volumes now preserved. It is to be feared that the volume most in request among antiquaries may, in those days, have been "lent out" (cf. p. 183), with the usual result. I am anxious to call attention to its existence in the hope of its ultimate recovery. There remains the pleasant task of tendering my thanks to Mr. Hubert Hall, of H.M.'s Public Record Office, and Mr. F. Bickley, of the MS. Department, British Museum, for their invariable courtesy and assistance in the course of my researches. To Mr. Douglass Round I am indebted for several useful suggestions, and for much valuable help in passing these pages through the press.
