VI GENERAL PREFACE time during the ensuing twelve months, any possessor of that volume who will send a stamped and addressed envelope to the Cambridge University Press, Bentley House, 200 Euston Road, London, N.W. i, shall receive, in due course, a free copy of the errata in that volume. Thus, with the help of our critics, we may reasonably hope to put forward these mono- graphs as roughly representing the most accurate information obtainable under present conditions. Our facts being*thus secured, the reader will judge our inferences on their own merits; and something will have been done to dissipate that cloud of suspicion which hangs over too many important chapters in the social and religious history of the Middle Ages.
