I have chosen the dates covered by the title of this paper for two reasons which seem to me to be cogent. The earlier History of the British Customs has been dealt with already in considerable detail by Dr. Hall himself in his authoritative work on the subject, but he will be the first to admit that in his work the later developments are hardly more than touched upon and in addition there is the important work of Professor N. S. B. Gras on the subject, which, though some of his conclusions may be re-considered, yet contains a fund of information, and from these and the State Papers it may be possible at some future date to solve the remaining problems on this aspect of the Revenue.
