"Within the last twenty years," observes Mr. Montagu, "there have been published some of the very best works that have ever appeared, connected with the subject of heraldry, and its kindred science, genealogy." I much regret my inability to do justice to living and to recently deceased authors in this department of literary effort. In this book-teeming age it would be laborious merely to name all the persons who have written on the subject within the last few years. It will suffice for my purpose to mention some of those who stand _præ cæteris_, either in the intrinsic merit or the magnitude of their productions. SIR HARRIS NICOLAS has rendered essential service to the heraldric student by the publication of several rolls of arms of early date and unquestionable authenticity; namely, those of temp. Henry III, Edw. I (Carlaverok), Edw. II, and Edw. III; and a splendid 'History of the Orders of Knighthood of the British Empire,' in four 4to volumes. The late G. F. BELTZ, Esq., Lancaster Herald, a gentleman of extensive antiquarian research, published an interesting work, entitled 'Memorials of the Order of the Garter.' THOMAS WILLEMENT, Esq. who combines with the research of the antiquary the skill of the artist, has produced, 'Regal Heraldry,' 'Heraldic Notices of Canterbury Cathedral,' and some additional rolls of arms, viz. temp. Rich. II and Hen. VIII. Mr. MONTAGU'S 'Guide to the Study of Heraldry,' evinces a profound knowledge of the subject, and is elegantly written. In addition to these works of general reference, several volumes of great local interest have appeared, particularly several county visitations; among which may be noticed the Visitations of Durham, 1575 and 1615; the former edited by N. J. Philipson, Esq., F.S.A., and the latter by Sir Cuthbert Sharp and J. B. Taylor, Esq.; and Middlesex, 1663, printed at the expense of Sir Thomas Phillipps, Bart. Sir Thomas has also printed, at his own press at Middle Hill, those of Wiltshire, 1623; Somersetshire, 1623; and Cambridgeshire, 1619.
