An instance of the use of the 'Portrait' book-plate in England during the last century is afforded by that of 'Jacobus Gibbs, Architectus, 1736,' which is found in the architectural books bequeathed by the possessor to the Radcliffe Library at Oxford, a building which he designed. James Gibbs was born at Aberdeen in 1674, but came south early in his career, and Londoners may see examples of his work in the churches of St. Martin-in-the-Fields and St. Mary le Strand. He also built the Senate House at Cambridge. He died in 1754. On his book-plate, which is oblong in shape and might well form the head-piece to a preface, the portrait appears in a medallion, surrounded by shell and scroll-work. The engraver, who signs his initials B. B., was Bernard Baron, a Frenchman, who came to England in 1736 and engraved Hogarth's portrait of Gibbs. The resuscitator of 'Portrait' book-plates in England in recent times was the late Mr. Thoms. That veteran antiquary tells, in a letter to the _Athenæum_, how he came to use, as a book-plate, a photograph of himself taken by Dr. Diamond in the very early days of photography. Beneath this he placed an inscription setting forth that the volume in which it was fastened was for the use of himself and his friends--a repetition of the sentiment on one of the Pirckheimer book-plates, 'Sibi et amicis.' We do not, of course, know how far Pirckheimer meant what he said; but we do know, any of us who ever asked the loan of a volume from Mr. Thoms, that the sentiment was by him really meant. No worthy book-borrower ever met with refusal from that ever courteous literary enthusiast. After considering 'Portrait' book-plates, the collector may turn his attention to the study of the book-plates that have belonged to interesting men. I have spoken of many of these in reaching this point in my volume, but to the names already mentioned may be added some more: Charles, Earl of Dorset and Middlesex, who, as Lord Buckhurst, was a prominent figure at the dull court of Dutch William, saved Dryden from ruin and introduced Mat Prior to society. Then there is Robert Harley--great minister, great statesman, and underminer of the Whig power; founder of the collection of books and manuscripts which now bears his name. The inscription on his book-plate reads: 'Robert Harley of Brampton Castle in the county of Hereford, Esq^{re}'; it is found in two sizes--one for folio volumes, and another for those of smaller size. Its date may be fixed at the very close of the seventeenth century.
