The Bodleian binding is in very fair condition, but the British Museum one is, unfortunately, in a very dilapidated state. Luckily, however, it has not been restored, so what is left can be safely examined and relied upon. English royal bindings, of old date especially, now rarely come into the open market, but in the latter part of last year a most interesting specimen that belonged to Henry VIII. was purchased by the British Museum. It is a manuscript on the science of geometry, written on paper and dedicated to the king. It is bound in white leather, and has many signs that it is the work of Thomas Berthelet. There is an outer border of blind and gold lines, with solid arabesques at the outer corners, and stars in the inner corners. The centre of each board bears a geometrical design of triangles and lines filled in with stars and dots. In the upper part of each board is a cartouche bearing the words "VIVAT REX," and at the lower part a similar cartouche with the word "GEOMETRIA," followed by an arabesque ornament. Written in gold on the white edges are the words "REX IN ÆTERNUM VIVE NEEZ." There is no book of Berthelet's, except this one, on which the decoration has any reference to the contents of the volume. It is indeed probable that this is actually one of the first books in which there has been any endeavour to make the outside decoration agree with the subject-matter inside. The word "Nez," or "Neez," which usually occurs after the "Rex in Æternum Vive" so frequently painted on the edges of Henry VIII.'s books, has been a puzzle for some time. Mr. E. L. Scott of the British Museum suggests that it may stand for the first letters of the words "[Greek: Nabouchodonosôr esaei zêthi]," as the king to whom the words are addressed in the Book of Daniel is Nebuchadnezzar. This explanation I have already given in _Bibliographica_, part viii.
