MR. THOMAS W. LIDDERDALE, for over thirty years an officer of the British Museum, and latterly a first-class assistant in the Printed Book Department, died suddenly in the Strand, on September 4, when returning home from his ordinary duties. Mr. Lidderdale was a scholar of rare attainments in Scandinavian literature, and particularly in the more contracted sphere of Icelandic bibliography. THE death is recorded of M. STANISLAS GUYARD, a distinguished Semitic scholar. At the end of last year he was appointed Professor of Arabic at the Collége de France, in succession to the late M. Defrémery. His publications on the language and literature of the Arabs have been numerous; but to English readers it will be enough to point out his great article on “The Eastern Caliphate,” in the sixteenth volume of the new edition of the “Encyclopædia Britannica.” His interests, says the _Academy_, were by no means confined to Arabic. He had recently taken up with ardour the study of Assyrian. He shares with Professor Sayce the credit of finding the interpretation of the mysterious inscriptions of Van; and, to the astonishment of English students, he declared himself a convert to the theory of M. Halévy--that the so-called “Accadian” of the cuneiform tablets is no language at all, but only a secret mode of writing Assyrian. M. Guyard was assistant secretary and librarian of the Société Asiatique, and one of the four editors of the _Revue Critique_. He died by his own hand at Paris, in his forty-first year. MR. E. A. ROY, Assistant-Keeper of the Printed Books in the Library of the British Museum, died on August 14, aged 64. Mr. Roy had been employed at the British Museum since 1841, and was appointed by Mr. Winter Jones, the Principal Librarian, in 1871, to the post of Assistant-Keeper of Printed Books, a post then specially created for an officer charged with the superintendence and acceleration of the progress of the catalogue of books and final revision of the titles. MR. HENRY G. BOHN, F.S.A., the oldest bookseller and publisher, and himself the author of sundry “Handbooks” of London, of Games, &c., died at the age of 88, at Twickenham, on the 22nd August. He first brought his name into notice by his “Guinea Catalogue of old English Books,” which he printed in 1841; to our readers he will be best known by his “Historical” and “Antiquarian” Libraries. THE death is announced of Mr. JAMES NAPIER, of Stonehaven, author of two local historical works, entitled “Stonehaven and its Historical Associations,” and “The Honours of Scotland,” the latter being an account of the preservation of the Scottish regalia when Dunottar Castle was besieged by the army of the Commonwealth in 1651.
