IN the carrying out of some street repairs at Bonn, a portion of a Roman drain or watercourse was lately laid bare at a depth of about 5 ft. below the present surface. It seems to have come from a neighbouring encampment, is about 20 in. wide, and 30 in. deep, and is constructed and covered with heavy tufa blocks, well capable of sustaining the wear of centuries. Many of those blocks were nearly 5 ft. long by 29 in. thick. An original charter of the German Emperor Henry II., dated 25th February, 1015, which has long been given up as lost, has just been discovered during an examination of archives of the collegiate church at Bonn, which was formerly attached to a convent of nuns. The charter is on a single sheet of parchment, very well preserved, measuring 50 by 62½ centimetres (20 in. by 24½ in.), and contains a grant to the church of an estate near Königswinter, belonging to the Emperor. THE tercentary of the death of William the Silent was celebrated in July at Delft, in Holland, by a solemn service in the church. The Prince’s tomb was magnificently decorated with funeral wreaths, including one in silver offered by a deputation of Freemasons. The church was filled by a numerous congregation, all the Ministers and the principal civil and military authorities being present. Professor Van Vries, of Leyden, delivered an address, reviewing in eloquent terms the memorable work accomplished by the founder of Dutch independence. The whole ceremony made a profound impression upon the assembly. At its conclusion the exhibition was opened, at Prinsenhof, the house in which William was assassinated by Balthasar Gerard, of relics of the Prince and a number of objects illustrating his life and works. THE _Athenæum_ says that the death of Mr. Archibald Fraser, of Abertarff, is bringing memories of Jacobite times before the public. Only the other day the history of the Lovat family was to some extent before the Court of Session in connection with the succession to the estate of Abertarff, which was bequeathed to the late Mr. Fraser by his grandfather, a son of the notorious Lord Lovat, with an ultimate entail “in favour of the person who shall be able to prove himself to be the chief of the clan Fraser by legitimate descent from Hugh, first Lord Lovat, and his heirs male.” At the beginning of next month, the Abertarff collection of antiques, pictures, arms, &c., comprising many relics of the rebel lord and of the old family of Lovat, will be sold in Inverness by public auction.
