This may be the place to notice a fine collection of old trumpets in the possession of Prince Charles of Hohenzollern-Sigmaringen. They were made by Johann Leonard Ehe, in N¸rnberg; Hieronymus Stark, in N¸rnberg, anno 1669; Christopher Frank, Magnus Wolf, Wilhelm Haas, anno 1688. Passing over the Royal Museum of Northern Antiquities at Copenhagen, which contains highly curious specimens of the old Scandinavian brass trumpet called _lure_--especially interesting if compared with the bronze trumpets of mediÊval time excavated from bogs or mosses in Ireland, and now preserved in the Museum of the Royal Irish Academy at Dublin--we now proceed to a cursory survey of the musical antiquities in the museums of London. The British Museum possesses several instruments, or fragments of instruments, of the ancient Egyptians, Greeks, and Romans, and old Celtic trumpets which have been found in Ireland. In the ethnological department of the British Museum are particularly noteworthy:--The specimens of Chinese instruments brought over to England by Mr. Tradescant Lay; those from Siam, obtained by Sir John Bowring; those from Java, obtained by Sir Stamford Raffles; a considerable number of flutes, including nose-flutes, and of trumpets, from Otaheite, Tongataboo, and New Zealand; well-preserved drums from the Polynesian Islands; serpent-headed drums of the natives of New Guinea; Negro instruments from Western Africa, etc. The Museum of the East India House, in London, contains upwards of 120 musical instruments, mostly from Hindustan and Burmah, some of which are very fine, but many are out of repair. An assemblage of curious pipes, trumpets, and drums of the Polynesians, as well as fiddles of the Hottentots and Kafirs in Southern Africa, may be seen in the Museum of the London Missionary Society. Furthermore, the Botanical Museum at Kew possesses several interesting contrivances of this kind, made of peculiar species of wood by Indian tribes in South America. The collection of musical instruments belonging to the South Kensington Museum is now, as far as is known, the most comprehensive in existence. The latest edition of its catalogue, published in the year 1874, describes 353 instruments, of which 246 belong to the Museum, and 107 are on loan. The catalogue contains 143 wood-engravings and six photographs of instruments, and is preceded by an essay on the history of musical instruments. A glance at its comprehensive index will perhaps convey to the reader the impression that it takes cognizance of almost every musical instrument in the world. This is, however, by no means the case. Even an account of all our own instruments in use at the present day would fill a large volume. But, endeavour has been made to render the catalogue as comprehensive as is consistent with its object, and the reader will find in it illustrations and descriptions of most of the instruments mentioned in the present essay.
