V. SIAM. 



The Ranat in South Kensington Museum is a wood harmonicon 

 with 19 bars, scale wrongly described in " Engel," p. 316. Bar XIII* 

 was of a different kind of wood, and had evidently been inserted as- a 

 substitute for the Octave of VI, but was too sharp.

This is inserted out of geographical position, because it is a solitary 

 example from Africa, and resembles those immediately preceding 

 in character. A Balafong in South Kensington Museum, No. 1080,

VII. JAVA. 



The scales were observed from the instruments of the Javese 

 Gamelang or band, at the Aquarium, in November, 1882, and formed 

 the commencement of these investigations. We were materially 

 assisted by work done on the same instruments (but without deter- 

 mining pitch) by Mr. W. Stephen Mitchell, M.A., of Gonville and 

 Cains College, Cambridge, and by determinations with the monochoni 

 of similar instruments in Holland by Professor J. P. N. Land (who
