O'Reilly and d'Albe — On a Pandean Pipe. 513 



He also shows that the migrations have been far more extended 

 and frequent amongst those races than would at first seem likely ; and 

 summing up his conclusions as to the sources of the Polynesian races, 

 he says (p. 924) : — "II est certain que I'ensemhle de faits, langues, 

 ressemblances ethniques, moeurs, et traditions designent les terres 

 occidentales, voisines del'Asie comme le principal lieu d'origine des 

 peuples Polynesiens ; c'est en sens inverse du mouvement general 

 des eaux ou des airs que s'est fait le mouvement des nations." 



He further gives the conclusions arrived as to the very remote 

 period at which the principal migration took place : — " A une epoque 

 deji fort lointaine, alors que les indigenes des- terres voisines del'Asie, 

 n'avaient pas encore subi I'influence hindoue et que la civilisation 

 malaise ne s'etait pas constitute, refoulant les habitants primitifs dans 

 I'interieur des lies. Aucune trace de Sanscrit ne se trouve dans les 

 langues Polynesiennes ; les insulaires de I'Oceanie Orientale descendent 

 done d'aieux qui n'ont pas connu les religions hindoues — p. 926, ces 

 temps sent tres eloignes de nous." 



If it be admitted as possible that traces of this very remote origin 

 be still existing in the manners and customs of the Polynesians, their 

 music would be likely to be one of them, so that the object of the 

 present Paper would gather interest from that side also. 



Mr. Foumier d'Albe's determinations which follow, speak for 

 themselves; for the general reader his conclusion is that the notes 

 extend over three octaves, with five notes on each octave, the rough 

 sequence being C, D sharp, F sharp, A. 



The Tanna Syeikx. 



This instrument consist of a graduated series of fifteen pipes, 

 lashed together like the ancient Pandean pipes. The pitches of the 

 notes given by these pipes were determined — 



(1) By calculation, dividing the velocity of sound in air at 16° C. 

 by four times the sum of the length and the radius. 



(2) By experiment, comparing one of the pipes (the fifth) with a 

 standard tuning-fork, and comparing the length of a stretched string 

 in unison with this fundamental pipe with the lengths corresponding 

 to the other pipes. Four strings of different diameters and densities 

 were used for these measurements. 



The results are given in the following Table. The lengths are 

 given in centimetres, and the pitches in complete vibrations per 

 second.
