.".so Mr. A. J. Ellis. Tonometrical Observations on [Nov. 20, 



4. First Chime of Small Gongs or Yan-lo, a set of 10 small gongs 

 about the size and shape of cheese-plates, arranged with I at the top, 

 II, III, IV in the first row, from left to right behind, where they 

 were struck with a wooden hammer, and then V, VI, VII in the 

 second, and VIII, IX, X in the third row, all hung in a square 

 wooden frame. The Chinese musician played in the order of pitch, 

 omitting IX and I.

Here again there is no approach to a Fourth of 498 cents, or a 

 Fifth of 702 cents. 



5. Second Chime of Small Oongs or Yan-lo, in the S. K. Mns., 

 " Engel," p. 193, who describes the scale wrongly. Although the 

 instrument is of the same appearance as the last, the scale was 

 entirely different, and the compass did not reach 750 cents. We 

 seemed to make out three possible scales which are annexed, but we 

 have no means of knowing if they were designed. One extends to a 

 sharp and another to a flat Fifth, whilst the third reaches an exact 

 Fourth. The gongs are numbered as in No. 4.

The last is therefore like the first tetrachord in the bagpipe scale, 

 dividing the Fourth into a Tone and two Three-quartertones. There 

 are, however, several curious intervals. 



VI 19 VIII nearly a comma of 22 cents. 

 Ill 26 IV nearly of a major Tone of 204 cents. 

 I 52 II exactly J of a major Tone of 204 cents. 



II 188 III and III 178 IV are both nearly the minor Tone, of 182 

 cents. 



I 240 III is an exact pentatone, or \ Octave, as in the tempered 



Javese Salendro scale. 



II 385 VIII is an excellent major Third of 386 cents. 



I 586 V and I 589 IX are both nearly the Zaid of 588 cents, 

 on the second string of the Arabic lute.
