N. B. The ten Ts to the quints shew that all the quints are TUNED; 

 except the two quints, B, G flat ; and E flat, B flat, marked thus • — — 



The three Ts to the third* shew that ALL the three successive thirds in 

 the C column arc TUNED. 



Anil the two Rs to the quints, and the nine Us to the tliinh, sluw that 

 all the other quints and thirds RESULT from the tuntd intervals.
