The tones of the second series are all near together ; those of the first are separated 

 by intervals rather less than for a harmonic scale. 



(2.) In the motions of the second type A = 0, and P p (/*) vanishes with /* ; hence ft 

 is an odd number, and 



2) = w. (84) 



If p"i be the value of p corresponding to K",-, we have 



and 



V = 0, w 0, 



v = s " [v/0 - 



and K'\ is given by the table : 



. . . . (85) 



These intervals are nearly fifths.
