 Here 3^ 4- 41 + 5 J + 7^ + 5^ =VIir, and since 2S = 

 63 + 26, and 3S = 5J +5£ + "JG, ^'^ have 7S + 3^ + 21 = 

 VIII, as before. Also, 7I + • 2d + AJ = VIII, and since 

 2L = 2I + 2d, and 5L= iOd + 5^, we have 7L + 3i = 

 Vlil, as before. 



The Cinquanteneufave Scale of 59 Notes, on the Patent 

 Euharmonic Organ invented bv the Rev. Henry Listen, in

 now exhibiting at their house, No. 101, in St. Martin's

Here 71 + 3*+ 13c -i-2''e + 2t+ ii?=VITl, and because 

 5r + 6g + 1 1"S = 3* + I3c + 2:, the above equation be- 

 pomes 12' + 29g + 22S, as in the Table of Intervals at 

 page 276 of vol. xxxvii ; and also, since 7S = 7C + 2le + 

 14S. 3 = 3ir + 90 — SS, and 2 ■ s= 4c + 2g + ^t, we 

 have 7S + 3 4 2 = VITI, as above. In the third, line, 

 the number of schismas or 2s, answerjng (in my Notation)
