In the above Tables, where two consonances are linked 

 together, only one of these can be tuned or taken on a 

 douzeave Instrument, and they are only inserted here, for 

 explaining the effects of different modes of tuning these 

 notes, which so frequently lequire to he changed, in the 

 taking of chords and in modulating. The 2nds in the first 

 line in the last Table, are not in reality Wolves, because I 

 is the proper value of a sharp or a flat, in Tempered Sy- 

 stems, but are inserted to show, that they differ from L the 

 minor Second.

 Here the Octave in perfect Intervals, consists of SS + 

 33 + 4?) 4- 2£, as in the second line, and since y + £ = S, 

 this is equivalent to 7S + 3'. + 2/', as in the douzeave 

 scale above. In the third line the elements of a regularly 

 Tempered Scale on this Instrument are shown, the octave 

 consisting of 5L + 7I -f 2d; and since the minor Limnia
