{t will be seen from Professor Fisher’s Table im p. 32, 
that a very decided majority of organ pieces, in the major 
mode, are setin Gand D: and ano less marked majority of 
those in the menor mode, in A and D; and it is on this 
account that 1 have drawn a black line, to separate’ the 
gainor thirds in the above Table: the Vths are placed in 
the middle line, for more ready comparison with the Ids 
above and the 3ds below ; and the wolves are separated by 
semicolons. 
I beg now to congratulate Professor Fisher on the happy 
result of his ingenuity and labour, in calculating this Dou- 
zeave: viz. as to the very near agreement exhibited above, 
with what I understand to be the present practice of all the 
best Tuners of organs; I mean, as to the exceedingly 
small ‘Temperaments of that very important concord the 
major Third, in the five most important Keys, viz, G, D, 
C, F and A; as to the very moderate temperament of this 
concord, in the Keys Bo and E; and as to the four Iild 
wolves, (which are, alas! inseparable from a Douzeave 
Seale,) falling in those Keys, where all judicious Tuners 
have been used to throw them; and the least of these 
wolves falls in the Key of B, which oftenest occurs. The 
only thing which strikes me as an unlooked-for anomaly as 
to the HIds, is, the ‘'emperament on Eb, being so consider- 
able, as more than half a comma. 
With regard to the fifths, considered with relation both to 
the major and minor modes, in the three important Keys G, 
F and &, the Temperaments are less than in the Mean-Tone 
system (or 2¢2,) now so generally used on the organ: in 
the three other important Keys D, C and Eb, the Temper a-
