a different power of found, the quality of the har- 
mony will become manifeft, from the fuccefhon of 
the founds in order (25). 
In this paffage, it is to be obferved, that the term 
c-jjjKgior, a Sign, Signifies a muSical character, fuch as 
the antients ufed to write over the words of a fong, 
to exprefs the air, or tune ; and that each of thefe 
characters reprefented not a found of the fyftem, fub- 
jeCt to tranfpofttion, but, like the notes of our gamut, 
a found of a certain pitch, or at lead liable to very 
fmall variations only, from the generic differences. 
The term, therefore, is properly ufed here by Arifti- 
des, in opposition to <p£royy@->, a found of the fyftem, 
whofe pitch depended on the mode in which it was 
employed. As to the expreflion, quality of the har- 
mony, it evidently refpeCts the fpecies of diapafon ; 
fo that the author plainly means to tell us, that if we 
begin a diapafon always with the fame note, the 
fucceftion of its founds, that is, the manner in which 
it is divided, will determine the fpecies: and fo far 
he fpeaks to our purpofe. But this point will re- 
ceive farther proof, from what we Shall fay upon the 
next. 
4. The fourth point being the natural refult of the 
combination of the two doCtrines, carries a fort of 
conviction with it ; and the Stronger, as not only the 
feven modes, but the whole fifteen, affift the proof, 
as will appear, on examining the table I have given 
of them : for there the founds lying between the
