It mud be here obferved, that thefe fpecies, as 
they ftand in the fyftem, are, with refpedt to acute- 
nefs and gravity, in the inverted order of the feven 
modes, as fettled by the harmonic do&rine, which 
will account for the miftake, which Dr. Gregory (as 
was fliewn above) and others have fallen into, in 
imagining the antients did not agree in their accounts 
of the modes ; fince it is plain thefe writers did not 
obferve, that, in the one cafe, the modes were fpoken.

and in the other, with refpedt to the pofition of the. 
feven fpecies within the fyftem. 
Thefe fpecies may alfo be more readily fliewn, by 
examples out of theGuidonian fcale, where, keeping

But as well this, as the former way of fhewing 
them, we are to underftand only as exemplifications 
of the fucceflion of the intervals, and not as an align- 
ment of the pitch for each, which was to depend on 
*hat of the fyftem, out of which they are exemplified ;
