mg 2s the order of placing the Intermediate with rela- 
tion to the firft and laftot them is,fo the differing diffs 
are conftituted.Of which he notes,that that order accord- 
mg to which we make our Rings of Bells is the moft 
agreeable taall Ears;and this we moft eafily exprefs with 
our Voice^either in rifmg or falling Notes,the half Tones 
being fo properly and Naturally mixt. But he conceives 
a Ring of Bells tuned to Chromatick IniervaLs would 
found very uncouth and unpleafant to moft Ears ; and 
if tuned to the Enharmonick, would be intolerable, and 
the pradice of it would be a violence upon Nature. But 
the Diatonick Intervals being more equal and uniform, 
are alfo more Natural. However thefe Intervals are not 
alJ alike, but are of three kinds, namely, Hemitone 
Major, Tone Minor, and Tone Major, called Degrees, 
Minor, Major, and' Maxim. Each of which has its 
proper place in the Odave, and that is, fuch as com- 
pleats the Harmonick Intervals, whence in Organs and 
Harpficords, where the Notes are fixt, the proper Af- 
cent and Defcent cannot be made but only beginning 
from fome Keys, becaufe the Flats or Half-notes to o- 
ther Keys do not keep a due or fitting Proportion for 
that Cliff. He has given foUr Examples of thefe Scales^ 
pag. 1 5" 5". and explained them in the following Pages. 
He concludes this Difcourfe with a Table, containing 
all the Notes and Intervals , explaining how each of 
thofe in the Diatonick Scale a^e compofed of thofe three 
Degrees, viz. Mtner^ Major^ and Maxim. 
In the Seventh Chapter he treats of Difcords ; that 
is, of fuch as are found in the Scales of our Mufick in 
the Afcent or Defcent in differing Cliffs, where the De- 
grees which are placed right for one Cliff, muft neccfla- 
riiy be unfic for another Cliff, whence the Concords in 
thefe wrong Cliffs are found to have a Comma, aDiefis, 
and fometimes a Hemitone too much or too little: For 
the adjufting of wliich there will arife two other kinds^
