Mr. Farey’s Letter on musical Intervals, &c. 1 
4 times the first expression, or 2448 5+448f+212m, and 
add it to the third expfession, making 38692+ 76f+ 335m, 
and then deduct this last, from the multiple first found in 
this case, and the remainder is 11>+m, the notation of c. 
Further examples may appear unnecessary here ; yet it 
will be proper to add, that if the calculations by this rule 
are gone through, which are indicated above, by the ratios 
answering to =, to f, and to m, respectively, they only, will 
be found to result, respectively ; or, the truth of the whole 
may be demonstrated in various other ways, as is shewn in 
the “ Edinburgh Encyclopeedia,” vol. IX. p. 275.
