The corrections under “5. Quantitative applications of the Laws 
to the fundamental facts of Musical Harmony,” can be readily 
applied from the law as given above. Suffice it here to say that 
on the table on page 252 the nearest consonant interval in the 
octave of C, is a Fourth+2 of a semitone; while in the octave 
of C, the nearest consonant interval of two simple sounds has 
contracted to only one tone.
