the apotome minor; but one of these is the original comma which is genetically between the two D's; and it occurs here again at the 13th scale, the first of a new circle; it really corresponds to the two D's at the beginning of this first series. Whenever there is more than one comma and the apotome minor between G# and A?, it is because there has been a mistake in counting this one over again; or some other mistake.

In respect of harmony, the natural scale of five notes is like the scale of man's five senses; as the other notes can be compounded so as to form the octave of harmony, so sensation is joined by reflection, and new elements of knowledge come into existence in the process of reasoning. But the knowledge we have in our logical deductions is knowledge on different terms from sensation, which is intuitive; though if the logical process be rightly done, it is knowledge as certainly as the compound chords of the octave scale are harmony, quite as much, and a little more, perhaps, though on more complex terms, as that of the five notes of the natural scale.

"To say that I was surprised at what Mr. Keely has discovered would be saying very little indeed ... It would appear that there are three different spheres in which the laws of motion operate.
1 - The first is the one in which Nature plays her grand fugue on the silent harp of Pendulums. In one period of Nature's grand fugue, as illustrated by pendulums, there are 19 ratios in 25 circles of oscillations ranging over 6 octaves; but all in silence.
2 - In the second sphere the tension of strings and other elastic bodies imbues them with forces operating upon the elastic air, producing vibrations quick enough to awaken sounds for the human ear. Here Nature plays on her tuneful harp the same grand fugue; from which everything in music is derived.
3 - In the third sphere, vibrating things, molecules, atoms, etc. gaseous, liquid, or solid have tensions and forces far beyond the requirements of music, and far above the audible region where musical sounds have been located by the Great Numberer. The multiplication of forces there, and their augmentation derived from sympathy, of which sympathy we have faint illustrations in the region of
