From the
fourth to the fifteenth octave, 16 to 32,768 per second, we get sound.
The qualities of the 16th to the 24th are--or have been, until I
investigated--quite unknown. The 25th to the 35th, 33, 554, 432 to 34,
859, 738, 868 vibrations per second, give us electricity. Thence to
the 45th, again unknown.
"The 4th to the 48th give us heat. The 49th gives light The 50th,
chemical rays, vibrating 1, 125, 899, 906, 842, 624 per second. The
51st to the 57th have never been touched by anyone save myself. The
X-ray group extends from the 58th to the 61st octave. The 62d, with 4,
611, 686, 427, 889, 904 vibrations per second, is a field where only
I have worked. And beyond these, no doubt, other octaves extend with
infinite possibilities.
"You will note, _monsieur_," he continued, while the dun penumbra
still more and more withdrew him from Leclair's sight, "that great
lacunae exist in the scale of vibratory phenomena. Some of the
so-called lower animals take cognizance of vibrations that mean
nothing to us. Insects hear notes far above our dull ears. Ants are
susceptible to lights and colors unseen to our limited eyes. The
emperor-moth calls its mate--so says Fabre--by means of olfactory
vibrations totally uncomprehended by us.
