Keely
Mr. Keely gives a few introductory words concerning the necessary graduating of his instruments, for effecting conditions necessary to ensure perfect sympathetic transmission which serve to show the difficulties... attendant upon getting his machines under control and equate the differentiation in molecular masses, requiring greater skill than in researching the force of a sunbeam. He writes: "The differentiation in the molecular metallic masses, or grouping, is brought about in their manipulations in manufacturing them for commercial uses; in the forging of a piece of metal, the drawing of a length of wire, and in casting a molten mass of any form. [Snell Manuscript - The Book, GRADUATION OF MACHINES, page 5]
"He [Keely] has invented instruments which demonstrate in many variations the colours of sound, registering the number of necessary vibrations to produce each variation. The transmissive sympathetic chord of B flat, third octave, when passing into inaudibility, would induce billions of billions of vibrations, represented by sound colour on a screen illuminated from a solar ray." [Bloomfield-Moore] [3rd octave]
