Text: "Keely had shown him (Professor W. Lasselles Scott) a peculiar apparatus, which he called a 'sympathetic negative transmitter.' It had been taken all to pieces for his benefit and put back together again. Imagine a globe in which is a vibrating disk, which Keely calls a 'cladna;' also, a series of tubes which, under certain circumstances, act like small organ pipes. Professor Scott said he could get from Keely no connected account which satisfied his English sense as to what these were but he found that a sensitive ear or hand could appreciate the responsive vibrations from these pipes and the apparatus appeared to be regulated upon something like a definite order or plan. For instance, he discovered that the sympathetic transmitter was sensitive to what is known as B flat, D natural and F and that it was also apparently sensitive to the notes D, F sharp and A. By questioning Keely he found that he regarded the first three notes and their combinations as having a tendency in one direction, which he called a polar force, and the other three notes a tendency in an opposition direction, which he called a depolar force." Public Ledger, Philadelphia, April 16, 1896
