Having said all the above about multiple octave counting we must admit when counting up four octaves then immediately counting back down that this makes no sense. And it does not make sense because this is not a linear and straight line progression as one would, say, count keys on a piano keyboard from left to right. Russell is pointing out with this pattern the concept that energy accumulates from the seeming empty Vacuum of Space at 0 potential and condenses to a sphere at 4++, point of Voiding two seeming opposite states, syntropic and entropic which he sometimes calls Father and Mother, respectively. See Father-Mother Principle
Within Russell's discussion of octave relationships he maintains the entirety of the Electromagnetic Scale is a vast gamut of ten octaves. Wherein, for instance, Carbon sits at the center position in octave five at the Perfect Fifth location of "G" or 4++. Thus within his system Carbon would correspond to music note "G" at the center of a ten octave gamut. All this is symbollic of course and not standard musical notes as we know and categorize them. However, the Principles that are found in music such as relativity, reciprocity, additive synthesis and many others are as much a part of his philosophy as that of Keely's. More on these music relations can be seen in Music.
