The table includes about seventy known octaves ranging from 20 X units to 20,000 meters. The octaves are plotted on a logarithmic scale 1 X arbitrarily chosen as the end of the first octave. The wave-lengths and frequencies of such radiations as are characteristic of known phenomena as well as those which limit certain known regions, arc charted with notations of interest made opposite.
