A tendency to four-octave intervals, is shown in the different planetary 

 values of mr (Sun -=- planet) which are, approximately as follows : 



Mercury 2 30 X «* Jupiter 2 13 X ! (E)

Earth 2 25 (C) Uranus 2 19 X § (D t ) 



Mars 2 2!l (C) Neptune 2 18 X f (A.) 



The value for Mercury is 3 X 4 octaves higher than that for Neptune ; 

 Venus and Earth, 3X4 octaves higher than that of Jupiter ; Mars, 4 

 octaves higher than Earth ; Uranus, 4 octaves higher than Saturn.
