If the limiting radius of solar retardation (L 36.4, see ante, p. 415) be 
regarded as also a limit of explosive oscillation, and if radii terminating 
in the cardinal points of the explosive excursion (4, 4, 3, 4, 4, 2, §) be 
employed for determining a parabolic series, the mean distances of 
Venus, Earth, and Jupiter, will be represented by succeeding abscissas 
of the same series, as in Table IIT.
