[17] Confer.—"The primal One, from which all things are, is everywhere and nowhere. As being the cause of all things, it is everywhere. As being other than all things, it is nowhere.... No predicate of Being can be properly applied to it.... It is greatest of all, not by magnitude, but by potency.... It is to be regarded as infinite, not because of the impossibility of measuring or counting it, but because of the impossibility of comprehending its power. It is perfectly all-sufficing."—"The Neo-Platonists: A Study in the History of Hellenism." By Thomas Whittaker. Cambridge, 1901. Chapter v., pp. 58, 59.

[41] Professor W. W. Campbell, of the Lick Observatory, California, computes the velocity of the Solar System through space at approximately nineteen kilomètres per second (see Lick Observatory Bulletin, No. 195, vol. vi. (1910-1911), p. 123. See also Bulletin No. 196, vol. vi., pp. 125 et seq.). What, in interstellar space, the precise curve described by my finger nail was, especially if to rotation, revolution, and the approach to Hercules, we add nutation, tidal drag, and the precession of the equinoxes, to say nothing of earth tremours, I should much like to know.

[42] All my figures are, of course, rough in the extreme; and I give Professor Campbell the benefit of about fifty miles a minute because he says approximately.
