Note 41 — XXIII The Beauty of Landscape

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.
