Tops, (Romance of Science: Spinning Tops, by Professor John Perry,
M. E., D.Sc., F. R. S., 1890, pp. 107-110, 12-13, cited by O'Neil,
_op. cit._, p. 540.) shows how a spinning gyrostat whose spinning
axis is compelled by the experimenter into a horizontal plane is
then constrained by the earth's motion alone to direct its spinning
axis due north and south and so to indicate mathematically the lie
of the true meridian of its spot. If the spinning gyrostat be next
shut off from all other motion except a vertical one in the plane of
this meridian, its spinning axis will point its north end up to, and
continue to point truly up to, the celestial pole." Then, adds
Professor Perry, in terms strangely suitable to my purposes: "It is
with a curious mixture of feelings that one first recognizes the
fact that all rotating bodies, fly-wheels of steam-engines and the
like, are always tending to turn themselves towards the Polestar;
gently and vainly tugging at their foundations, all the time they
are in motion, to get round towards the object of their adoration."
