more exact ratios to the oxygen than to the hydrogen unit, appears to have

428. Universal Rotation. 
The hypothesis that every material particle is endowed with rotation, by 
which it represents a definite amount of living force, has often been 
broached. Its probability is strengthened by the magnetic theories* of 
Arago, Ampére, Barlow, Lecount, Challis, Babbage, Herschel, Christie, 
Maxwell, Imray, Forbes and others ; by my own investigations confirma- 
tory of the hypothesis that ‘ there can be no weight without some degree 
of momentum ;’’+ by the connection of magnetism with rotation in a 
magnetic field through Laplace’s principle of periodicity (note 333) ; and by 
the evidences which are furnished, by notes 418 and 419, of interstellar 
ethereal rotation, producing nodes which are determined by stellar 
moduli of light. According to this hypothesis no material particle can be 
wholly divested of energy, and no particle can ever acquire energy 
enough to free it from the equilibrating tendencies which spring from the 
law of equal action and reaction. 
424, Nascent Nebular Rotation. 
The beginning of the transfer of rotation from ethereal particles to cos- 
mical masses, is illustrated by the equivalence of ratios between masses 
and rupturing distances, in the two ruling globes of the solar system. 
Taking Bessel’s estimate of the mass-ratio of Sun to Jupiter (1047.879), 
the vector-radii of the two bodies, when in static equilibrium with regard 
to their common centre of gravity, should be in the same ratio. The pro- 
jectile energy, which changed the static into an oscillatory dynamic equi- 
librium, has produced a secular eccentricity, according to Stockwell, of 
.0608274, the secular perihelion being, therefore, .9391726 of Jupiter’s mean 
radius vector, Dividing the static ratio of vector radii, 1047.879, by 
.9391726, we get 1115.7469 x Sun’s semi-diameter for Jupiter’s mean radius 
vector. Dividing this value by 5.202798, we get 214.4513 for Harth’s mean 
radius vector, which represents a mean solar apparent semi-diameter of 
961//.8254. The British Nautical Almanac estimate is 961//.83.

Laplace’s principle of periodicity, and incipient ‘‘subsidence,’’ according 
to Herschel’s modification of the nebular hypothesis, are both exemplified 
in the equation; 
(1— ¢) sts = Vg, 7% 
in which ¢ == Jupiter’s secular eccentricity ; J, gs == gravitating accelera- 
tion at the equatorial surface of Sun and Jupiter, respectively ; ¢, == time
