mass, its greatest vigour being at the centre of this axis, or 
the general centre of all the accordant momentums of the 
particles, and of the individual attractions of the atoms, if 
the mass is composed of atoms. 
But any motion towards such a centre tends to vibrate 
through it ; any motion transverse to it tends to change 
from a straight to a curved line, this curve arching inward 
if the motion be attractive, outward if it be repulsive. 
Thus around the centre of attraction of such a moving mass 
all accordant motions would bend into curved lines, the 
whole mass tending to rotate around its general centre of 
attraction.* But if its substance was perfectly homogeneous 
in condition this tendency would be equal in all accordant 
directions, and no rotation could result, the resisting impacts 
being exactly balanced. But if — as most probable — it was 
heterogeneous, the impacts would cease to be equal. There 
might readily occur an excess of motion in one direction 
near the centre, the point of strongest attraction. Such a 
motion would have an advantage over all more distant oppo- 
site motions. Its tendency would be to repel the reverse 
motions, and to move around the centre with a radius de- 
pending upon the degree of curvation. There would be a 
new series of accordant motions, yielding a new attractive 
energy upon accordant, and repulsive energy upon discordant 
motions. The original sorting out of directions of motion, 
under the influence of the motion of the mass through 
space, would be followed by a new sorting process under the 
influence of rotation of the internal portion of the mass 
around its centre. The central motion thus inaugurated 
must gradually extend its influence outward through the 
mass. 
This new series of parallel motions set up in the mass 
would not necessarily be around the original axis of mass 
motion, but might be around a new axis of rotation, at 
some angle of accordance with the direction of mass motion. 
In such a process of formation the opposite axes of curvi- 
linear motion must move reversely to each other, and there- 
fore repel. Thus the circles of motion would tend to 
expand, the centrifugal energy of rotation being aided by 
* Such curved lines of motion arising in one hemisphere of a globe are not 
produced by an attraction actually residing at the centre, but by the attractions 
of the opposite hemisphere. But these attractions are mutual, and their results 
must be equally balanced. The variation from a straight line of motion in any 
particle must be met by an equal opposite variation in some other particle or 
particles. No particle is fixed and incapable of variation in direction, and 
therefore the fixed balance in opposite directions of motion cannot be disturbed 
by any such mutual exercise of attraction.
