THOUGHTS ON NATURAL PHILOSOPHY. 15 
The granules, corpuscles, atoms, and molecules are con- 
tinually moving, and at different speeds, through space, and 
as a result of contact and the exercise of force, are grouping, 
breaking up, and grouping again according to their speed, 
weight, and movement; and this speed, weight, movement 
and arrangement gives to substances their distinguishing 
characteristics. The names we give to the temporary 
arrangements of matter are merely words. 
The granules of matter, and their necessary accompani- 
ment of speed, weight, movement and arrangement are 
sufficient to account for the universe, and all natural 
phenomena, which follow as a natural consequence of the 
existence of those granules and their accompaniment of 
speed, weight, movement, and arrangement. 
The strong support given to the theory by the works of 
Sir Norman Lockyer and others on the stars may be here 
alluded to. In the hottest stars hydrogen and proto-hydrogen 
are the only predominant elements. The energy is so great 
that the granules, atoms, etc., are kept at such a high rate 
of speed that it is impossible for them by degrees of cooling 
to attain such variety of speeds as to produce a great variety 
of combinations of substance. When all are driven at such 
high speed differences are eliminated, and matter appears 
near to its simplicity. It is the difference in the rates of 
speed between the very highest and the lowest, combined 
with the varieties of movement and arrangement and the 
question of weight, which has an important bearing when 
the groups clash, that accounts for the many differences of 
materia! combinations of substance. 
The truth of the theory is also demonstrated daily the 
world over by electrical accumulators. Energy, in the form 
of material motion, is being forced into accumulators and 
stored there for future use. The only way in which it is
