body, is directly as the amount of magnetic force in that body. 
Thus if two bodies be suspended near a revolving magnet, 
rotation will take place most rapidly in that which is the 
more magnetic. 
When, then, we find a vast planet like Jupiter rotating in 
about 10 hours, whilst one like Mars merely performs the 
same movement in 24 J hours, we may, upon the above 
hypothesis, explain the fact, by the higher magnetic condition 
upon the former sphere allowing the sun's rotation to produce 
the greater effect. 
It thus appears not only possible but highly probable, that 
the rotation of a world is a secondary effect, which depends 
upon the rotation of the guiding orb, and the conditions 
which exist in the world itself. It may be asked what causes 
the sun to rotate ? And this question will but serve to remind 
us that, however far we may advance in science, we shall 
still have a vast ocean of the unknown beyond us, for each 
step will but enable us to perceive that a greater distance 
separates us from the Creator than could ever be realised, or 
even dreamed of, by those whose minds are contracted, and 
who fear to investigate nature's laws, lest they might rival 
the wisdom of the Author of nature! At present it is merely 
intended to suggest that the rotation of a world may be con- 
nected with the rotation of the sun, and is probably produced 
by it. We may consider the various results which follow 
this probability, without rejecting it simply because we 
cannot explain the next step. We know that the earth's 
shadow causes a Lunar eclipse, and this we esteem a fact 
worth knowing, although we cannot explain how the sun 
gives its light to us, and hence produces a shadow by 
contrast. Thus we may, step by step, advance from the 
unknown to the obscure, from the obscure to the probable, 
from the probable to the certain. With this intention the, 
rotation of the planets has been thought upon. This rotation
