170 G. Jones an the Zodiacal Light. — 
These masses ought to take a spheroidal form, with a movement 
of rotation in the direction of the rotation, since the inferior 
molecules have a motion less than the superior ones; they have 
thus formed so many planets in a state of vapor. But, if one of 
them has been sufficiently powerful to unite, successively, by 18 . 
attraction, all the others around its centre, the ring of vapor 
will have thus become transformed into only one spheroidal mass 
of vapors, circulating around the sun with a rotation in the same 
direction as its revolution. Now, if we follow the changes which 
further pong ought to produce in the vapory planets, of whose 
ave just spoken, we shall see grow up in the cen 
condition, the planet resembles perfectly the sun in the nebulous 
State, in which we have just been considering it; the cooling 
f its atmosphere,
