![conception of the immensity of the distance may be formed, when we reflect that light passes over 191,515 English miles in one second. The grand march of our sun, with his attendant planets, through the great ocean of space, at the annual rate of 154,185,000 miles,1 around a distant unknown centre, supports still more strongly the conclusion, that all the particles of matter in the universe are mu- tually related. Without this fixed relation of all the individual and component molecules of the universe, matter could not exist in its present condition. Destroy the mutual attraction of bodies, and the essential conditions for the existence of the universe will be destroyed. The existence of this law is independent of all others, and of every form, property, and affection of matter; whilst all the properties and affections of the various forms of matter, inorganic or organic, depend ultimately upon the existence of this fixed rela- tion of the molecules of matter. If our sun with his planets were blotted out of existence, this fixed relation of the remaining mole- cules of matter would not be destroyed. If sun after sun, and system after system, were blotted out of existence, it is reasonable to believe that this law would not be destroyed as long as two atoms of matter remained. The atoms of matter are bound together by a force which acts only at insensible distances, called the force of cohesion. It has been announced by some philosophers that the force of cohesion is nothing more than the force of gravity, acting between the indivi- dual atoms of bodies, at exceedingly small distances.
