32 Matter and Motion. 



we can form no idea of them, for whether 

 we view animate or inanimate matter, 

 the corpuscles of which it is formed ^re 

 so infinitely small, as not only to escape 

 the scrutiny of the highest magnifying 

 powers in glasses, but even imagination 

 itself is incapable of forming an idea of 

 an original particle of matter : One pound 

 of gold is capable of covering a wire that 

 will circumscribe the globe, nay, so infi- 

 nite is this divisibility that Lewenhoeck 

 discovered more living animalcules in the 

 milt of on^ single cod-fish than there are 

 jnen, women, and children on the face of 

 the earth ! and those so small that many 

 thousands may stand upon the point of a 

 needle. And if we suppose that these 

 animalculae are furnished with blood, like 

 other animals, and if the globules of their 

 blood bear the same proportion to their 

 bulk as those of a man bear to his body, it 

 may be proved, that the smallest visible 

 grain of sand would contain more of these 

 globules than 10,256 of the largest moun- 

 tains in the world would contain grains 

 of sand. 



When we consider these tilings we 

 seem to look down into infinity j and as.
