STATEMENT No. 5. 



All matter consists of finite but very minute objects, 

 called "atoms" (discrete units), which combine to 

 form objects called "molecules" (complex units). 

 Molecules attract molecules, and cohere to form 

 " cells." The grouping of atoms and molecules 

 makes " mass. 9 ' 



IT is absolute] y impossible to get away from the above 

 grand fundamental truths. The science of chemistry 

 rests upon it, and would cease to exist as a science if this 

 fundamental statement were questioned. Sir Robert 

 Ball, in a forcible way, develops the conception thus : 

 " Take a lump of loaf sugar and crush it in a mortar, 

 ach of the fragments is, of course, a particle of sugar 

 still. Let the operation of grinding be carried on until 

 the entire lump has been reduced to powder of the 

 utmost fineness, which any grinding apparatus is 

 capable of effecting. Each of the minute particles is 

 still, nevertheless, a fragment possessing the attributes 

 and properties of sugar. It has the sweetness and the 

 hardness, the solubility and the chemical composition 

 of the original lump. There is a difference in dimen- 

 sions, but no difference of any other kind. But now 

 let us suppose that we were in possession of some 

 pulverizing apparatus which would permit the reduction 

 of the sugar to be carried on to an extent far greater
