For Example, There Are Numbers Of Chemists Who Occupy Themselves Exclusively With The Study Of Dyestuffs. They Discover Facts That Are Useful To Scientific Chemistry; But They Do Not Rank As Genuine Scientific Men. The Genuine Scientific Chemist Cares Just As Much To Learn About Erbium-the Extreme Rarity Of Which Renders It Commercially Unimportant-as He Does About Iron. He Is More Eager To Learn About Erbium If The Knowledge Of It Would Do More To Complete His Conception Of The Periodic Law, Which Expresses The Mutual Relations Of The Elements.
