Morrison Waite,
Arthur v. Dodge — Opinion of the Court
“ They are classified in the schedules as metals. All the elements of which they are composed are metals. Their manufacture consists in the combination of the several component parts. The tin is still tin, and the iron still iron. There has been no substantial chemical change. All their metallic qualities still remain. They are what they purport to be, manufactures of iron, tin, and sometimes lead, and the result is a new article of commerce, of which metals, as metals, form the component parts. ”
