Lucius Quintus Cincinnatus Lamar, Pacific Exp. Company v. Seibert…
“ This court has repeatedly laid down the doctrine that diversity of taxation, both with respect to the amount imposed, and the various species of property selected either for bearing its burdens or for being exempt from them, is not inconsistent with a perfect uniformity and equality of taxation in the proper sense of those terms; and that a system which imposes the same tax upon every species of property, irrespective of its nature or condition or class, will be destructive of the principle of uniformity and equality in taxation, and of a just adaptation of property to its burdens. ”
