DUE PKOCESS OF LAW. 502 DtrFAURE. But for tlio flicck of this piiiui|>lo upon the legis- lature iinil the executive, hills of iittainiler. acts of confiscation, acts reversing juiljnnents, ami acts directly transferring one man's |iro|KTty to an- other might be resorted to. and the time-honored safeguards of constitutional liberty be swept away. It is not to lie understood, however, that the "law of the land' and 'due process of law' mean the body of legal rules or the system of judicial procedure which existed at the adoption of the Federal or of a particular State Constitution. These may be changed from time to time with- out violating the Constitution, provided the new l>rocedure or the new rules are in accmdancc with the fundamental principles and maxims of our jurisprudence. Moreover, a State may do many things in the exercise of its police power which ojierate to deprive |>ersons of liberty or iirojH-rty in a very siuumary way, without violating the constitutional provisions under consideration. It may also authorize the sale of property for non- payment of taxes, without any judicial proceed- ing. But these acts arc not ]>erfornied without due process of law, since the Slate is acting in accordance with those principles governing and limiting the rights of the State and its sil)jects, not at x-ariance with them. "In short, "due pro- cess of law' in each particular case means such an exercise of the powers of government as the settled maxims of law permit and sanction, and under such safeguards for the protection of indi- vidual rights as those maxims prescribe for the class of cases to which the one in question be- longs."

A coiii|Hisition for (wo voices or instruments, with or without an neeompaniment of one or more instruments. In technical language. (/i/(7 is applied to a composition for two voices or in- struments of the same kind, while duo refers to one for two voices or instrumeiits of diderent kinds. Due(s are divided into three classes, in all of which, however, the form is much the same. The dramatic duct can of necessity have no fixed form, as it must vary according to the dramatic situation. The f^tahat Mater of Pergo- lesi is a splendid example of the church duet, while the soui) ducts of Meiidels-iohn follow the general idea of duets as ori'_-iiiatcil in the seven- teenth century and developed in the eighteenth by Sted'ani and.
