Perjury
the taking of a wilful false oath or affirmation, by a witness lawfully required to depose the truth in a matter of some consequence to the point in question. A false oath, there fore, taken before no court, or before a court incompetent to try the issue in question, does not constitute the offense of perjury at common law. But many statutes in the United States, passed by the general government or the several States on the matter, provide that a false oath or declaration made on some specified occasions, or for some particular purposes, shall be considered to be perjury, and punishable accordingly. Perjury is a misdemeanor at common law, and by several statutes punishable by fine and imprisonment, and by penal servitude for a term not exceeding seven years.

Permian Period
the name given to the closing era of the Carboniferous age, which was a time of decline for Palæozoic life, and of transition toward a new phase of geological history. In the United States the Permian rocks are confined to the interior continental basin, and occur in the portion of it W. of the Mississippi, especially in Kansas. The rocks are limestones, sandstones, red, greenish, and gray marls or shales, gypsum beds and conglomerates, among which the limestones in some regions predominate. The Permian period was so called by Murchison, because he found them largely developed in that portion of Russia which composed the ancient kingdom of Permia, of which the actual government of Perm forms a part.

Permutation
the act of exchanging one thing for another; mutual intermutation. change; interchange; inte Also in mathematics, change or combination of any number of quantities. The different arrangements which made of any number of given quantities, when a certain number, or the whole of them, are taken together; thus the permutations of a, b, and c, taken two together, are ab, ac, ba, bc, ca, and cb. The number of permutations of n things taken two together is n (n-1); of n things taken three together, n(n-1) (n-2), and so on.

Permutations
in mathematics, the number of groups that can be formed with a given number of units, taking order into consideration. With a and b but one combination, ab; can be formed, but two permutations, ab and ba, are possible. Both of these permutations are the same combination. If three elements, a, b, and c, be taken we may have four combinations, ab, ac, bc, and abc; but each of the first three combinations is capable of two permutations, and the last combination is capable of six permutations, namely, abc, acb, bac, bca, cab, cba. The number of possible permutations with a given number of units forms a chapter in higher algebra.

By the action of strong sulphuric acid, barium sulphate is formed and oxygen set free. In ong su organic chemistry it applies to certain peroxides or organic radicals, produced by the action of barium peroxide on the anhydride of the radical.
