» The castrated male is called a steer until it attains its full growth, and then, an ox ; but if castrated somewhat late in life, it is called a stag . The male, not castrated, is called a bull . These distinctions are well established in regard to domestic animals of this genus. When wild animals of this kind are spoken of, ox is often applied both to the male and the female. The name ox is never applied to the individual cow , or female, of the domestic kind. Oxen may comprehend both the male and the female.

Oxide noun [ French ox ygène oxygen + ac ide acid: confer French oxyde . The French word was correctly spelt oxide , till about the year 1840, when, in ignorance or forgetfulness of the true history and composition of the word, the orthography was change to make it represent the υ of Greek 'oxy`s , from which it was supposed to be directly derived.] (Chemistry) A binary compound of oxygen with an atom or radical, or a compound which is regarded as binary; as, iron oxide , ethyl oxide , nitrogen oxide , etc.

» In the chemical nomenclature adopted by Guyton de Morveau, Lavoisier,and their associates, the term oxides was made to include all compounds of oxygen which had no acid (F. acide ) properties, as contrasted with the acids, all of which were at that time supposed to contain oxygen. The orthography oxyde , oxyd , etc., was afterwards introduced in ignorance or disregard of the true etymology, but these forms are now obsolete in English. The spelling oxid is not common.

Oxidize transitive verb [ imperfect & past participle Oxidized ; present participle & verbal noun Oxidizing .] (Chemistry) To combine with oxygen, or subject to the action of oxygen, or of an oxidizing agent. Specifically: (a) To combine with oxygen or with more oxygen; to add oxygen to; as, to oxidize nitrous acid so as to form nitric acid. (b) To remove hydrogen from (anything), as by the action of oxygen; as, to oxidize alcohol so as to form aldehyde. (c) To subject to the action of oxygen or of an oxidizing agent, so as to bring to a higher grade, as an -ous compound to an -ic compound; as, to oxidize mercurous chloride to mercuric chloride.

» In certain cases to oxidize is identical with to acidify ; for, in nearly all cases, the more oxygen a substance contains the more nearly does it approximate to acid qualities; thus, by oxidation many elements, as sulphur, nitrogen, carbon, chromium, manganese, etc., pass into compounds which are acid anhydrides, and thus practically in the acid state.
