See Connoisselr. COGNO'VIT (Lat., he has acknowledged). A written confession of liability by the defendant in an action authorizing the plaintiff to enter judgment for a specified sum, either absolutely or upon terms as to time of entry or payment. It is given only after the action is begun, and before the defendant has answered or otherwise pleaded, and in this respect ditTers from a con- fession of judgment, now used in England and in most of the States of the United States, which is given before the action is commenced, but is about the same in form. As originally used, the cognovit is superseded in almost every jurisdic- tion to-d.ay by an order of the court entered on consent. It is still in use in some of the States of the United States where common-law plead- ing is still retained. COGSTVELL, Joseph Green (1786-1871). An American librarian and bibliographer.

COG-WHEEL. See Gear-Wheel. COHABITATION (from Lat. cohaUtatio, from eoliitbitaie, to dwell together, from eo-, to- gether + habitare, to dwell. The act of a man and woman in living together as husband and wife. Cohaliitation does not necessarily in- volve tile notion of sexual intercourse, and, in a strict legal sense, as applied to hus- band and wife, may mean only consortium, and not concuhitus : but the term is com- monly held, even in law, to carry with it the latter implication, and this is always so where the parties are unmarried. It raises a legal pre- sumption of marriage between the parties co- habiting, which may, however, be rebutted by other evidence. .See Marriage, and the authori- ties there referred to.
