COMMIXTION, civil law. This term is used to signify the act by which goods 
are mixed together. 
     2. The matters which are mixed are dry or liquid. In the commixtion of 
the former, the matter retains its substance and individuality; in the 
latter, the substances no longer remain distinct. The commixtion of liquids 
is called confusion, (q.v.) and that of solids, a mixture. Lec. Elem. du
