  Deuto- \Deu"to-\or Deut- \Deut-\ (d[=u]t-)[Contr. from Gr.
     dey`teros second.] (Chem.)
     A prefix which formerly properly indicated the second in a
     regular series of compound in the series, and not to its
     composition, but which is now generally employed in the same
     sense as bi- or di-, although little used.
     [1913 Webster]

     to E. two. See Bis-, Two, and cf. Di-, Dis-.]
     [1913 Webster]
     1. In most branches of science bi- in composition denotes
        two, twice, or doubly; as, bidentate, two-toothed;
        biternate, doubly ternate, etc.
        [1913 Webster]
  
     2. (Chem.) In the composition of chemical names bi- denotes
        two atoms, parts, or equivalents of that constituent to
        the name of which it is prefixed, to one of the other
        component, or that such constituent is present in double
        the ordinary proportion; as, bichromate, bisulphide. Be-
        and di- are often used interchangeably.
        [1913 Webster]
