  Microcrith \Mi`cro*crith"\, n. [Micro- + crith.] (Chem.)
     The weight of the half hydrogen molecule, or of the hydrogen
     atom, at one time taken as the standard in comparing the
     atomic weights of the elements; thus, an atom of oxygen
     weighs sixteen microcriths. This unit is no longer used, and
     has been replaced by the {Dalton}, which is of approximately


     the same value. See {molecular weight} and {Crith}. --J. P.
     Cooke.
