Microcrith
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 This unit is no longer used, and has been replaced by the {Dalton}, which is of approximately the same value.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. [1913 Webster +PJC]
