     fr. Gr. kry`os icy cold, frost + fe`rein to bear.] (Chem.)
     An instrument used to illustrate the freezing of water by its
     own evaporation. The ordinary form consists of two glass
     bulbs, connected by a tube of the same material, and
     containing only a quantity of water and its vapor, devoid of


     air. The water is in one of the bulbs, and freezes when the
     other is cooled below 32[deg] Fahr.
