Calamine \Cal"a*mine\ (k[a^]l"[.a]*m[imac]n or -m[i^]n), n. [F.
   calamine, LL. calamina, fr. L. Cadmia. See {Cadmia}.] (min.)
   A mineral, the hydrous silicate of zinc.
   [1913 Webster]

   Note: The name was formerly applied to both the carbonate and
         silicate of zinc each of which is valuabic as an ore;
         but it is now usually restricted to the latter, the
         former being called smithsonite.
