    Gentlemen of more than ordinary dimensions.

  3. The degree of manifoldness of a quantity; as, time is quantity having one dimension; volume has three dimensions, relative to extension. (Math.)
  4. A literal factor, as numbered in characterizing a term. The term dimensions forms with the cardinal numbers a phrase equivalent to degree with the ordinal; thus, a2b2c is a term of five dimensions, or of the fifth degree. (Alg.)
