Speciality \Spe`ci*al"i*ty\, n.; pl. {Specialities}. [See
   {Special}, and {Specialty}.]
   1. A particular or peculiar case; a particularity. --Sir M.
      Hale.

   2. (Law) See {Specialty}, 3.

   3. The special or peculiar mark or characteristic of a person
      or thing; that for which a person is specially
      distinguished; an object of special attention; a special
      occupation or object of attention; a specialty.

            On these two general heads all other specialities
            are depedent.                         --Hooker.

            Strive, while improving your one talent, to enrich
            your whole capital as a man. It is in this way that
            you escape from the wretched narrow-mindedness which
            is the characteristic of every one who cultivates
            his speciality.                       --Ld. Lytton.

            We 'll say, instead, the inconsequent creature man,
            - For that'a his speciality.          --Mrs.
                                                  Browning.

            Think of this, sir, . . . remote from the impulses
            of passion, and apart from the specialities -- if I
            may use that strong remark -- of prejudice.
                                                  --Dickens.

   4. An attribute or quality peculiar to a species.
