   7. Relation of direction toward an object or end; as, look at
      it; to point at one; to aim at a mark; to throw, strike,
      shoot, wink, mock, laugh at any one.

          regarded as a mere point of locality. ``An English
          king was crowned at Paris.'' --Macaulay. ``Jean
          Jacques Rousseau was born at Geneva, June, 28, 1712.''
          --J. Morley. In regard to time, we say at the hour, on
          the day, in the year; as, at 9 o'clock, on the morning
