   a.]
   The eighth month of the year, containing thirty-one days.

   Note: The old Roman name was Sextilis, the sixth month from
         March, the month in which the primitive Romans, as well
         as Jews, began the year. The name was changed to August

         Rome, on account of his victories, and his entering on
         his first consulate in that month.
