Vigilance \Vig"i*lance\, n. [L. vigilantia: cf. F. vigilance.]

      sleep; wakefulness.
      [1913 Webster]

   2. Watchfulness in respect of danger; care; caution;
      circumspection. --Cowper.

            And flaming ministers to watch and tend
            Their earthly charge; of these the vigilance
            I dread.                              --Milton.

VIGILANCE. Proper attention in proper time. 
     2. The law requires a man who has a claim to enforce it in proper time, 
while the adverse party has it in his power to defend himself; and if by his 
neglect to do so, he cannot afterwards establish such claim, the maxim 
vigilantibus non dormientibus leges subserviunt, acquires full force in such 
case. For example, a claim not sued for within the time required by the acts 
of limitation, will be presumed to be paid; and the mere possession of 
corporeal real property, as if in fee simple, and without admitting any 
other ownership for sixty years, is a sufficient title against all the 
world, and cannot be impeached by any dormant claim. See 3 Bl. Com. 196, n; 
4 Co. 11 b. Vide Twenty years.
