  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
  Buoyancy  \Buoy"an*cy\,  n.;  pl  {Buoyancies}. 
  1.  The  property  of  floating  on  the  surface  of  a  liquid,  or  in 
  a  fluid,  as  in  the  atmosphere;  specific  lightness,  which 
  is  inversely  as  the  weight  compared  with  that  of  an  equal 
  volume  of  water. 
  2.  (Physics)  The  upward  pressure  exerted  upon  a  floating  body 
  by  a  fluid,  which  is  equal  to  the  weight  of  the  body; 
  hence  also  the  weight  of  a  floating  body,  as  measured  by 
  the  volume  of  fluid  displaced. 
  Such  are  buoyancies  or  displacements  of  the 
  different  classes  of  her  majesty's  ships.  --Eng. 
  3.  Cheerfulness;  vivacity;  liveliness;  sprightliness;  --  the 
  opposite  of  {heaviness};  as  buoyancy  of  spirits.
