  Gelatin  \Gel"a*tin\,  Gelatine  \Gel"a*tine\,  n.  [F.  g['e]latine, 
  fr  L.  gelare  to  congeal.  See  {Geal}.]  (Chem.) 
  Animal  jelly;  glutinous  material  obtained  from  animal  tissues 
  by  prolonged  boiling.  Specifically  (Physiol.  Chem.),  a 
  nitrogeneous  colloid,  not  existing  as  such  in  the  animal 
  body,  but  formed  by  the  hydrating  action  of  boiling  water  on 
  the  collagen  of  various  kinds  of  connective  tissue  (as 
  tendons,  bones,  ligaments,  etc.).  Its  distinguishing 
  character  is  that  of  dissolving  in  hot  water,  and  forming  a 
  jelly  on  cooling.  It  is  an  important  ingredient  of 
  calf's-foot  jelly,  isinglass,  glue,  etc  It  is  used  as  food, 
  but  its  nutritious  qualities  are  of  a  low  order
