D'egras \D['e]`gras"\, Degras \Deg"ras\, n. [F.; cf. F. gras, a.
   & n., fat.]
   A semisolid emulsion produced by the treatment of certain
   skins with oxidized fish oil, which extracts their soluble
   albuminoids. It was formerly solely a by-product of chamois
   leather manufacture, but is now made for its own sake, being
   valuable as a dressing for hides.
