  An  instrument  for  measuring  angles,  especially  the  angles  of

  {Contact,  or  Hand},  {goniometer},  a  goniometer  having  two 
  movable  arms  (ab,  cd),  between  which  (at  ab)  the  faces  of 
  the  crystals  are  placed.  These  arms  turn  about  a  fixed 
  point,  which  is  the  center  of  the  graduated  circle  or 
  semicircle  upon  which  the  angle  is  read  off 
 
  {Reflecting  goniometer},  an  instrument  for  measuring  the 
  angles  of  crystals  by  determining  through  what  angular 
  space  the  crystal  must  be  turned  so  that  two  rays 
  reflected  from  two  surfaces  successively  shall  have  the 
  same  direction;  --  called  also  {Wollaston's  goniometer}, 
  from  the  inventor.
