the faces of the crystals are placed. These arms turn

Reflecting goniometer, an instrument for measuring the

space the crystal must be turned so that two rays
reflected from two surfaces successively shall have the

attached to it, which reflects a ray of light or the image
of a scale; -- called also mirror galvanometer.
