Rhombus
Definition:
(n.) Same as Rhomb, 1.
Example Sentences:
(1) The calculation has shown that the rounding of one of the angles of interference rhombus and its displacement towards the centre of the picture speak about either a functional deficiency of a muscle inserted into the eye ball in this place or about displacement of the point of its insertion from the limbus along the meridian of its action; displacement of one the angles of interference rhombus from the meridian speaks about displacement of the point of efforts exertion of the corresponding muscle into the same direction.
