(brunt’ ∂n) A small pocket compass with levels, sights, and a mirror reflector, used for measuring angles as well as for determining directions. See Figure B-9. Various arrangements of the sights and mirror permit one to sight on objects and simultaneously read the scale. The Brunton is often used as a protractor. Named for David W. Brunton (1849–1927), American engineer.
