*Figure I, C*, is a brass circle, about two feet in diameter, moving vertically upon two pivots between two stone pillars, having an index or hand turning round horizontally on the center of this circle, which is divided into 360 parts; but there are no counter-divisions on the index to sub-divide those on the circle. This instrument appears to be made for taking the angle of a star at setting or rising, or for taking the azimuth or amplitude of the Sun at rising or setting.
