		This had already been done by O. Romer about 1704, but the idea had not been adopted by any one else, except in the transit circle constructed by Edward Troughton for Stephen Gropmbridge in 1806.
		The transit circle in the form given it by Reichenbach had one finely divided circle attached to one end of the horizontal axis and read by four verniers on an " alidade circle," the unaltered position of which was tested by a spirit level.
