The determination of the refractive indices of liquids, utilizing a hollow prism mounted on a one-circle goniometer, is a well known procedure (Larsen and Berman, 1934). The purpose of this paper is to discuss the extension of the same method to two-circle goniometers of the Goldschmidt type. Such goniometers (Wolfe, 1948) are comprised of three structural units: the signal collimator which is fixed in position; the telescope which is movable parallel to the horizontal circle but is not attached to it; and the vertical circle unit, which is movable and which is attached to the horizontal circle. This paper stems from the lack of connection between the telescope and the horizontal circle.
