The arm, n p, which carries the lenses, is attached to the triangular bar, rf, by a conical pin, on which it can turn hori- zontally, and the arm itself can be made longer or shorter by means of a rack and pinion, m o, attached to it, hence the lens, q, may be applied to all parts of an object without interfering in any way with the stage.
