A rectal speculum combining both a direct and a lateral view without removal and reinsertion of the speculum is of advantage both in examining the rectum and in operative work. The instrument I use is essentially a short, split, circular tube provided with an obturator and also with a hinge joint on its inferior surface; the handles controlling the sides are kept apart by a spring between them or in any intermediate position between "open" and "closed" by means of the automatic rachet-way between the handles. A long lip on the edge of the rachet-bar effectually prevents pinching of the mucosa on withdrawing the instrument, as complete closure cannot be made except by deliberate attempt. To use this instrument as an ordinary proctoscope or anoscope, it is merely inserted and the obturator removed.
