    head mirror for reflecting the light on the patient; it may be worn in the same manner as in examining- the larynx, i.e., either attached to a spectacle frame, or a forehead band. 3rd, a rhitioscopic mirror; this may be either the smallest size laryngeal mirror, or the infinitely more convenient form of this specially arranged for rhinos- copy. The mirror in this instrument can be moved by a trigger attached to the handle, from the horizontal plane to a right angle, which greatly facilitates its use. It is repre- sented half size in the adjoining cut, 4th, a tongue depressor. This is usually made too large in the blade; several sizes should be at hand, and each should be fitted at right an- gles to a handle. Various patterns are in use, but the observer will adopt that form which in practice he finds most convenient to himself. 5th, Anterior nasal specula. These are very numerous and vary much in utility. The choice will depend upon whether the object is diagnostic only, or whether it is to assist operative procedures. In the former case, i.e., for observing the anterior nares, I generally prefer Kramer's ear speculum, because of the facility of introducing it, and because the distension of the blades being independent of a spring can be controlled by the observer, so as to avoid giving pain. In proceeding with any instrument to expand the anterior nares, the ex- treme sensitiveness of these orifices should be borne in mind, and, also, that the dilatable portion is limited to the region from which true cartilage is absent. It is neces- sary therefore to avoid any approach to roughness in this manipulation, as otherwise the natural objection which patients manifest at any interference with the nose, will be
