obe as a cotton-wool holder, and a palate retractor should be in readiness. Good illumination is important, and may be obtained from an electric light, or from a Welsbach or Argand burner. The light should be placed close to, and on a level with, the patient's left ear. Both the anterior and posterior nares should be examined. _Anterior Rhinoscopy._--Before the introduction of the speculum the tip of the nose should be tilted up and the interior of the vestibule and the anterior part of the septum examined. In this way the existence of eczema or small furuncules, the presence of dilated or bleeding vessels upon, or a perforation of, the anterior part of the septum may be noted, and the general appearances observed. After inserting the speculum into the vestibule and dilating it, the following parts should be sought for and examined:--Close to the floor, and attached to the outer wall of the nasal cavity, is the anterior end of the inferior concha or turbinated body (Fig. 267), which overhangs the inferior meatus. It presents a pink appearance, and its size varies in different persons. At a higher level and on a posterior plane is the anterior end of the middle concha or turbinated body, which is of a paler colour than the inferior, and is only visible when the head is tilted backwards. Between it and the inferior turbinated body is the middle meatus, with which communicate the openings of the maxillary sinus, the frontal sinus, and the anterior ethmoidal cells. A considerable area of the anterior part of the nasal septum is also visible by anterior rhinoscopy, and between it and the middle turbinal is a narrow chink--the olfactory sulcus. [Illustration: FIG. 267.--The outer wall of Left Nasal Chamber, after removal of the middle turbinated body. (After Logan Turner.)] _Posterior Rhinoscopy._--Examination of the posterior nares and naso-pharynx is frequently attended with difficulty. The patient is directed to breathe through the nose, the tongue is depressed with a spatula, and a small-sized laryngeal mirror, comfortably warmed and with its reflecting surface turned upwards, is introduced behind the soft palate. When a good examination of the naso-pharynx is obtained, the following parts may be seen reflected in the mirror: the posterior surface of the uvula and soft palate, and above them, in the mesial plane, the posterior free edge of the septum nasi; on each side of the septum the apertures of the posterior na
