Diseases of the nose and throat . Fig. 8. Jarvis Nasal dilatable, hence the importance of using a speculum theseparation of whose blades may be regulated at will. All fenestratedinstruments, with uncontrolled springs, are to be condemned. In 32 DISEASES OF THE NCSE AND THROAT. operating far back in the nasal cavity the Jarvis speculum (Fig. 8).is found to be more convenient, since it is lighter and more properlyself-retaining, and is less apt to get in the way of the operator. No rhinoscopic examination should be considered complete untilinspection of the mucous membrane has been supplemented by pal-pation with the probe. We thus gain information as to thevascularitv, the density and the mobility of the structures normal or. Fig. 9. Jarvis Rhinometer. morbid. It is also frequently important to determine the sensitive-ness of the pituitary membrane, or to define areas of suspected hyper-esthesia. If still more exactness is desired we may measure the widthof the nasal passages at various points by means of Jarvis rhinom-eter. or the thickness of the septum with Seders septometer ( and 10). In posterior rhinoscopy we frequently have to contend with variousobstacles, such as a rebellious tongue which resents the pressure of
