An international system of electro-therapeutics : for students, general practitioners, and specialists . Fig. 4.—Gaertners ElectricLamp. NOSE, NASO-PHARYNX, PHARYNX, AND LARYNX. 1-7 small electric lamp mounted at the end of an ordinary galvano-canteryknife-shaft, behind and above the soft palate. This enables the operator,by looking into the nostrils, using a Duplay speculum with elongatedand fenestrated branches, to examine all the parts usually seen with diffi-culty by means of anterior rhinoscopy. When septal deviation or othermalformation or neoplasms do not interfere, the naso-pharynx and theposterior two-thirds of the anterior cavities can be examined directly ;while transparent media may also be brought under scrutiny, if theyproject beyond the line of normal parts. The degree of light requiredneed not be that necessitated for reflected light, as in instrumentsin which lamp and mirror are mounted together at tlie extremity ofthe handle ; a much smaller lamp can therefore be employed and undueheat avoided. The parts to be examined should first be freely Fig. 5.—Jacksons Apparatus.* Yoltolini, of Breslau,^ also introduced a method based upon the sameprinciples, but including the nasal walls, the accessory cavities, and thelarynx in the sphere of visual inquir}^ For the examination of thelarynx the lamp is applied to the external surface of the neck, at thepomum Adami or near the cricoid cartilage, and the heated lar3ngo-scopic mirror is introduced into the dark pharjux. Freudenthal, of NewYork,2 at a meeting of the Laryngological Section of the New YorkAcademy of Medicine, thus described the results observed : The lightis quite different from that ordinarily obtained. The first thing thatstrikes the observer is the absence of different colors. The whole larjmxshows a reddish tint of varying intensity.
