A text-book on diseases of the ear, nose and throat . e of them,as by the usual mirror method. The Kir-stein method has not come into generaluse, as the apparatus is somewhat ex-pensive and instruments for operativework with it must all have a special shape. The X-ray has also been used for examination of the larynx. It isuseful to detect tumors and foreign bodies, but, as a rule, whatever infor-mation it gives can be obtained by less cumbersome methods. Freuden-thal has applied the principle of translumination in examining thelarynx by means of adevice here yellowish-red lightis thrown throughthe laryngeal tissues,making their appear-ance quite differentfrom the ordinary. Finally, mentionmay be made of themethod of Killian forgetting a view of the posterior wall of the larynx. The patient standswith head well bent forward, while the examiner kneels in front of him,holding the mirror up against the uvula. It must be borne in mind, Position of neck and head duringexamination with the electric ortho-scope or autoscope. (Thorner.). Freudenthals electric lantern for translumination of the larynx.

In the Killian method the epiglottis appears in frontand the i)osterior laryngeal wall behind. The Laryngeal I:\rAGE.—Eeference to previous figures will showthat the laryngeal image is reversed in an antero-posterior direction, andthat portion of the larynx which is really farthest from the examinerseems nearest to him in the picture. There is no reversal of lateral posi-tion. Wliat is right or left in the mirror is right or left in the addition, the examiner must remember that he is sitting opx^osite tothe patient, so that his own right is the latter* s left.
