    all events, every effort may be made to stay the natural tendency of the decaying sense to arrive at complete extinction. Stricture of the Eustachian Tube.—W here this exists (and it does exist much more frequently than is gene- rally admitted), it does not follow that the recovery of the hearing is impossible. I believe the removal of the stricture ought to be attempted, on the same principles as when present in the urethra. Dilatation, with a bougie, has not only been said to be a hopeless under- taking, but the possibility of passing such an instrument into the tympanum has been denied. I admit the great difficulty of the manipulation; but still I have often succeeded in passing a fine whale-bone bougie, as pro- posed by Gairal, into the tympanum. When it has been accomplished, the patient has felt asif the point of the instrument actually presented at the external mea- tus, and the sensation is so deceptive that it is usual to see him put up his finger, thinking to touch it. But to place the matter beyond all doubt, I have, in more than one instance, seen the bougie by means of a speculum and lamp, its black colour showing plainly through the semi-transparent membrane of the drum. When, there- fore, from the inability of injecting air, the absence of mucous gurgling, and the deafness supervening on sore- throat, there is reason to believe that stricture of the tube exists, the use of the bougie should certainly be had recourse to, and will, unquestionably, sometimes be of service. Iodine ought also to be administered in the manner, and with the intention proposed by Dr. Manson, of Nottingham.
