    actual improvement is perceptible. Disagreeable sen- sations in the ears generally attend deafness, which the use of the air-douche dispels for several days. I have often had to catheterise for months, at intervals of two or three days, persons whose deafness I had pronounced incurable, but who persevered in the operation from the comfort it afforded. ‘The use of the air-douche simply, is often of much service in promoting the return of the membranes of the middle ear to the natural condition, restoring the mucous secretion to the dry surface, and favouring the secretion of wax in the meatus externus. After a time the stream of com- pressed air does not produce so good an effect as at first, upon which I omit the air, and commence with medicated vapour, using a few drops of sulphuric ether, which, diluted with water, and having the air passed through it before entering the ear, impregnates the air sufficiently to render it inflammable. Much more may be effected by the alternate use of air and vapour than by the continuance of either; or this plan may be sus- pended altogether for a short time, and resumed with great effect. If it restores the secretion to the middle and external ear, the hearing is sure to be improved. The use of the air and vapour-douche may be accom- panied by other means to invigorate the constitution when this is required, and for the removal of any local disorder. I usually prescribe a course of sarsaparilla and the hydriodate of potash, in the doses adverted to when treating of another part of my subject. No me- dicine does so much good as this in the advanced stages of deafness. When the external passage is entirely dry it will often render the canal moist, and call forth the secretion of cerumen. This alone is a great service; =,
