A treatise on the diseases of the ear including the anatomy and physiology of the organ together with the treatment of the affections of the nose and pharynx which conduce to aural disease . ^ into the naso-pharynx, the soft palate should be previously painted ^ith asolution of cocaine, and, when anaesthetised, held forward bymeans of a soft palate tractor. The danger of inflammationextending along the Eustachian tube and producing suppurationin the middle ear must not be forgotten. When cauterising a. Fig. 81. Thl, Althors Electk()1>Ii, Handlk. nostril, care is necessary to prevent two opposite parts of thecavity beins- touched with the electrode, because if both surfaceshave been burned, the}- are liable to unite when they come inapposition, as a result of the swelling of the tissues which alwaysfollows the operation. It is usually advisable to wait about afortnight before again applying the cautery, so as to allo^^ allinflammatory swelling to subside and healing to be thoroughlycompleted. As substitutes for the galvano-cautery, various chemicalagents are a^ailable for the destruction of hypertrophied por-tions of the mucous membrane, but the objection to their useis that their action cannot be precisely limited. The mostefficacious of these are: chromic acid, glacial acetic acid, nitrate CHRONIC CATARRH OF THE XASO-PHARYNX. 257 of silver, chloride of zinc (a concentrated solution), and nitrateof mercury. If a proper chromic acid carrier (Fig. 82), is notat hand, a silver probe
