Hardness of hearing may be produced by cold, mechanical injury, various diseases, and in many cases, as where it occurs in the aged, be developed without pain, and give to the patient no clue to its cause.
Sometimes from birth, the ears are impervious to all sound, and consequently the child, having no guide in the sound of others' voices for the modulation of his own, is not only deaf but dumb. This condition at first thought so dreadful, is now through the interposition of science and our various excellent asylums, deprived of half its terrors.
We shall only have space to give some of the leading indications for the treatment of the various forms of deafness, yet sufficiently full however for domestic practice, as it is often complicated with other difficulties rendering the skill of the physician essential.
