The greater our horizon, the more we can take in, the more we can give out. Our soul is scarcely ours when enchained; the greater its liberty, the more it belongs to us. Hence our just pity for the congenital deaf, and our desire to assist them in their efforts at expression. Those among them who are being, or have been, tutored, receive their impressions through their eyes in the form assumed by the speaker's mouth; the eye assuming the function of the ear. The form assumed by their teacher's mouth, however, not being perfect, a perfect impression cannot be made. Hence the expression of the deaf is in conformity with the impression they have obtained: mechanical, material, soulless. The exterior lines of the mouth of the teacher, or any other speaker's from which the deaf draw their inspiration, are those of the material side of the medal. Failing to see the reverse side thereof, namely, the interior of the mouth, which is its spiritual side, the lines of the latter make no impression upon them. These fine lines on the interior side of the speaker's mouth, representing the rhythm, the soul of the voice, not being seen, fail to make that impression from which alone a soulful expression could arise. That an _impression_ may be made through the eye will scarcely require a defense, in view of the fact that in reading aloud or in singing from notes the _entire_ impression is made through the eye. The reader or singer, knowing the _value_ of every sound, is impressed by the sight of a letter or a note as he would be by the sound itself. Not so with the congenital deaf, who, being ignorant of such value, cannot reproduce it. Nor will it be contended, I suppose, that the deaf knowingly, designedly, or volitionally attempt to imitate the forms assumed by the teacher's mouth, but it will be admitted that this is done spontaneously, and that vocal sounds with them arise from this imperfect mechanism, thus involuntarily reproduced. With the congenital deaf, with persons attempting to speak a foreign language, etc., the material form, as well as the spiritual impetus, being imperfect, the expression will be in conformity therewith. In how far and in what manner these investigations may become helpful to the deaf will be a matter for the not distant future to develop. That they will eventually become of the greatest aid to them I have every reason to believe. Those who have made a study of matters of this kind understand the difficulties surrounding the same. These difficulties are increased manifold where the ear of the scholar absolutely refuses to come to his own and his teacher's aid.
