Note 8 — Chapter I

A somewhat frequent classification of the deaf in respect to their power to speak is to regard them roughly as falling into three great divisions: 1. "Deaf-mutes," who come nearest to being deaf and dumb. They have always been deaf, and have never had natural speech. What speech they may possess has come from special instruction, with the result that it is more or less artificial. 2. "Semi-mutes," who are deaf, but who have once had hearing as well as speech; and this speech they are able to use to a greater or less degree, though in time it is likely to become more and more astray. 3. "Semi-deaf" persons, who are only partly deaf, and possess a little hearing, though it is too slight to be of real practical use; and who have voices most nearly approaching the normal. They belong somewhere between the really deaf and the hard of hearing.
