Deaf Mutes Taught To Speak - New Treatment at London Clinic. Remarkable work is bring done to teach deaf-mute babies to hear and speak at the research clinic for deaf mutes, and the infants hospital, Vincent Square, London, and is really the first attempt to train deaf-mute babies to speak. The child who has no hearing, cannot perceive sound - therefore, cannot produce it, so, is dumb ***** the work in the clinic aims at the earliest possible co-operation between, and co-ordination of, touch and sight as a substitute for the absent hearing sense.
