He condemned the common phrases "deaf and dumb" and "deaf-mutes," as expressing what is not true; showing that those whom we term "deaf-mutes" have no other natural defect than that of hearing, and that they are dumb not on account of lack of hearing, but of lack of instruction. No one teaches them to speak. The gesture-language which such a child may use is developed by him at home, not because it is the only form of language natural to one in his condition, but because his parents and friends neglect to use the English language in his presence in a clearly visible form. The sign-language of our institutions is objected to as an artificial and conventional language, so far from being natural that it is not understood by deaf children on their entrance to an institution, and hearing persons can not be qualified to teach it till after many years. Practice in it hinders the acquisition of the English language; makes the deaf associate together in adult life, and avoid the society of hearing people; and thus causes the intermarriage of the deaf and the propagation of their physical defect. Dr. Bell holds that written English can be taught to deaf children so as to become their vernacular, and that, when they have been made familiar with it in either its written or spoken form, they can be taught to understand the
