son Dumb and Deaf, to Speak and to Understand a Language. Of which if he could do either, the other would be more easy: But his knowing neither, makes both harder. And though the Former may be thought the more difficult; the Latter. may. perhaps require, as much of Time. For if a considerable Time be requisite, for him that can speak One, to learn a Second Language; much more for him that knows None, to learn the First.
