ABSTRACT
There is-so to speak-in every child a painstaking teacher, so skillful that he obtains identical results in all children in all parts of the world. The only language men ever speak perfectly is the one they learn in babyhood, when no one can teach them anything! Not only this, but if at a later age the child has to learn another language, no expert help will enable him to speak it with the same perfection as he does his first.
