More than 110 years ago

Here is a bit of history. The paragraph below as published in the June 1907 issue of Scientific American magazine—more than 110 years ago:

The loss of the sense of hearing should not necessarily mean deprivation of the power of speech. Is it only within recent years that we have come to realize this fact, and in up-to-date institutions the old –fashioned finger alphabet is now unknown. Every child is taught to speak in the natural way by means of the vocal organs. The four or five years of the primary course are devoted almost exclusively to the acquirement of language and numbers.
