Man, born deaf,: and; confequently dumb, may come' to underhand both 
them, and by them the Mind of him that forms them 5 Whcrekis obferved, 
that a Man born deaf is not altogether deftitute, of all Motion of- his Tongue, 
and that he may be taught to underhand: others by the Motions, of their 
Motit|i apd; Tongue, muth after the manner as : others are taught to read \
