Miss Sullivan brought her to Miss Fuller's school one day and she received her first lesson, of about two hours' length.
"The child's hand was first passed over Miss Fuller's face, mouth, and neck, then into her mouth, touching the tongue, teeth, lips, and hard palate, to give her an idea of the organs of speech.

Miss Fuller then arranged her mouth, tongue, and teeth for the sound of i as in it.

She took the child's finger and placed it upon the windpipe so that she might feel the vibration there, put her finger between her teeth to show her how wide apart they were, and one finger in the mouth to feel the tongue, and then sounded the vowel.

The child grasped the idea at once.

Her fingers flew to her own mouth and throat, and she produced the sound so nearly accurate that it sounded like an echo.
