avoid memorizing. To prevent reading from memory, a hole 1/2 inch square may be
cut in a
only one letter at a time, and may be moved about so as to show the letters in irregular
order. A mistake of two letters on the 20 or the 30-foot lines, and of one letter on
piece of cardboard, which may be held against the test letters, so as to show
the 40 or 50-foot lines, may be allowed.
Whenever it is found that the child has less than normal sight, 20/20, in either
eye, that the eyes or eyelids are habitually red and inflamed, or that there is a com-
plaint of pain in the eyes or head after reading, the teacher will send a notice to the
parent or guardian of the child, as required by law, that the child's eyes need medical
attention
METHOD OF TESTING HEARING
If it is possible, one person should make the examinations for an entire school
in order to insure an even method. The person selected should be one possessed of
normal hearing, and preferably

The examination should be made with the whispered or spoken voice; the child
should repeat what he hears, and the distances at which words can be heard distinctly
should be noted.
The examiner should attempt to form standards by testing persons of normal
hearing at normal distances. In a still room the standard whisper can be heard easily
at 25 feet; the whisper of a low voice can be heard from 35 to 45 feet and of a loud
voice from 45 to 60 feet.

For the purpose of acquiring more definite information concerning the acuteness
of hearing, one may have recourse to the 512 v. s. (vibrations per second) tuning fork

and the Politzer acoumeter.
For very young children, a fair idea of the hearing may be obtained by picking
out the backward or inattentive pupils and those that seem to watch the teacher's lips,
placing them with their backs to the examiner, and asking them to perform some un-
usual movement of the hand, or other act.
