“I  wish  you  to  put  under  every  letter  in  this  line  (pointing ­
  to  third  line)  the  letter  that  you  see  under  it  up  here
(pointing  to  first  two  key  lines).  Under  every  ‘b’  put  ‘f’
and  under  every  ‘1’  put  ‘w’  etc.  Now,  what  would  you  put
under  *r*  (pointing  to  the  first  letter  in  the  third  line)?
Finish  the  line.  Now  take  this  sheet  (giving  subject  test
proper)  and  do  the  same  thing,  taking  each  number  as  it
comes.  Do  this  quickly  and  carefully.  All  right?  Start.”
Allow  120  seconds.
Record:  Count  number  of  mistakes.  Record  number  of  test,
number  of  seconds  taken,  number  of  letters  covered,  and
