**  I  never  knew  a  case  in  which  a  patient  was  relieved  of  a  genuine  tie  dotim-
reux  by  the  extraction  of  a  tooth  ^  and  I  remember  in  a  conversation  whidi  I  bad
with  an  experienced  dentist  some  years  ago,  that  he  told  me  that  he  had  very  fre-
quently been  called  upon  to  extract  teeth  on  these  occasions,  and  that  he  was  not
aware  that  the  operation  had  been  of  service  in  any  one  instance.'*  (p.  256.)

It  may  be  so  ;  yet  we  s^iould  consider  it  but  a  clumsy  practice  which
would  permit  diseased  and  useless  teeth  to  remain  in  the  head  of  a  patient
afflicted  with  tic  douloureux  of  the  face.
As  to  the  merits  of  the  "  operatiorC^  for  tic,  no  one  will  dispute  the
propriety  of  its  being  placed  in  the  following  position.
