Italian  custom  of  castrating  boys  to  preserve  their  youthful
singing  voices  bears  witness  to  the  close  connection  between
the  voice  and  the  organs  of  sex.  Delaunay  remarks  that  while
a  bass  need  not  fear  any  kind  of  sexual  or  other  excess  so  far
as  his  voice  is  concerned,  a  tenor  must  be  extremely  careful
and  temperate.  Among  prostitutes,  it  may  be  added,  the  evo-
lution of  the  voice  and  of  the  larynx  tends  to  take  a  masculine
direction.  This  fact,  which  is  fairly  obvious,  has  been  accurately
investigated  at  Genoa  by  Professor  Masini,  who  find  that
among  50  prostitutes  zg  showed  in  a  high  degree  the  deep
masculine  voice,  while  the  larynx  was  large  and  the  vocal  cords
resembled  those  of  man ;  only  6  out  of  the  50  showed  a  normal
larynx;  while  of  20  presumably  honest  women  only  2  showed
the  ample  masculine  larynx.  {Archivio  di  Psichiatria,  vol.  xiv.,
