of  carbon,  has  itself  only  12  eqs.  of  carbon,  it  cannot  contain  the
radical  benzoyle,  but  is  itself  a  new  radical,  derived  from  it  ;  just
as  acetyle,  derived  from  ethyle,  contains  2  eqs.  of  hydrogen  less
than  ethyle.  The  following  table  will  show  some  of  the  deriva-
tions of  benzole,  and  indicate  the  homologous  series  to  which
each  belongs.  Only  the  compounds  connected  with  benzole  are
here  named,  the  formulae  only  of  those  higher  in  the  series  being
given  :  —
