This  gives  us  a  new  division  of  Genus  and
Species  respectively.  We  have  first  of  all  a  Genus
which  can  never  be  a  Species ;  last  of  all  a  Species
which  can  never  be  a  Genus,  and  between  the  two
a  number  of  classes  accommodating  enough  to  be
one  or  the  other,  as  need  shall  require.
(a)  The   Summum    Genus    is    the    highest    and
largest  class  of  all,  the   first   breaking   up   of   the
Transcendental  and  all-embracing  concept  of  Being.
(b)  The  Infima  Species  is  the  lowest  and  smallest
class,  the  last  Universal,  the  smallest  collection  of
individual  objects.
(c)  Subordinate,  or  Subaltern,  or  Intermediate  classes
are    respectively   genera    or    species,   according  as
we  consider  them  in  relation  to  the  smaller  classes
below  them,  or  the  larger  classes  above  them.     In
relation  to  the  former  they  are  genera ;  in  relation
to  the  latter  they  are  species.     Genera  with  regard
to  those  below  them ;  species  with  regard  to  those
above  them.     Thus  animal  is  a  genus  as  compared
with  man,  a  species  as  compared  with  beings  that  live.
Mammals  is  a  genus  in  regard  to  seals,  a  species  at
compared   with   animals.      Jewels   is   a  genus    with
regard  to  diamonds,  a  species  with  regard  to  stonest
or  to  things  without  life.
