C h ap .  7 .     Saturn's  Satellites,        203

For,  in  the  firft  place,  inftead  of
four  Satellites  or  Moons,  as  Jupiter
hath,  Saturn  hath  five,  and  pro-
bably more.  Three  of  thefe  I  my
felf  have  feen  with  Mr.  Huygens's
1 2(5  foot  Glafs;  but  for  want  of  a
Pole  of  fufficient  height  to  mount
the  Glafs  high  enough,  I  am  not
fiire  I  have  feen  any  more.  And
befides  thofe  Five,  which  others
have  feen,  there  is  great  reafon  to
conclude  there  is  a  Sixth  lying  be-
tween the  two  Outermoft,  there  be-
ing a  larger  fpace  between  them
than  is  in  proportion  to  what  is
found  amongft  the  reft.  And  it  is
not  improbable  but  that  there  are  o-
thers  alfo  lying  beyond  the  Fifth,  or
Outermoft,  but  become  invifible  at
fo  great  a  diftance  from  us,  by  means
of  fome  obfcurity,  fuch  as  is  obferva-
ble  in  the  Outermoft  it  felf,  which
is  never  to  be  feen  by  us,  but  in  the

weftern


204  7he  Bulk  of     Book  VII.
weftern  part  of  its  Orbit,  as  Mr.  Hu'^'
gem  well  obferves  (a).
