If  then  the  carbon  bands  are  a  part  of  the  coronal
spectrum,  they  were  not  visible  in  1886.  As
the  end  of  totality  approached,  Lieut.  Helby
placed  the  slit  radial  to  the  point  of  reappear-
ance of  the  photosphere ;  and  twenty  seconds
before  the  bright  edge  of  the  sun  peeped  out.
Father  Perry  reports  that  he  saw  about  fifty  lines
flash  into  view  in  the  limited  part  of  the  spectrum
under  observation.  "  This  lasted  only  a  very  short
time,  and  after  totality  no  lines  were  seen,  as  the
rising  wind  interfered  considerably  with  the  steadi-
ness of  the  telescope,  and  in  a  few  minutes  we
were  again  deluged  with  rain."  The  different
lensrths  of  the  bright  lines  seen  would  therefore
seem  to  lend  some  countenance  to  Mr.  Lockyer's
hypothesis,  but  is  it  not  possible  that  the  flash  just
after  totality  was  an  indication  of  the  "  reversing  "
layer?  However,  in  1882,  Mr.  Lockyer  himself  in
Egypt  took  some  observations  which  distinctly
corroborate  his  hypothesis,  and  the  observations
of  Mr.  Turner  in  the  eclipse  under  review  tell,
though  less  emphatically,  in  the  same  direction.
Thus  this  interesting  question  at  present  rests.
Two  days  after  the  eclipse.  Father  Perry  paid
a  farewell  visit  to  Canon  Petretto,  who  received
him  with  the  ringing  of  the  church  bells,  which
summoned  all  his  parishioners  to  the  church,  where
Father  Perry  was  forced  by  the  worthy  man  to
mount  the  pulpit,  and  give  them  a  final  discourse.
