separation  between  the  satellites,  and  therefore  with  this  instrument 
aud  power  first  contact  must  have  occurred  about  12’’02"'.  Definition 
is  very  bad,  however,  and  in  a larger  telescope  there  probably  might 
still  be  a smail  separation  between  the  limbs.

tracé  of  the  notches  is  apparent. 
12’’20™.  The  elongation  is  now  very  nearly  at  right  angles  to  the 
direction  of  the  motion  of  the  satellites,  and  is  so  slight  as  to  be 
scarcely  noticeable  in  this  bad  and  unsteady  definition.  I think  from 
the  smallness  of  the  elongation  that  nearly  half  satellite  I must  be 
concealed  behind  III.  In  this  bad  definition  it  is  not  possible  to  say 
which  satellite  is  in  front  of  the  other  from  the  appearance  al  one. 
Het  schrijven  van  den  heer  Stani.ey  Williams  bevatte  nog  de 
merkwaardige  mededeeling,  dat  ook  hij,  den  15  Juli  1902,  dezelfde 
conjunctie  had  waargenomen,  die  de  heer  Nijland  beschreven  had.  Zijn 
instrument  was  toen  een  G'/a  eng.  duims  reflector,  met  eene  vergrooting 
van  225  maal.  Ziehier  de  door  hem  medegedeelde  bijzonderheden  ;

one  will  occult  the  other.  See  diagram  m . 
13^52™.  The  satellites  form  one  disc,  which  has  the  slightest 
possible  elongation  in  a north  and  south  direction.  Owing  to  con- 
fused  seeing  this  disc  always  appeared  more  or  less  fuzzy,  and  it  is 
impossible  from  the  appearance  alone  to  say,  which  satellite  is  occul- 
ting  the  other.

14h04m  Satellites  clearly  separated.  The  occultation  must  have 
been  nearly  central.  II  is  a little  more  south  now  relative  to  III, 
than  it  was  before  occultation.  Possibly  the  slight  elongation  noted 
at  13''52'^  was  not  real. 
The  above  times  are  Greenwich  mean  times.  Satellite  III  was  on 
the  farther  side  of  its  orbit  moving  east,  II  on  the  near  side  moving 
west.  As  the  disc  of  III  is  larger  than  that  of  II,  the  phenomenon 
should  be  described  as  a transit  of  II  over  or  across  III,  rather  than 
an  occultation  of  one  satellite  by  the  other.
