displacement  of  the  whole  mass 
of  water  from  North  to  South. 
At  50  meters  there  were  very 
slig-ht  velocities,  and  the  water 
flowed  chiefly  outwards.  At  100 
meters  the  velocities  were  greater, 
and  the  water  flowed  outwards 
incessantly.  Below  200  meters 
the  movement  was  extremely 
slight. 
So  few  ohservations  have  been 
made  in  the  Sondeleds  Fiord 
(near  Risor,  flg.  8),  that  we  can 
draw  no  deductions  other  than 
that  there  must  be  great  varia- 
tions  in  the  fiord.  It  is  however 
worth  noticing  that  even  at  a 
depth  of  20  meters  there  could 
be  occasionally  a very  strong  out- 
wai-d  stream. 
(2).  The  Banks  and  Edge  off 
Sondmore. 
On  the  Skrei  Banks  (St. 
299),  where  the  depth  was  70 
meters,  a series  of  ohservations 
were  tåken  during  two  tidal  peri- 
ods.  Owing  to  the  somewhat 
considerable  variations  in  the  di- 
i-ection  of  the  currents  it  has  been 
difflcnlt  here  too  to  follow  the 
movements  satisfactorily.  How- 
ever it  is  tolerably  clear  that 
there  were  two  diflei^ent  cun’ents 
over  the  bank:  one  in  the  up- 
per  2 0 meters  from  the  land, 
the  other  deeper  down  and
