  These 
  two 
  Banks-Island 
  skulls 
  are 
  of 
  great 
  interest, 
  as 
  showing 
  

   a 
  distinct 
  tendency 
  towards 
  (probably 
  a 
  youthful 
  stage 
  of) 
  the 
  arti- 
  

   ficial 
  deformity 
  noticed 
  in 
  the 
  MallicoUo 
  skulls, 
  and 
  hitherto 
  sup- 
  

   posed 
  to 
  be 
  peculiar 
  to 
  the 
  natives 
  of 
  that 
  island. 
  The 
  present 
  

   specimens, 
  however, 
  prove 
  that 
  the 
  flattening 
  process 
  is 
  also 
  prac- 
  

   tised 
  to 
  a 
  certain 
  extent 
  in 
  the 
  neighbouring 
  island 
  of 
  Merilava.
