  In 
  1882 
  one 
  of 
  us 
  made 
  a 
  list 
  of 
  the 
  contents 
  of 
  the 
  parts 
  of 
  

   Chenu 
  from 
  a 
  copy 
  then 
  existing 
  in 
  the 
  British 
  Museum, 
  while 
  in 
  

   1909 
  the 
  other 
  was 
  indebted 
  to 
  Messrs. 
  Wheldon 
  for 
  a 
  sight 
  of 
  

   a 
  second 
  copy 
  in 
  which 
  vols. 
  1-3 
  were 
  in 
  paper 
  covers 
  and 
  vol. 
  4 
  

   in 
  original 
  parts. 
  This 
  material, 
  together 
  with 
  a 
  number 
  of 
  other 
  

   notes, 
  now 
  enables 
  us 
  to 
  give 
  a 
  definite 
  collation 
  and 
  series 
  of 
  dates 
  

   for 
  Chenu's 
  work. 
  

  

  The 
  dates 
  of 
  receipt 
  of 
  tlie 
  parts 
  at 
  the 
  British 
  Museum 
  and 
  their 
  

   contents 
  will 
  be 
  found 
  in 
  the 
  front 
  of 
  the 
  following 
  table, 
  while 
  the 
  

   date 
  in 
  black 
  figures 
  at 
  the 
  end 
  of 
  each 
  paragraph 
  indicates 
  the 
  date 
  

   of 
  publication 
  as 
  deduced 
  from 
  all 
  the 
  evidence 
  before 
  us.
