  In 
  1872 
  his 
  sight 
  partially 
  failed 
  him 
  through 
  exces:sive 
  

   use 
  of 
  the 
  microscope 
  in 
  the 
  examination 
  of 
  Orthotricha, 
  

   The 
  next 
  year 
  his 
  friend 
  Sullivant 
  died. 
  At 
  this 
  time 
  the 
  

   two 
  were 
  preparing 
  for 
  the 
  publication 
  of 
  a 
  manual 
  of 
  mosses 
  

   of 
  North 
  America. 
  The 
  loss 
  of 
  sight 
  and 
  the 
  loss 
  of 
  the 
  

   principal 
  in 
  the 
  movement 
  well-uigh 
  stopped 
  the 
  production 
  

   of 
  the 
  book, 
  and 
  probably 
  would 
  have 
  done 
  so 
  had 
  not 
  inter- 
  

   ested 
  friends 
  urged 
  its 
  completion. 
  Lesquereux 
  therefore 
  

   called 
  in 
  the 
  aid 
  of 
  Mr. 
  Thomas 
  P. 
  James, 
  and 
  vmder 
  his 
  

   hand 
  was 
  continued 
  most 
  of 
  the 
  microscopic 
  work. 
  While 
  

   this 
  was 
  doing 
  Lesquereux 
  prepared 
  the 
  larger 
  part 
  of 
  the 
  

   letter-press 
  of 
  the 
  Supplement 
  to 
  the 
  Icones 
  Muscorum 
  of 
  

   Sullivant 
  from 
  the 
  notes 
  left 
  by 
  the 
  latter 
  in 
  his 
  herbarium 
  ; 
  

   but 
  firmly 
  declined 
  to 
  have 
  his 
  name 
  appear 
  on 
  the 
  title 
  page 
  

   of 
  the 
  work. 
  In 
  1879, 
  with 
  James, 
  he 
  published 
  in 
  the 
  

   Proc. 
  Amer. 
  Acad. 
  (xiv. 
  133-141) 
  descriptions 
  of 
  a 
  number 
  

   of 
  new 
  species 
  of 
  mosses. 
  In 
  1882 
  James 
  suddenly 
  died, 
  

   and 
  again 
  the 
  long-expected 
  manual 
  seemed 
  blocked. 
  On 
  

   account 
  of 
  failing 
  health 
  Lesquereux 
  was 
  unable 
  to 
  press 
  the 
  

   work 
  to 
  completion 
  and 
  a 
  large 
  share 
  of 
  the 
  editorial 
  work 
  

  

  Watson. 
  The 
  work 
  appeared 
  in 
  

   1884. 
  ^* 
  

  

  From 
  this 
  time 
  Les<jueYe\ix 
  wholly 
  gaVe 
  up 
  his 
  bryology 
  

   ical 
  studies. 
  His 
  bryological 
  books, 
  herbarium 
  and 
  manu- 
  

   script 
  notes 
  on 
  all 
  the 
  mosses 
  he 
  had 
  examined 
  were 
  pre- 
  

   sented 
  to 
  the 
  Museum 
  at 
  Neuchatel, 
  a 
  gain 
  to 
  that 
  institution 
  

   not 
  at 
  all 
  commensurate 
  viiih 
  the 
  loss 
  to 
  this 
  country. 
  

   ^ 
  Lesquereux 
  was 
  quite 
  coi^scious 
  of 
  his 
  failing 
  powers, 
  and 
  

   It 
  was 
  often 
  put 
  to 
  his 
  friends 
  in 
  a 
  very 
  pathetic 
  way 
  in 
  his 
  

   letters. 
  _ 
  In 
  1886 
  he 
  wrote 
  in 
  response 
  to 
  some 
  expression 
  

   about 
  his 
  welfare 
  : 
  «' 
  Allow 
  me 
  to 
  thank 
  you 
  for 
  your 
  inter- 
  

   est 
  m 
  my 
  health. 
  I 
  have 
  an 
  incurable 
  sickness—old 
  age. 
  I 
  

   can 
  still 
  work 
  on 
  fossil 
  botany, 
  but 
  can 
  not 
  do 
  much." 
  About 
  

   tvvo 
  years 
  ago 
  he 
  suffered 
  a 
  stroke 
  of 
  paralysis, 
  which 
  gradu- 
  

   ally 
  increased 
  m 
  extent 
  Yintil 
  death 
  came 
  to 
  his 
  release.
