  vol-

  and

  (1892 
  and

  — 
  Professor 
  Frank's 
  text- 
  

   book 
  follows 
  the 
  usual 
  course 
  of 
  treatment, 
  but 
  gives 
  ^reat 
  

   prominence 
  to 
  the 
  subject 
  of 
  physiology. 
  This 
  part 
  of 
  his 
  work 
  

   makes 
  the 
  treatise 
  ot 
  great 
  value. 
  The 
  topics 
  are 
  fully 
  treated 
  

   and 
  the 
  essential 
  matters 
  are 
  kept 
  in 
  their 
  proper 
  relations, 
  so 
  

   that 
  the 
  general 
  result 
  is 
  symmetrical. 
  The 
  questions 
  with 
  which 
  

   Prof 
  essor 
  Frank 
  has 
  specially 
  busied 
  himself 
  in 
  his 
  original 
  work, 
  

   are 
  discussed 
  in 
  an 
  exceedingly 
  interesting 
  manner 
  and 
  with 
  due 
  

   perspective. 
  In 
  a 
  few 
  instances, 
  it 
  seems 
  on 
  the 
  first 
  reading, 
  as 
  

   if 
  the 
  author 
  had 
  stated 
  some 
  of 
  his 
  own 
  conclusions 
  in 
  too 
  posi- 
  

   tive 
  a 
  form 
  for 
  the 
  requirements 
  of 
  a 
  text-book 
  for 
  the 
  general 
  

   student, 
  but, 
  as 
  above 
  said, 
  the 
  treatise 
  is 
  symmetrical,

  Lehrbuch

  K.

  — 
  The 
  author 
  has 
  prepared 
  this 
  text-book 
  with 
  

   reference 
  to 
  the 
  needs 
  of 
  students 
  who 
  are 
  reviewing 
  their 
  work 
  

   before 
  examination. 
  It 
  is, 
  therefore, 
  a 
  comprehensive 
  volume 
  in 
  

   which, 
  the 
  whole 
  ground 
  is 
  covered 
  in 
  such 
  a 
  manner 
  as 
  to 
  refresh 
  

   one's 
  memory 
  with 
  regard 
  to 
  the 
  results 
  of 
  personal 
  laboratory 
  

   exercises 
  in 
  histology 
  and 
  physiology, 
  supplementing 
  this 
  by 
  

   sufficiently 
  full 
  treatment 
  of 
  systematic 
  and 
  economic 
  botany. 
  

   The 
  newer 
  results 
  have 
  been 
  incorporated 
  with 
  the 
  older 
  in 
  a 
  

   well-proportioned 
  and 
  well-balanced 
  manner, 
  so 
  that 
  the 
  work 
  

   gives 
  a 
  clear 
  and 
  sound 
  exposition 
  of 
  the 
  present 
  state 
  of 
  our 
  

   knowledge. 
  The 
  author 
  has 
  carried 
  his 
  work 
  on 
  under 
  the 
  advice 
  

   and 
  with 
  the 
  assistance 
  of 
  Dr. 
  Goebel, 
  Professor 
  of 
  Botany 
  in 
  

   Munich.

   — 
  This 
  is 
  the 
  ninth 
  edition 
  of 
  Prantl's 
  well-known 
  work, 
  already 
  

   noticed 
  in 
  this 
  Journal. 
  The 
  revision 
  has 
  been 
  thorough. 
  In 
  the 
  

   histological 
  and 
  physiological 
  portions 
  changes 
  demanded 
  by 
  

   recent 
  investigations 
  have 
  been 
  made, 
  and 
  important 
  modifica- 
  

   tions 
  have 
  been 
  made 
  throughout 
  the 
  systematic 
  part. 
  It 
  may 
  be 
  

   remembered 
  that 
  the 
  earlier 
  editions 
  gave 
  a 
  good 
  deal 
  of 
  promi- 
  

   nence 
  to 
  species 
  : 
  in 
  this 
  edition, 
  only 
  those 
  are 
  referred 
  to 
  which 
  

   are 
  of 
  interest 
  in 
  economic 
  botany, 
  especially 
  in 
  medicine. 
  The 
  

   number 
  of 
  illustrations 
  has 
  been 
  increased 
  from 
  326 
  to 
  355. 
  The 
  

   improvement 
  in 
  the 
  engravings 
  since 
  the 
  first 
  edition 
  has 
  been 
  

   very 
  great.

  — 
  Professors 
  Strasburger 
  and 
  Schimper 
  with 
  the 
  two 
  Privat- 
  

   docents 
  associated 
  with 
  them 
  in 
  botanical 
  teaching 
  in 
  Bonn, 
  have 
  

   carried 
  successfully 
  to 
  completion 
  the 
  very 
  hazardous 
  experiment 
  

   ol 
  preparing 
  a 
  composite 
  text-book. 
  The 
  dangers 
  which 
  con- 
  

   front 
  such 
  an 
  undertaking 
  are 
  obvious. 
  Each 
  specialist 
  is 
  likely 
  

   as 
  we 
  say 
  to 
  magnify 
  his 
  office, 
  and 
  give 
  a 
  disproportionate 
  

   amount 
  ol 
  space 
  to 
  the 
  results 
  which 
  have 
  been 
  recently 
  attained
