  — 
  

   Professor 
  Ganong's 
  book 
  occupies 
  a 
  unique 
  field 
  among 
  botanical 
  

   text-books 
  and 
  is 
  addressed 
  to 
  teachers 
  of 
  botany 
  rather 
  than 
  to 
  

   their 
  pupils. 
  It 
  is 
  full 
  of 
  the 
  most 
  helpful 
  directions 
  and 
  sug- 
  

   gestions 
  and 
  sets 
  forth 
  clearly 
  the 
  aims 
  of 
  modern 
  botanical 
  

   teaching. 
  The 
  first 
  part 
  is 
  taken 
  up 
  with 
  eight 
  " 
  essays 
  on 
  

   botanical 
  pedagogics," 
  and 
  the 
  following 
  are 
  among 
  the 
  topics 
  

   discussed 
  : 
  things 
  essential 
  to 
  good 
  botanical 
  teaching, 
  botanical 
  

   laboratories, 
  collections 
  and 
  books, 
  scientific 
  drawing 
  and 
  descrip- 
  

   tion, 
  common 
  botanical 
  errors. 
  In 
  the 
  second 
  part, 
  an 
  elementary 
  

   course 
  in 
  botany 
  is 
  described, 
  which 
  is 
  arranged 
  with 
  reference 
  

   to 
  the 
  principles 
  emphasized 
  in 
  the 
  first 
  part. 
  The 
  topics 
  are 
  

   carefully 
  selected, 
  so 
  as 
  to 
  illustrate 
  clearly 
  and 
  connectedly 
  the 
  

   "most 
  vital 
  and 
  illuminating" 
  facts 
  of 
  botany 
  and 
  at 
  the 
  same 
  

   time 
  to 
  draw 
  out 
  " 
  most 
  quickly 
  and 
  thoroughly 
  " 
  the 
  student's 
  

   faculties. 
  The 
  essentials 
  of 
  anatomy, 
  morphology, 
  physiology 
  

   and 
  ecology 
  are 
  taught 
  from 
  flowering 
  plants, 
  as 
  it 
  is 
  deemed 
  

   advisable 
  to 
  begin 
  with 
  objects 
  more 
  or 
  less 
  familiar 
  to 
  the 
  stu- 
  

   dent, 
  and 
  the 
  course 
  is 
  concluded 
  with 
  a 
  short 
  and 
  general 
  survey 
  

   of 
  the 
  vegetable 
  kingdom, 
  beginning 
  with 
  the 
  Algae 
  and 
  ending 
  

   with 
  the 
  angiosperms. 
  The 
  book 
  is 
  particularly 
  welcome 
  at 
  the 
  

   present 
  time 
  when 
  the 
  teaching 
  of 
  botany 
  is 
  in 
  a 
  somewhat 
  

   unsettled 
  state. 
  It 
  is 
  to 
  be 
  recommended 
  not 
  only 
  to 
  teachers 
  of 
  

   the 
  science 
  but 
  also 
  to 
  those 
  persons 
  who 
  still 
  consider 
  the 
  study 
  

   of 
  botany 
  as 
  synonymous 
  with 
  the 
  analysis 
  of 
  flowers,

  of

  — 
  The 
  science 
  of 
  evo- 
  

   lution 
  has 
  so 
  often 
  been 
  treated 
  from 
  a 
  zoological 
  standpoint 
  that 
  

   its 
  principles 
  are 
  fairly 
  well 
  understood. 
  The 
  present 
  account, 
  

   however, 
  although 
  taken 
  up 
  with 
  topics 
  more 
  or 
  less 
  familiar 
  to 
  

   the 
  botanist, 
  fills 
  a 
  gap 
  in 
  biological 
  literature, 
  by 
  presenting 
  the 
  

   subject 
  of 
  plant 
  evolution 
  in 
  a 
  clear 
  and 
  connected 
  manner. 
  The 
  

   two 
  introductory 
  chapters 
  describe 
  briefly 
  the 
  important 
  facts 
  in 
  

   regard 
  to 
  the 
  anatomy 
  and 
  physiology 
  of 
  plants 
  and 
  the 
  external 
  

   conditions 
  under 
  which 
  they 
  grow. 
  The 
  study 
  of 
  plant 
  evolution 
  

   then 
  begins 
  with 
  a 
  discussion 
  of 
  the 
  " 
  simplest 
  forms 
  of 
  life," 
  in- 
  

   cluding 
  the 
  slime-molds, 
  the 
  bacteria, 
  the 
  Cyanophyceae 
  and 
  cer- 
  

   tain 
  of 
  the 
  unicellular 
  green 
  Algae. 
  This 
  is 
  followed 
  by 
  chapters 
  

   on 
  the 
  other 
  Algae, 
  the 
  Fungi, 
  the 
  bryophytes, 
  the 
  pteridophytes, 
  

   the 
  gvmnosperms 
  and 
  the 
  two 
  classes 
  of 
  angiosperms. 
  At 
  all 
  

   points 
  the 
  interrelationships 
  of 
  the 
  types 
  selected 
  are 
  emphasized,
