  1. 
  Morphology 
  of 
  Invertebrate 
  Types; 
  by 
  Alexander 
  

   Petrttnkevitch. 
  Pp.

  figures. 
  New 
  York, 
  

   1916 
  (The 
  Macmillan 
  Company). 
  — 
  This 
  book 
  is 
  essentially 
  a 
  lab- 
  

   oratory 
  guide 
  to 
  the 
  dissection 
  of 
  the 
  principal 
  types 
  of 
  inverte- 
  

   brate 
  animals. 
  It 
  differs 
  in 
  important 
  respects 
  from 
  the 
  other 
  

   books 
  in 
  this 
  field, 
  particularly 
  in 
  insisting 
  upon 
  a 
  more 
  thorough 
  

   and 
  detailed 
  study 
  of 
  invertebrate 
  anatomy 
  than 
  has 
  hitherto 
  

   been 
  possible 
  for 
  any 
  except 
  the 
  most 
  advanced 
  students. 
  To 
  

   this 
  end 
  the 
  book 
  gives 
  explicit 
  directions 
  for 
  the 
  complete 
  dis- 
  

   section 
  and 
  study 
  of 
  all 
  the 
  organ 
  systems 
  of 
  the 
  animals 
  included 
  

   instead 
  of 
  a 
  few 
  superficial 
  structures. 
  Each 
  chapter 
  contains 
  a 
  

   brief 
  summary 
  of 
  the 
  anatomical 
  features 
  of 
  the 
  species 
  to 
  be 
  

   studied. 
  This 
  descriptive 
  part 
  explains 
  the 
  technical 
  terms 
  

   employed 
  and 
  is 
  accompanied 
  by 
  a 
  general 
  diagram 
  of 
  the 
  ani- 
  

   mal's 
  anatomy. 
  It 
  is 
  to 
  be 
  read 
  by 
  the 
  student 
  before 
  he 
  begins 
  

   the 
  laboratory 
  exercise. 
  There 
  are 
  also 
  brief 
  directions 
  for 
  

   obtaining 
  the 
  materials 
  required 
  and 
  for 
  preparing 
  them 
  for 
  

   study.

  — 
  As 
  in 
  the 
  first 
  edition 
  

   of 
  this 
  widely 
  adopted 
  text-book, 
  the 
  subject 
  matter 
  is 
  arranged 
  in 
  

   three 
  distinct 
  parts 
  : 
  I, 
  Morphology 
  and 
  Culture 
  of 
  Microorganisms, 
  

   includes 
  a 
  general 
  and 
  systematic 
  summary 
  of 
  the 
  structure 
  and 
  

   classification 
  of 
  molds, 
  yeasts, 
  bacteria 
  and 
  protozoa, 
  with 
  a 
  brief 
  

   account 
  of 
  the 
  invisible 
  microorganisms. 
  Part 
  II, 
  Physiology 
  of 
  

   Microorganisms, 
  contains 
  chapters 
  on 
  nutrition, 
  products 
  of 
  

   metabolism, 
  mechanism 
  of 
  metabolism, 
  and 
  the 
  influence 
  of 
  mois- 
  

   ture, 
  temperature, 
  light, 
  electricity 
  and 
  other 
  physical 
  and 
  chemi- 
  

   cal 
  conditions 
  on 
  the 
  life 
  of 
  the 
  organisms. 
  Part 
  III, 
  Applied 
  

   Microbiology, 
  is 
  subdivided 
  into 
  chapters 
  on 
  the 
  economic 
  import- 
  

   ance 
  of 
  the 
  microorganisms 
  of 
  soil, 
  water, 
  sewage, 
  milk 
  and 
  milk 
  

   products, 
  and 
  special 
  industries, 
  together 
  with 
  the 
  microbial 
  dis- 
  

   eases 
  of 
  plants, 
  insects, 
  domestic 
  animals 
  and 
  man, 
  and 
  the 
  

   methods 
  of 
  eontrol 
  of 
  infectious 
  diseases. 
  

  

  The 
  work 
  is 
  in 
  reality 
  more 
  than 
  a 
  text-book 
  ; 
  it 
  is 
  a 
  reliable 
  

   and 
  authoritative 
  summary 
  of 
  the 
  entire 
  knowledge 
  of 
  the 
  micro- 
  

   organisms 
  of 
  economic 
  importance. 
  It 
  is 
  the 
  combined 
  effort 
  of 
  

   many 
  specialists, 
  for 
  in 
  addition 
  to 
  the 
  able 
  work 
  of 
  the 
  editor, 
  

   the 
  different 
  features 
  of 
  the 
  subject 
  have 
  been 
  contributed 
  by 
  

   twenty-five 
  of 
  our 
  foremost 
  microbiologists.

   three

  on 
  the

  in 
  the 
  different 
  

   groups 
  of 
  vertebrates,
