  tive 
  reactions 
  of 
  organic 
  compounds, 
  dealing 
  with 
  a 
  number 
  of 
  

   substances 
  important 
  in 
  medicine, 
  including 
  a 
  few 
  of 
  the 
  vegeta- 
  

   ble 
  alkaloids. 
  The 
  second 
  part 
  of 
  the 
  book 
  deals 
  with 
  volumetric 
  

   analysis 
  and 
  gives 
  a 
  number 
  of 
  important 
  methods. 
  The 
  last 
  

   part 
  takes 
  up 
  the 
  sanitary 
  examination 
  of 
  water, 
  the 
  detection 
  of 
  

   poisons, 
  and 
  blowpipe 
  analysis. 
  While 
  some 
  of 
  the 
  practical 
  

   parts 
  of 
  the 
  book 
  are 
  very 
  brief, 
  they 
  appear 
  to 
  be 
  well 
  adapted 
  

   to 
  the 
  purpose 
  of 
  serving 
  as 
  an 
  introduction 
  to 
  the 
  subjects. 
  It 
  

   would 
  seem 
  desirable 
  to 
  provide 
  this 
  class 
  of 
  students 
  with 
  some 
  

   practice 
  in 
  gravimetric 
  analysis, 
  which 
  is 
  not 
  included 
  in 
  this 
  

   book.

  — 
  The 
  fourth 
  edition 
  of 
  this 
  useful 
  manual 
  of 
  

   practical 
  physiological 
  chemistry 
  has 
  been 
  greatly 
  enlarged 
  by 
  

   the 
  addition 
  of 
  much 
  new 
  material 
  with 
  a 
  thorough 
  revision 
  of 
  

   the 
  old. 
  Its 
  usefulness 
  has 
  been 
  greatly 
  increased 
  by 
  the 
  addi- 
  

   tion 
  of 
  references 
  to 
  the 
  original 
  literature, 
  the 
  lack 
  of 
  which 
  in 
  

   previous 
  editions 
  has 
  limited 
  its 
  value 
  as 
  a 
  reference 
  book. 
  The 
  

   chapter 
  on 
  urine 
  analysis 
  contains 
  a 
  description 
  of 
  the 
  newer 
  

   methods 
  such 
  as 
  Van 
  Slyke's 
  amino 
  nitrogen 
  method, 
  and 
  the 
  

   microchemical 
  methods 
  of 
  Folin 
  and 
  his 
  coworkers 
  for 
  urea, 
  

   ammonia, 
  and 
  total 
  nitrogen. 
  To 
  the 
  chapter 
  on 
  enzymes 
  has 
  

   been 
  added 
  a 
  reference 
  table 
  of 
  enzymes, 
  their 
  classification 
  and 
  

   properties. 
  A 
  description 
  of 
  the 
  discovery, 
  optical 
  properties, 
  and 
  

   chief 
  source 
  of 
  the 
  amino 
  acids 
  occurring 
  in 
  proteins 
  in 
  tabular 
  

   form 
  has 
  been 
  added 
  to 
  the 
  chapter 
  on 
  proteins. 
  As 
  in 
  previous 
  

   editions, 
  the 
  excellent 
  illustrations 
  are 
  conspicuous. 
  The 
  book 
  

   as 
  a 
  whole 
  is 
  admirably 
  suited 
  " 
  for 
  use 
  in 
  courses 
  in 
  practical 
  

   physiological 
  chemistry 
  in 
  schools 
  of 
  medicine 
  and 
  science," 
  one- 
  

   half 
  of 
  the 
  contents 
  being 
  devoted 
  to 
  a 
  study 
  of 
  the 
  urine. 
  

  

  The 
  main 
  fault, 
  if 
  any, 
  in 
  this 
  manual 
  lies 
  in 
  too 
  great 
  a 
  wealth 
  

   of 
  material 
  rather 
  than 
  in 
  too 
  little. 
  In 
  the 
  description 
  of 
  many 
  

   of 
  the 
  various 
  qualitative 
  tests, 
  it 
  would 
  seem 
  that 
  some 
  selection 
  

   of 
  a 
  few 
  of 
  the 
  more 
  important 
  tests 
  from 
  among 
  the 
  many 
  

   described, 
  which 
  vary 
  only 
  in 
  some 
  slight 
  detail 
  from 
  each 
  other, 
  

   might 
  well 
  be 
  made. 
  The 
  detailed 
  description 
  of 
  some 
  of 
  the 
  

   less 
  important 
  determinations 
  such 
  as 
  the 
  determination 
  of 
  fecal 
  

   amylase 
  and 
  fecal 
  bacteria 
  should 
  be 
  relegated 
  to 
  more 
  complete 
  

   reference 
  manuals. 
  More 
  space 
  should 
  be 
  devoted 
  to 
  an 
  account 
  

   of 
  the 
  mode 
  of 
  origin 
  of 
  the 
  aporrhegmas 
  and 
  other 
  products 
  of 
  

   intestinal 
  putrefaction, 
  an 
  account 
  which 
  in 
  the 
  present 
  edition 
  is 
  

   limited 
  to 
  a 
  statement 
  of 
  their 
  primary 
  source, 
  proteins, 
  with 
  no 
  

   more 
  complete 
  explanation.
