  of 
  the

  — 
  Since 
  the 
  first 
  edition 
  of 
  this 
  work 
  appeared 
  (1903) 
  

   much 
  has 
  been 
  added 
  to 
  our 
  knowledge 
  of 
  bacteria 
  in 
  their 
  

   various 
  relationships. 
  The 
  new 
  edition 
  contains 
  a 
  great 
  deal 
  

   that 
  is 
  not 
  found 
  in 
  the 
  old. 
  This 
  is 
  most 
  apparent 
  in 
  the 
  

   description 
  of 
  methods 
  employed 
  in 
  serological 
  work. 
  Further- 
  

   more, 
  numerous 
  valuable 
  illustrations 
  have 
  been 
  added. 
  

  

  Bacterological 
  technique 
  is 
  new, 
  even 
  to 
  the 
  student 
  of 
  botany, 
  

   zoology 
  or 
  chemistry. 
  For 
  this 
  reason, 
  and 
  on 
  account 
  of 
  the 
  

   numerous 
  methods 
  involved, 
  it 
  is 
  necessary 
  for 
  the 
  student 
  to 
  

   receive 
  almost 
  constant 
  help 
  from 
  the 
  instructor, 
  or 
  with 
  the 
  aid 
  

   of 
  a 
  satisfactory 
  written 
  guide. 
  The 
  present 
  edition 
  is 
  compre- 
  

   hensive 
  and 
  clear. 
  The 
  subject 
  matter 
  is 
  divided 
  into 
  21 
  chapters, 
  

   altogether 
  covering 
  the 
  field 
  of 
  general 
  bacteriological 
  technique 
  

   admirably. 
  It 
  is 
  not 
  intended 
  so 
  much 
  for 
  advanced 
  students, 
  

   or 
  investigators, 
  as 
  for 
  those 
  who 
  are 
  endeavoring 
  to 
  acquire 
  a 
  

   general 
  thorough 
  knowledge 
  of 
  bacteriological 
  and 
  bio-chemical 
  

   technique 
  as 
  an 
  essential 
  in 
  the 
  study 
  of 
  bacteria 
  themselves. 
  

   The 
  book 
  is 
  planned 
  as 
  a 
  laboratory 
  guide 
  for 
  the 
  technical 
  

   student 
  generally, 
  whether 
  he 
  is 
  particularly 
  interested 
  in 
  pre- 
  

   ventative 
  or 
  curative 
  medicine, 
  brewing, 
  dairying 
  or 
  agriculture.

  Obituary. 
  

  

  Alfred 
  Russell 
  Wallace, 
  the 
  veteran 
  English 
  naturalist 
  

   and 
  traveler, 
  died 
  on 
  November 
  7 
  in 
  his 
  ninety-first 
  year. 
  His 
  

   contributions 
  to 
  science 
  were 
  numerous, 
  varied 
  and 
  of 
  the 
  first 
  

   importance, 
  but 
  his 
  name 
  will 
  be 
  chiefly 
  remembered 
  because 
  of 
  

   his 
  prominent 
  share 
  in 
  the 
  building 
  up 
  of 
  the 
  theory 
  of 
  evolution. 
  

  

  Sir 
  William 
  Henry 
  Preece, 
  who 
  contributed 
  largely 
  to 
  the 
  

   development 
  of 
  the 
  telegraph 
  and 
  telephone 
  in 
  Great 
  "Britain, 
  

   died 
  on 
  November 
  6 
  in 
  his 
  eightieth 
  year.
