student.  The  consideration  of  the  material  is  in  systematic  manner, 
beginning  with  simple  materials  as  pollen  grains,  filamentous  algae, 
starch  grains,  leading  up  finally  to  the  more  intricate  work  in  cytology. 
This  is  as  it  should  be,  and,  really,  before  the  student  is  prepared  to 
study  in  detail  the  nucleus  he  should  have  a  pretty  thorough  train- 
ing in  the  more  apparent  products  of  the  cell  as  well  as  the  structure 
of  tissues.  Meyer's  book  is  without  question  among  the  best  for  the 
beginner  in  scientific  biology.  Its  value  is  increased  by  the  compre- 
hensive citation  to  the  literature. 
Allegemeine  Bakteriologie  und  Sterilisationslehre  fur  Arzte 
und  Pharmazeuten.  Yon  Dr.  K.  Laubenheimery  Universitat 
Heidelberg.  Jena:  Gustav  Fischer,  1915. 
A  most  excellent  book  on  the  methods  of  study  of  the  morphology 
and  biology  of  the  lower  microorganisms.  It  is  succinct,  yet  very 
comprehensive,  and  well  illustrated  with  five  plates  in  colors.  W  hile 
written  for  the  uses  of  physicians  and  pharmacists,  it  will  be  found 
useful  in  any  course  of  bacteriology.  The  work  is  divided  into  three 
parts.  In  Part  I  there  is  a  general  treatment  of  the  morphology  and 
biology  of  bacteria,  yeasts,  and  moulds  and  the  general  consideration 
of  their  chemistry  and  physiology,  together  with  the  discussion  of 
toxins,  infection,  immunity,  and  natural  resistance.  Here  also  are 
discussed  the  methods  of  serum  diagnosis,  and  there  is  an  excellent 
presentation  of  Ehrlich's  side-chain  theory.  In  Part  II  are  considered 
the  mechanical  and  optical  principles  of  the  microscope  and  its  use  in 
the  examination  of  bacteria  and  the  individual  study  of  them.  Part 
III  is  devoted  to  the  study  of  the  methods  of  sterilization  and  their 
application  to  practice.  Every  phase  of  bacteriological  work  is  con- 
sidered, and  we  have  not  seen  any  work  which  presents  the  subject  in 
such  a  clear  and  readable  manner  and  at  the  same  time  in  such  a 
broad  and  scientific  spirit.
