diseases.  Bacteriology  is  likewise  now  an  established  adjunct  to 
the  work  of  the  chemist  and  analyst,  as  many  of  the  chemical 
problems  are  so  closely  interwoven  with  bacterial  study  that  a  work- 
ing knowledge  of  bacteriology  is  essential  for  the  chemist  who 
would  solve  these. 
The  specialist  in  bacteriology  may  have  access  to  the  voluminous 
studies  and  works  on  the  subject  and  to  the  extensive  current 
literature  relating  to  that  science,  but  the  busy  practitioner  of  medi- 
cine, the  pharmacist  and  the  chemist  a?  a  rule  can  devote  but  a 
moderate  amount  of  time  to  such  study.  The  book  now  before  us 
fills  in  an  excellent  manner  the  needs  of  these  busy  workers  for 
such  accurate,  up-to-date  information  on  bacteriology  as  is  es- 
sential to  their  needs. 
In  the  285  pages  with  tjie  46  illustrations  the  author  has  pre- 
sented a  concise  and  accurate  resume  of  bacteriology  as  relating  to 
medicine.  Despite  the  conciseness,  the  method  of  presentation  is 
clear  and  interesting. 
Part  I  of  the  book  entitled  "  Medical  Bacteriology  "  occupies 
171  pages.  Part  II,  "  Bacteriology,"  in  103  pages  discusses  a 
number  of  subjects  such  as  the  examinations  of  water,  milk  and 
eggs,  and  the  determination  of  the  germicidal  value  of  disinfectants 
which  might  be  considered  as  in  the  domain  of  technical  bacteriol- 
ogy and  in  other  chapters  considers  "  Diagnosis,"  "  Bacterial  Vac- 
cines," "  Therapeutic  Sera,"  "  The  Wassermann  Test "  and  "  Im- 
munity." The  differentiation  in  the  classification  of  these  subjects, 
which  certainly  are  medical,  is  not  clear  to  us. 
Of  the  49  short  chapters  included  in  Part  I,  42  of  these  are  de- 
voted to  the  individual  presentation  of  established  types  of  germs, 
as  for  example  Chapter  VII  deals  with  Staphylococci  and  Chapter 
VIII  with  Streptococci.  Each  chapter  sets  forth  in  paragraphs 
with  titles  in  boldfaced  type  the  subject  matter  clearly  and  this  is 
well  supplemented  by  the  illustrations. 
In  Chapter  II,  "  Classification,"  the  author  uses  the  terms 
"  higher  bacteria  "  and  "  higher  forms  of  bacteria "  for  organisms 
that  are  not  classified  as  "rod-shaped  Schizomycetes  "  {bacteria) 
or  even  as  belonging  to  the  Schizomycetes,  and  in  a  subsequent 
chapter  on  "  Staining "  names  as  Higher  Bacteria,  Leptothrices, 
Cladothrices,  Streptothrices,  Saccharomycetes  and  Hyphomycetes. 
The  author  has  thus  laid  the  foundation  for  his  treatment  in  sub-
