ing  with  the  general  principles  of  microscopy,  lichenology,  powdered 
drugs,  pharmaceutical  bacteriology,  and '  cultivation  of  medicinal 
plants.  This  new  book  strikes  in  a  new  field  and  will  be  much  ap- 
preciated by  his  colleagues.  It  is  primarily  intended  as  a  guide  to 
students  who  are  interested  in  the  bacteriological  examination  of 
foods  and  drugs.  Because  of  the  close  relationship  between  the 
work  of  the  bacteriologist  and  micro-analyst,  it  is  desirable  that 
wherever  possible  these  two  laboratory  branches  be  combined  in  the 
most  effectual  cooperative  manner.  The  volume  in  hand  is  divided 
into  two  parts,  the  one  giving  an  outline  of  micro-analytical  methods 
in  food  and  drug  laboratories,  and  the  second  giving  the  bacteriologi- 
cal methods  employed..  The  following  subjects  are  considered: 
Grouping  of  Substances  to  be  Examined  in  Food  and  Drug  Labora- 
tories ;  The  Work  of  the  Micro-analyst  in  Relationship  to  that  of  the 
Chemist  and  Bacteriologist ;  Equipment  for  Micro-analytical  Work ; 
Organoleptic  Testing ;  Methods  Useful  in  the  Examination  of  Vege- 
table Drugs,  Spices,  etc. ;  Methods  Useful  in  the  Examination  of 
Vegetable  Products ;  Micro-chemical  Color  Reaction  Tests ;  Mak- 
ing Analytical  Reports ;  The  More  Important  Histological  Elements 
of  Plants ;  Direct  Bacteriological  Examinations ;  Numerical  Limits 
of  Microorganisms  in  Foods  and  Drugs ;  Quantitative  Estimations 
by  the  Cultural  Methods ;  Preparation  of  Standard  Culture  Media ; 
General  Suggestions ;  Preparation  of  Required  Standard  Culture 
Media ;  Technic  for  Making  Quantitative  and  Qualitative  Estima- 
tions by  the  Plating  Methods ;  Practical  Application  of  the  Quanti- 
tative Estimations  by  the  Plating  Methods ;  Qualitative  Determina- 
tions ;  Evidence  of  Sewage  Contamination ;  Possible  Contamination 
of  Foods  with  the  Typhoid  Bacillus ;  Possible  Contamination  of 
Food  Substances  with  the  Cholera  Bacillus ;  Biological  Water 
Analysis ;  Bacteriological  Examination  of  Mineral  Waters ;  The 
Microscopical  and  Bacteriological  Examination  of  Milk;  The  Bac- 
teriological Examination  of  Shellfish ;  The  Bacteriological  and  Toxi- 
cological  Examination  of  Meats  and  Meat  Products ;  The  Bacterio-

Bacteriological  Examination  of  Fermented  Foods  and  Beverages ; 
Standardization  of  Disinfectants ;  Determining  the  Purity  and 
Quality  of  Sera,  Bacterins,  and  Related  Products ;  Special  Biological 
and  Toxicol ogical  Tests.
