such  a  character  and  so  arranged  as  to  constitute  very  easily  under- 
stood charts  of  the  activities  of  the  various  drugs. 
The  author  shows  a  very  thorough  knowledge  of  his  subject. 
Also,  he  appears  to  have  a  keen  appreciation  of  the  student's  needs 
and  of  the  student's  viewpoint.  This  is  a  commendable  combina- 
tion which  is  all  too  rare  among  teachers  of  technical  subjects.

"The  Microanalysis  of  Powdered  Vegetable  Drugs/'  By 
Albert  Schneider,  M.  D.,  Ph.  D.,  Professor  of  Pharmacog- 
nosy in  The  College  of  Pharmacy,  University  of  Nebraska. 
Second  edition,  Vol.  XII ;  548  pages  and  237  illustrations. 
Price,  $5.00.    P.  Blakiston's  Son  &  Co.,  Philadelphia. 
This  recent  publication  from  the  pen  of  Dr.  Schneider  repre- 
sents a  marked  improvement  over  the  first  edition,  which  appeared 
in  1902  under  the  title  of  "Powdered  Vegetable  Drugs."  Two  hun- 
dred and  twenty-five  pages  have  been  added  to  the  subject-matter 
appearing  in  the  first  edition;  some  of  the  old  figures  have  been 
replaced  by  newer  ones  and  a  number  of  new  illustrations  have 
been  added.  The  contents  are  included  in  eleven  chapters,  which 
are  as  follows :  The  Microscope  in  Modern  Pharmacy,  General  Sug- 
gestions on  the  Examination  of  Vegetable  Powders,  Quality  and 
Purity  of  Vegetable  Drugs  from  the  Standpoint  of  the  Pure  Drugs 
Act,  Causes  Modifying  the  Characteristics  of  Vegetable  Powders, 
Powdering  Vegetable  Drugs,  Adulteration  or  Sophistication  of 
Vegetable  Drugs,  The  Microscopical  Examination  of  Powdered 
Vegetable  Drugs,  Keys  to  the  Study  and  Identification  of  Simple 
Powdered  Vegetable  Drugs,  Keys  to  the  Study  and  Identification 
of  the  U.  S.  P.  and  N.  F.  Compound  Powders,  Microanalytical 
Study  of  Crystals,  Quantitative  Microscopic  Determinations. 
The  plan  of  the  work  is  excellent  and  permits  much  freedom 
of  initiative  to  teachers,  a  quality  often  wanting  in  many  of  our 
recent  scientific  texts.  There  is  sufficient  information  within  its 
covers  to  meet  the  requirements  of  a  two-semester  course  in  Pow- 
dered Vegetable  Drugs.  One  of  the  particular  outstanding  advan- 
tages is  the  large  number  of  illustrations  which  should  be  very 
helpful  to  all  who  use  it.  The  analytical  keys  are  workable  and 
should  be  welcomed  alike  by  drug  and  food  analysts.  As  a  ref- 
erence book  on  Powdered  Vegetable  Drugs  it  eclipses  in  data  any 
so  far  written  by  an  American  author.
