This  book  is  intended  to  be  a  laboratory  manual  on  organic  ma- 
teria medica  or  pharmacognosy.  The  book  is  divided  into  three 
parts.  Part  I  is  devoted  to  the  systematic  study  of  crude  drugs.  In 
Part  II,  one  hundred  pages  are  devoted  to  the  consideration  of  plant 
histology.  Part  III  is  given  to  "  chemic  exercises  in  materia 
medica." 
Part  I  differs  from  the  subject-matter  in  the  usual  books  on 
materia  medica  in  having  at  the  beginning  of  each  group  of  drugs 
an  outline  with  blanks  for  the  insertion  of  synonyms,  important  feat- 
ures in  description,  chief  constituents,  etc.  The  authors  say  in  their 
preface  that  the  laboratory  method  in  materia  medica  "had  never 
been  tried."  The  reviewer  might  say,  from  his  knowledge  of  the 
subject  as  taught  in  this  country  and  abroad,  that  he  is  not  aware 
that  it  is  being  taught  in  any  other  way  at  the  present  time.  The 
treatment  of  plant  histology  in  Part  II  resembles  that  in  other  books 
on  this  subject.  The  illustrations  are  chiefly  from  Godfrin  and 
Noel's  classical  work,  due  credit  being  given  to  these  authors.  In 
the  analytical  key  for  the  identification  of  an  unknown  powder,  the 
main  division  is  based  on  color,  the  sub-divisions  following  being 
based  on  taste  of  powder. 
Part  III  is  practically  a  chemical  plant  analysis.  Some  of  the 
work  outlined  by  the  authors  is  usually  carried  out  on  the  lecture 
table,  and  some  in  the  chemical  and  pharmaceutical  laboratories, 
where  it  probably  more  properly  belongs.  We  believe  that  micro- 
chemical  tests,  or  tests  for  quickly  determining  the  quality  of  com- 
mercial varieties  of  crude  and  powdered  drugs  alone,  should  be 
included  in  the  laboratory  courses  in  ateria  medica  and  pharmacog- 
nosy. If  the  chemical  and  pharmaceutical  laboratories  do  not  co- 
operate in  this  work,  then  it  is  important  that  provision  be  made  for 
it  in  the  laboratory  course  in  materia  medica  or  pharmacognosy. 
Leach,  in  his  recent  work  on  food  inspection  and  analysis,  shows 
the  close  relationship  of  analytical  and  biological  studies,  and  Tschirch 
in  the  publications  of  his  students  shows  the  interdependence  of 
pharmacognosy  and  plant  chemistry.  Dr.  Hatcher  and  Professor 
Sollmann  deserve  credit  for  the  careful  work  which  they  have  done 
in  the  preparation  of  this  book,  containing  as  it  does  a  large  amount 
of  useful  information.
