ing  the  B.  P.  description,  the  author  discusses  prominent  character- 
istic features  and  the  analytical  standards  suggested,  supplementing 
the  latter  with  tables  showing  the  results  by  various  investigators. 
Citations  to  important  literature  are  given  in  connection  with  the 
various  subjects  taken  up. 
In  addition  to  the  drugs  and  preparations  of  the  British  Pharma- 
copoeia, the  work  is  devoted  to  the  consideration  of  various  foods,  as 
butter,  coffee,  flour,  ice-cream  and  ices,  infant  foods,  jam,  meat 
preparations,  preservatives,  vinegar,  aerated  water,  etc.  In  the  treat- 
ment of  these  subjects,  as  of  drugs,  the  author  has  shown  good 
judgment  and  his  suggestions  are  particularly  valuable. 
There  are  a  number  of  works  treating  of  analytical  methods  and 
which  contain  the  results  of  analyses,  but  this  work  is  unique  and 
supplies  a  most  important  want  in  the  correlation  of  the  works  of 
various  investigators,  together  with  a  discussion  of  the  standards 
suggested. 
Notes  on  Pharmacognosy.  Second  edition,  revised  and  enlarged 
by  Otto  A.  Wail,  Ph.G.,  M.D.  St.  Louis :  Aug.  Gast  Bank  Note 
and  Litho.  Company,  1902. 
The  author  states  in  his  preface  that  "  these  notes  are  intended 
to  take  the  place  of  notes  which  a  diligent  student  might  possibly 
write  down  for  himself,  so  that  during  lectures  he  can  give  undi- 
vided attention  to  the  words  of  the  leccurer  and  to  the  illustrations 
and  specimens  shown."  The  author  further  states  that  "  these 
notes  serve  as  a  skeleton  of  the  science  of  pharmacognosy,  present- 
ing only  those  main  facts  which  a  student  should  make  an  effort  to 
remember."  "  The  system  adopted  is  based  on  the  general  princi- 
ples of  modern  pharmacognosy  as  established  and  first  published  in 
Europe  by  Schleiden  and  Berg,  and  in  this  country  by  Maisch,  but 
in  many  details  the  arrangement  is  original." 
After  a  general  consideration  of  the  subject  the  author  gives  an 
outline  of  the  classification  of  drugs  according  to  physical  character, 
istics  and,  beginning  with  animal  drugs,  he  proceeds  to  the  consid- 
eration of  various  cryptograms,  then  to  roots,  etc.,  until  finally  vari- 
ous constituents,  as  acids,  juices,  extracts,  etc.,  are  taken  up,  In  the 
introduction  to  vegetable  drugs  the  author  considers  some  of  the 
principles  underlying  botany  and  microscopical  technique.  A  large 
number  of  illustrations  are  distributed  throughout  the  text,  and 
these  are  largely  the  work  of  the  author.
