The  monographs  of  the  different  drugs  are  very  complete  and 
while  one  does  find  a  number  of  omissions,  as  for  instance  under 
Glycyrrhiza,  in  the  enumeration  of  other  plants  containing  glycyr- 
rhizin,  this  is  rather  to  be  expected,  as  the  task  undertaken  by 
Tschirch  is  almost  superhuman. 
The  amount  of  information  collated  of  each  drug,  the  nearly 
complete  citation  of  the  literature,  and  the  numerous  excellent  illus- 
trations make  this  work  indispensable  to  both  the  pharmacist  and 
pharmacologist.

skopischen  Analyse  der  Drogenpulver.  Erster  Band.  I  Lieferung. 
Yon  Dr.  Ludwig  Koch,  Universitat  Heidelberg.  Leipzig:  Verlag 
von  gebriider  Borntraeger,  1909. 
In  this  part  of  Koch's  ex:ellent  Atlas  we  find  microscopic  descrip- 
tions of  the  following  barks  :  Cascarilla,  red  cinchona,  and  cinnamon. 
The  illustrations  are  well  drawn  and  quite  accurate.  Pharmacists, 
and  particularly  pharmacognosists,  are  indebted  to  Dr.  Koch  for 
giving  us  such  a  painstaking  and  valuable  work.

The  Eclectic  Alkaloids,  Resins,  Resinoids,  Oleoresins,  and 
Concentrated  Principles.  By  John  Uri  Lloyd.  Bulletin  of  the 
Lloyd  Library,  No.  12.  Pharmacy  Series,  No.  2,  1910.  Cincinnati: 
J.  U.  and  C.  G.  Lloyd. 
This  is  a  very  valuable  publication,  and  there  is  probably  no  one 
living  who  could  present  in  such  a  concise  and  illuminating  manner 
the  history  of  the  "  Concentration  feature  of  the  American  Materia 
Medica  "  as  the  author.  He  says  :  "  It  will  be  perceived  that  the  so- 
called  eclectic  resinoids.  alkaloids,  and  resins  were  introduced  into 
the  passing  along  of  the  science  of  pharmacy,  materia  medica,  and 
medicine  of  the  nineteenth  century,  much  as  a  foreign  body,  for  a 
temporary  purpose,  becomes  a  part  of  a  structure  from  which  it  is 
afterwards  excised,  leaving  in  the  end  a  few  remnants  only  to  tell 
the  story  of  its  former  usefulness.  It  is  as  the  superstructure  to  a 
bridge  that,  supporting  the  incomplete  edifice,  is  vital  to  its  very 
construction,  but  yet  is  finally  torn  away  by  its  own  builders." 
In  the  present  volume  are  excellent  portraits  and  brief  biog- 
raphies of  John  King,  William  Stanley  Merrell,  Alexander  Wilder,
