The  work  is  bound  with  an  alphabetical  table  of  cases  that  will 
prove  useful  to  all  lawyers  having  pharmaceutical  clients. 
Taken  in  its  entirety  as  an  example  of  industry  in  an  untilled 
field,  there  is  small  reason  for  the  modest  plea  of  the  author  in 
the  preface,  "  that  those  who  examine  its  contents  will  do  so  with 
such  indulgence  as  may  seem  due  to  the  work  as  a  pioneer  in  its 
peculiar  field."  W.  L.  Cliffe. 
Text-book  of  Organic  Chemistry.  By  Henry  Leffmann,  A.M., 
M.D.,  and  Charles  H.  LaWall,  Ph.G.  Philadelphia:  P.  Blakiston's 
Son  &  Co.     1904.    Pp.  231. 
This  little  book  is  stated  in  the  preface  to  be  offered  as  an  aid  to 
the  study  of  organic  chemistry  in  connection  with  general  and  pro- 
fessional courses. 
The  subject  of  organic  chemistry,  whether  considered  from  the 
purely  scientific  side  or  from  the  points  of  view  of  its  technical  appli- 
cation and  its  bearing  on  medicine  and  pharmacy,  has  grown  to 
such  dimensions  that  it  is  a  matter  of  difficulty  to  know  what  to 
select  for  discussion.  Whether  a  book  of  such  limited  size  shall 
endeavor  merely  to  serve  as  an  introduction  to  the  understanding 
of  the  field,  or  whether  it  shall  endeavor  to  give  descriptions  and 
details  as  to  any  considerable  number  of  compounds,  is  the  question 
for  decision.  Remsen's  well-known  little  book  on  Organic  Chem- 
istry is  specifically  an  introduction  to  the  subject,  and  mentions  a 
limited  number  of  compounds,  with  little  descriptive  matter ;  this 
book  devotes  48  pages  to  the  principles  of  organic  chemistry  and 
166  pages  to  descriptive  chemistry. 
The  section  on  the  principles  is  in  general  well  stated,  but,  being 
put  compactly  together,  before  any  illustrative  account  of  special 
compounds  appears,  is  liable  to  lead  to  an  attempt  at  memorizing 
work  so  well  known  and  deplored  by  the  teacher  of  chemistry. 
Pages  47  and  48  are  specially  noted  as  likely  to  encourage  this  kind 
of  study. 
The  descriptive  section,  beginning  on  page  49,  is,  however,  very 
clearly  and  interestingly  written  and  conveys  much  information  of 
value  to  the  medical  or  pharmaceutical  student.  The  numbered 
experiments  following  each  section  are  well  chosen  and  very  help- 
ful to  the  student  who  will  carry  them  through.  Attention  is  called, 
for  example,  to  the  experiments  on  pages  no  and  n  1  following
