the  use  of  students  of  pharmacy,  as  a  reference  book  for  pharmacists, 
and  as  a  hand-book  for  the  food  and  drug  analyst.  By  Henry 
Kraemer,  Ph.B.,  Ph.D.,  the  Philadelphia  College  of  Pharmacy.

Fourth  edition,  revised  and  enlarged.  Philadelphia  and  London : 
J.  B.  Lippincott  Company. 
The  fourth  edition  of  Professor  Henry  Kraemer's  "  Text-Book 
of  Botany  and  Pharmacognosy  "  which  has  just  appeared  from  the 
press  is  printed  on  excellent,  heavy  paper,  with  clear,  easily*  readable 
type,  is  well  bound,  and  is  a  fine  appearing  book.  Like  its  predeces- 
sors it  is  profusely  illustrated  with  half-tone  photographs  and  line 
drawings.  While  in  former  editions  the  illustrations  have  been 
excellent,  a  number  of  improvements  have  been  made,  so  that  all 
seem  perfect  in  every  detail.  In  no  other  book  extant  is  more 
care  given  to  every  detail. 
The  work  is  the  most  comprehensive  now  in  print,  and  too  much 
cannot  be  said  in  praise  of  this  latest  product  of  Prof.  Kraemer's 
life-work. 
The  work  is  divided  into  four  parts.  Part  I  is  given  to  botany 
and  consists  of  five  chapters.  Chapter  I  will  be  read  with  interest 
by  every  student  of  botany.  The  text  and  illustrations  carry  one 
along  to  a  true  conception  of  the  evolution  in  plant  life.  In  Chap- 
ter II,  roots,  stems,  fruits,  etc.,  are  studied  in  classes,  with  reference 
to  their  "  Outer  Morphology."    Chapter  III  is  an  exhaustive  chap-
