The  fact  that  it  has  become  necessary  so  soon  to  print  a  third 
edition  of  Professor  Henry  Kraemer's  "  Text-book  of  Botany  and 
Pharmacognosy  "  indicates  the  degree  of  approval  with  which  the 
second  edition  was  received.  The  latter,  which  made  its  appearance 
in  1907,  was  so  complete  and  comprehensive,  that  little  change  could 
be  made  in  the  text;  such  additions  have  been  made,  however,  as 
the  results  of  a  year's  research  made  possible  and  several  pages  have 
been  added  to  Part  III,  on  "  Reagents  and  Microscopical  Technic." 
The  most  notable  changes  are  to  be  found  in  the  illustrations.  In 
the  earlier  edition  some  of  the  half-tone  photographs  lacked  in  detail, 
having  something  of  a  silhouette  character.  These  have  been 
replaced  by  excellent  line  drawings,  that  show  to  perfection  both  the 
external  and  internal  structure  of  the  subjects.  Each  chapter  is 
profusely  illustrated,  over  300  plates  in  all,  including  about  50  new 
ones.   All  are  characterized  by  beauty  and  truthfulness  to  nature. 
Part  I  is  devoted  to  Botany  and  is  divided  into  five  chapters.  In 
Chapter  I,  plants  are  studied  in  their  great  groups,  in  sequence, 
from  the  Thallophytes  to  the  Angiosperms.  Chapter  II  treats  of 
the  "  Outer  Morphology  of  Angiosperms,"  Chapter  III  of  the 
"  Inner  Morphology  of  the  Higher  Plants,"  Chapter  IV  of  the 
botanical  classification  of  drugs  yielding  Angiosperms,  and  Chapter 
V  of  the  cultivation  of  medicinal  plants. 
Part  II  is  divided  into  two  chapters;  the  first  treats  of  crude 
drugs,  and  the  second  of  powdered  drugs  and  foods.  Part  III  con- 
sists of  valuable  data  relating  to  "  Reagents  and  Microscopical 
Technic." 
It  is  difficult  to  point  out  special  excellence  in  any  one  part,  as  each 
chapter  is  excellent  in  every  way;  in  detail,  clearness  and  concise- 
ness. The  work  has  a  unique  distinction  in  this  line  of  books,  in 
being  entirely  original,  and  the  author's  thorough  knowledge  of  his 
subject  is  shown  on  every  page.  C.  F.  Nixon.
