ter  on  the  inner  morphology  of  the  higher  plants.  The  various  cell 
tissues,  the  cell  walls,  and  cell  contents  are  freely  shown  by  numerous 
line  drawings.  Pharmacists  should  be  more  familiar  with  this  sub- 
ject, and  the  time  is  coming  when  a  microscope  will  be  an  item  in 
the  equipment  of  every  pharmacy.^  Chapter  IV  treats  of  the  classi- 
fication of  Angiosperms  yielding  drugs,  food  products,  and  other 
economic  products  of  general  interest;  and  Chapter  V  is  devoted 
to  the  cultivation  of  medicinal  plants.  Much  must  be  done  in  this 
direction  in  the  near  future. 
Part  II  is  of  special  interest  to  pharmacists.  In  Chapter  I  all 
of  our  crude  drugs  are  carefully  considered,  and  all  allied  plants  are 
mentioned  showing  the  points  of  difference.  Crude  drugs,  micro- 
scopic sections,  tissue  elements,  crystals,  etc.,  are  fully  illustrated, 
and  the  descriptive  matter  carefully  written,  concise  and  complete. 
In  these  days  when  most  drugs  are  bought  in  powdered  or  ground 
condition,  the  pharmacist  should  be  able  to  determine  the  purity 
of  his  purchases.  He  may  become  able  to  do  this  by  careful  study 
of  Chapter  II  of  this  section.  Powdered  drugs  and  food  products 
are  here  grouped  according  to  the  cellular  tissues  present,  the  size 
and  character  of  the  starch  granules,  the  various  crystals,  etc. 
In  Part  III  the  reagents  necessary  for  microscopic  work  are 
presented,  and  microscopic  technic  discussed.  Part  IV  is  a  new 
section.  About  forty  pages  are  included,  treating  of  the  micro- 
analysis of  the  more  important  active  constituent  of  drugs.  This 
is  interesting  and  instructive  to  any  one  familiar  with  the  use  of 
the  petrographical  microscope. 
Professor  Kraemer  is  our  most  thorough  and  painstaking  inves- 
tigator in  this  department  of  study,  and  this  edition  shows  the  exact- 
ness of  detail  that  characterizes  his  work.  While  his  technical 
knowledge  is  the  highest,  his  writings  are  singularly  free  from 
burdensome  technicalities,  and  are  easily  understood  by  the  student. 
I  have  read  this  edition  with  much  pleasure  and  am  glad  to  give 
expression  of  my  appreciation  of  it.  C.  F.  Nixon. 
The  Pharmacopceia  and  the  Physician.  By  Robert  A. 
Hatcher,  M.D.,  and  Martin  I.  Wilbert,  Ph.M.  Third  revised  edi- 
tion.   Chicago  :  American  Medical  Association  Press,  1910. 
This  volume  consists  of  a  series  of  articles  which  originally 
appeared  in  the  Journal  of  the  American  Medical  Association,  dis- 
cussing the  chief  substances  in  the  United  States  Pharmacopceia, 
classifying  them  according  to  their  uses  and  describing  their  methods
