one  to  recognize  all  of  the  important  drugs,  spices,  etc. ;  their  com- 
mon adulterants  and  the  quality  as  well.  While  each  chapter  is  fully 
illustrated,  in  no  part  of  the  work  will  the  illustrations  be  of  more 
service  than  those  found  in  this  chapter.  It  is  difficult  to  teach  or 
to  study  microscopic  material  from  descriptive  matter  only.  Perfect 
reproductions  are  here  given  of  all  characteristic  elements  found  in 
the  powders  studied. 
In  these  days  of  drug  and  food  inspection,  this  chapter  will  be  of 
great  service.  I  know  of  no  American  work  in  which  is  to  be  found 
so  much  carefully  prepared  matter  on  this  subject. 
In  Part  III  is  given  a  list  of  reagents,  and  directions  for  preparing, 
staining  and  mounting  of  powders  and  microscopic  sections. 
This  work  of  Professor  Kraemer's  is  a  valuable  addition  to  the 
scientific  knowledge  of  the  subjects  treated,  and  the  author  has 
reason  to  feel  great  satisfaction  with  the  result  of  his  labor.

The  Dispensatory  of  the  United  States  of  America.  Nine- 
teenth edition,  thoroughly  revised,  largely  rewritten,  and  based  upon 
the  Eighth  Decennial  Revision  of  the  United  States  Pharmacopoeia. 
By  H.  C.  Wood,  M.D.,  LL.D.;  Joseph  P.  Remington,  Ph.M.,  F.C.S., 
and  Samuel  P.  Saddler,  Ph.D.,  LL.D.,  assisted  by  Albert  B.  Lyons, 
M.D.,  and  Horatio  C.  Wood,  Jr.,  M.D.  Sheep  ;  octavo  ;  2008  pages  ; 
$8.    Philadelphia :  J.  B.  Lippincott  Company.  1907. 
This  new  edition  of  the  United  States  Dispensatory  is  the  product 
of  three  men  who  have  had  an  unusually  long  experience  in  editing 
encyclopedic  works  of  this  character,  and  who,  in  procuring  the 
assistance  of  two  well-known  investigators  and  authors,  have  shown 
that  they  recognize  the  present-day  difficulties  in  writing  sucn  a 
stupendous  and  authoritative  work  without  competent  assistance. 
The  present  edition  is  practically  a  new  book.  It  has  been 
entirely  rewritten,  and  the  reading  matter  is  arranged  in  double 
columns.  Probably  the  desirability  of  separating  official  from 
unofficial  substances,  as  has  been  the  custom  of  the  authors  of  this 
work,  was  never  more  appreciated  than  at  the  present  time,  when 
the  standards  for  the  official  substances  are  recognized  by  the 
national  Food  and  Drugs  Act.  Another  desirable  feature  of  the 
book  is  the  increase  in  the  matter  containing  quotations  with  refer- 
ences to  literature,  in  conjunction  with  the  abstracts,  thus  enabling 
the  reader  to  refer  to  the  original  papers.  This  will  be  much  appre- 
ciated by  investigators  and  others  as  well.
