Whys  in  Pharmacy. — A  compilation  of  reasons  underlying  the 
principles  of  pharmacy,  supplemented  by  a  table  of  equations.  By 
Edsel  A.  Ruddiman.  i2mo,  vi-l-196  pages.  Cloth,  $1.00.  New 
York:  John  Wiley  &  Sons;  London:  Chapman  &  Hall,  Ltd. 
In  the  preface  of  Dr.  Ruddiman's  book  the  reasons  for  its  publi- 
cation are  given  as  follows  : 
"  In  the  publication  of  these  questions  and  answers  the  writer 
claims  no  originality.  The  only  reason  he  has  for  putting  them 
into  book  form  is  because  he  has  had  numerous  requests  for  them 
from  his  students  and  the  readers  of  the  Bulletin  of  Pharmacy  in 
which  much  of  the  matter  has  been  printed. 
"  Early  in  the  course  of  the  author's  teaching  he  came  to  the  con- 
clusion that  the  teaching  of  the  reasons  for  the  use  of  certain  ingre- 
dients and  for  mixing  these  in  certain  orders  is  one  of  the  most 
important  parts  of  the  work — more  essential  than  the  memorizing 
of  formulas.  The  book  is  not  intended  as  a  quiz  compend,  but  as 
an  aid  to  those  who  wish  to  get  at  the  principles  underlying  the 
subject.  At  first  only  the  questions  were  written,  leaving  the  stu- 
dent to  look  up  the  answers  for  himself.  Mr.  Joseph  Helfman, 
editor  of  the  Bulletin  of  Pharmacy,  suggested  that  more  good  would 
be  done  the  readers  by  giving  the  answers  as  well,  and  the  writer 
came  to  the  same  conclusion." 
The  following  subjects  are  considered  :  (1)  Preparations:  Waters, 
cerates,  papers,  collodions,  decoctions,  elixirs,  plasters,  emulsions, 
percolation  and  fluid  extracts,  solid  extracts,  glycerites,  infusions,
