Incompatibilities  in  Prescriptions.  For  Students  in  Phar- 
macy and  Medicine  and  Practicing  Pharmacists  and  Physicians. 
By  Edsel  A.  Ruddiman,  Ph.M.,  M.D.  Fourth  edition,  thoroughly 
revised.  New  York :  John  Wiley  &  Sons,  Inc. ;  London :  Chapman 
&  Hall,  Limited.  1917. 
Dr.  Ruddiman's  work  is  very  well  known  and  has  met  with  great 
success.  The  subject  is  one  of  a  fundamental  character  and  Dr. 
Ruddiman  has  handled  it  very  aptly.  The  arrangement  is  very  ex- 
cellent, so  that  when  one  meets  with  incompatibilities  in  prescrip- 
tions he  can  usually  determine  the  nature  of  it,  and  provide  a  rem- 
edy. In  the  fourth  edition  a  number  of  new  remedies  have  been 
included  and  a  number  of  prescriptions  have  been  increased. 
The  table  in  previous  editions,  giving  the  average  price  charged 
for  prescriptions  has,  through  the  courtesy  of  the  editor  of  the 
N.  A.  R.  D.  Journal,  been  replaced  by  the  schedule  adopted  by  the 
National  Association  of  Retail  Druggists.

The  author  of  this  compact  and  handy  little  volume  is  the  best 
known  writer  on  subjects  connected  with  the  soda  fountain  in  Amer- 
ica. He  says  in  his  preface :  "  The  time  has  come  when  a  book 
is  needed  which  the  dispenser  can  carry  in  his  pocket  so  that  he  may 
have  instant  access  to  simple  directions  for  preparing  hundreds  of 
sundaes.  There  are  so  many  he  cannot  possibly  carry  them  in  his 
head.  The  traveler  from  another  city  steps  to  the  counter  and  asks 
if  a  sundae  popular  in  his  city  is  served.  Often  all  the  necessary 
ingredients  are  at' the  dispenser's  disposal,  but  he  is  compelled  to  say 
'  No,'  when  a  glance  into  a  pocket  guide  would  enable  him  to  prepare 
it,  and  thus  give  greater  satisfaction  to  the  customer.  Again,  this 
is  the  day  of  new  things.  People  like  something  a  little  different 
and  many  dispensers  like  to  put  something  new  on  their  menus  as  a 
special  every  day  or  every  week.    This  guide  will  give  a  new  for-
