10  AN  INTRODUCTION  TO  PRACTICAL  PHARMACY. 
AN  INTRODUCTION  TO  PRACTICAL  PHARMACY,  designed  as  a 
Text-book  for  the  Student,  and  a  guide  to  the  Physician  and  Pharma- 
'   ceutist.    With  many  formulas  and  prescriptions.    By  Edward  Parrish, 
&c,  with  234  Illustrations.    Philadelphia :  Blanchard  &  Lea. 
This  book  was  noticed  briefly  in  the  last  number  of  this 
journal  by  the  editor.    We  purpose,  at  present,  to  consider  it 
somewhat  more  in  detail,  and  to  present  such  extracts  from  it 
as  will  show  its  general  scope  and  character. 
It  is  not  based  on  the  superstructure  of  any  foreign  publication, 
as  has  usually  been  the  case  with  books,  on  similar  subjects, 
issued  from  the  American  press,  but  is  original  in  conception 
with  its  author,  who,  from  his  experience  both  as  a  pharmaceutist 
and  as  a  lecturer  and  teacher  of  practical  pharmacy  to  medical 
students,  has  become  aware  of  the  want  of  a  text-book  in  this 
department,  which  he  has  thus  endeavored  to  supply. 
It  contains  instruction  for  the  inexperienced 
student  and  apprentice,  of  a  practical  kind, 
commencing  with  the  "rudiments,"  given  in  an 
easy  conversational  style,  sometimes  with  rather 
an  amusing  degree  of  minuteness,  (ex.  gr.  p.  80 
on  folding  filters,  p.  499,  on  powders,)  exempli- 
fied with  many  wood  cuts,  of  which  the  one  an- 
nexed is  a  favorable  specimen.  The  officinal  pre- 
parations are  arranged  in  groups,  under  the  ap- 
propriate classes,  in  a  way  that  effects  a  great 
saving  of  space,  giving  at  the  same  time  a 
clear  view  of  their  composition.  To  show  his 
method  of  doing  this,  we  quote  the  syllabus  of 
the  medicated  waters  : —
