A  Text-Book  of  Chemistry  Intended  for  the  Use  of  Pharma- 
ceutical and  Medical  Students.    By  Samuel  P.  Sadtler, 
Ph.D.,  LL.D.,  Virgil  Coblentz,  Ph.D.,  F.C.S.,  and  Jeannot

We  are  pleased  to  note  the  appearance  of  the  fifth  edition  of  this 
approved  text-book  of  chemistry  for  the  use  of  pharmacy  and  medi- 
cal students.     Throughout  this  revision  bears  testimony  to  the 
thoughtfulness  and  care  that  has  been  exercised  by  the  authors  in 
the  selection  from  the  broad  field  of  general  chemistry  of  those 
subjects  that  relate  especially  to  materia  medica  and  the  duties  of 
the  closely  allied  professions  of  medicine  and  pharmacy  in  the  dis- 
charge of  their  service  to  their  fellowmen.    The  changes  effected 
by  the  Ninth  Decennial  Revision  of  the  Pharmacopoeia  and  likewise 
the  newer  remedies  have  been  incorporated  in  the  revised  text. 
The  experience  of  the  authors  as  teachers  is  evidenced  by  the 
concise,  yet  clear,  methods  adopted  for  the  presentation  of  the 
numerous  rather  intricate  subjects  necessarily  included  in  a  text- 
book of  this  character  and  purpose.  The  scope  of  the  work,  while 
limited  to  the  needs  of  students  of  the  professions  it  is  intended  to 
serve,  nevertheless,  presents  the  subjects  of  general  chemistry  and 
the  physics  related  thereto,  sufficiently  in  detail  to  serve  as  the 
foundation  for  future  higher  study  in  special  fields  of  analytical 
and  research  work. 
The  typography,  printing  and  binding  are  excellent  and  the  illus- 
trations, while  not  profuse,  are  sufficient  and  very  well  demonstrate 
the  theories,  facts  and  methods  shown. 
The  contents  of  the  book  are  presented  in  four  divisions  of  the 
subject  matter,  Part  I  being  devoted  to  the  consideration  of  Ele-
