This  scheme  has  been  sanctioned  by  the  French  government,  and  the 
Paris  committee  are  preparing  the  rules  and  programme  of  the  Congress, 
which  they  promise  to  communicate  as  soon  as  determined  on.  In  the 
meantime  we  cheerfully  comply  with  the  request  made  to  us,  to  make

Our  Exchanges. — Our  Southern  exchanges  are  slowly  coming  back 
again.  The  Atlanta  Medical  and  Surgical  Journal,  the  Nashville  Medi- 
cal Journal,  the  Savannah  Journal  of  Medicine,  and  the  New  Orleans

Elements  of  Medical  Chemistry.  By  B.  Howard  Rand,  M.D.,  Professor 
of  Chemistry  in  Jefferson  Medical  College,  Philadelphia.  T.  Ellwood 
Zell  &  Co.,  1867  :  pp.  399,  12mo. 
This  work  has  been  arranged  by  the  author  as  a  text  book  for  medical 
students,  and  he  regards  it  as  equivalent  to  a  full  set  of  notes  to  his  course 
on  chemistry  in  Jefferson  Medical  College.  Aware  of  the  "immense  ex. 
tent  of  the  subjects  comprised  under  the  general  head  of  chemistry  and 
physics,"  he  has,  by  a  careful  selection,  made  the  effort  to  embrace  so 
much  of  the  topics  in  this  small  volume  as  shall  be  most  useful  to  the 
student  in  grasping  the  subject  within  the  limited  time  he  has  to  devote 
to  it  among  his  numerous  studies,  expecting  the  more  extended  writers  to 
be  resorted  to  when  time  and  opportunity  favor  it.  The  term*-"  medical" 
chemistry  is  used  to  convey  the  idea  that  in  his  selections  and  explana- 
tions the  author  has  had  in  view  the  uses  which  the  physician  makes  of 
chemistry,  and  has  dwelt  more  pointedly  on  such  portions  as  bear  on  his 
specialities. 
The  author  very  properly  urges  a  rigid  adherence  to  the  processes  of 
the  U.  S.  Pharmacopoeia,  and  in  using  officinal  titles  for  preparations, 
gives  those  of  the  Pharmacopoeia  when  included  in  that  work.  The 
universal  use  of  symbols  to  designate  chemical  composition,  and  the  ne- 
cessity of  understanding  them  in  order  to  comprehend  the  text  books  and 
journals,  has  induced  Dr.  Rand  to  give  special  attention  to  the  elucidation 
of  symbols  and  nomenclature.  The  preparation  and  use  of  antidotes,  and 
tests  for  poisons,  has  received  due  attention. 
The  publisher  has  done  his  part  well,  the  type  being  clear  and  the 
paper  good.    Price,  $6.00.
