ence  easy  and  convenient.  In  order  to  meet  the  difficulty  which  ia  pre- 
sented by  this  arrangement  to  those  who  are  accustomed  to  a  nosological 
arrangement,  an  Index  of  Diseases  has  been  introduced,  in  which  refer- 
ence is  made  to  the  name  and  page  of  all  substances  used  in  each  disease. 
It  will  be  found  that  the  author  has  judiciously  gone  more  into  details 
in  the  important  articles,  such  as  quinia,  chloroform,  opium,  rhubarb,  ol. 
terebinthina,  etc.  He  has  given  copious  references  to  the  authors  from 
whom  he  quotes,  but  in  many  instances  it  is  to  be  regretted  the  articles 
indicate  an  imperfect  acquaintance  with  American  medical  authorities, — a 
fact  not  surprising,  as  his  first  edition  was  written  in  the  East  Indies.  For 
this  reason,  the  valuable  properties  of  many  useful  American  drugs  are 
wholly  unnoticed,  among  which  may  be  mentioned  wild  cherry  bark,  ul- 
mus,  cornus  florida,  gillenia,  geranium,  gossypii  radix,  monarda,  stillin- 
gia,  hydrastis,  cypripedium,  gelsemium,  symplocarpus,  etc.  It  will  be 
also  observed  that  iEther  is  noticed  with  half  a  page  of  comment,  whilst 
chloroform  occupies  twelve  pages  !  thus  showing  how  the  stand-point  and 
circumstances  that  surround  a  writer  influence  his  writings.  Dr.  Waring, 
aiming,  as  he  evidently  does,  to  embrace  a  wide  range  of  non-officinal 
remedies,  would  do  well  to  consult  more  American  authors  before  he  issues 
another  edition. 
The  second  part  of  the  book  refers  to  medicinal  agencies  and  therapeutic 
classes,  as  alteratives,  anaesthetics,  hot  and  cold  baths,  blood-letting, 
electricity,  inhalation,  etc. 
The  book  is  beautifully  gotten  up  by  the  publishers,  and  is  certainly  one 
of  the  most  valuable  additions  to  a  medical  library  that  has  been  published 
of  late  years. 
Synopsis  of  the  various  courses  of  practical  instruction  pursued  in  the  School 
of  Analytical  and  Applied  Chemistry  in  the  University  of  Michigan.  By 
Silas  H.  Douglass,  M.A.,  M.D.,  Prof,  of  Chemistry.    Ann  Arbor,  1866. 
This  department  of  the  extensive  educational  operations  of  the  Univer- 
sity of  Michigan  is  under  the  direction  of  Prof.  Silas  H.  Douglass  and  his 
assistants,  and  embraces  courses  on  qualitative  analysis,  determinative 
mineralogy,  quantitative  analysis,  metallurgy  and  assaying,  toxicology,  urin- 
alysis and  practical  pharmacy. 
"  The  first  of  these  courses  is  required  of  all  students  entering  the 
laboratory  ;  and  to  be  admitted  to  it  the  student  must  pass  a  satisfactory 
examination  in  elementary  chemistry."  Hence  the  object  of  this  course 
is  to  familiarize  the  student  practically  with  the  subject  he  has  been 
merely  studying  in  books,  and  requires  him  to  examine  qualitatively  one 
hundred  compounds.  The  other  courses  can  be  chosen  from  as  to  which 
will  be  pursued  afterwards.  In  the  quantitative  course  fifty  separate 
operations  are  carried  out,  including  the  analysis  of  salts,  minerals,  alloys, 
ashes,  soils  and  mineral  waters.    Alkalimetry,  aciditnetry,  chlorimetry,
