Qualitative  Chemical  Analysis.  A  guide  in  the  practical  study  of  chemistry  and  in 
the  work  of  analysis.  By  Silas  H.  Douglas,  Professor  of  Chemical  Technology 
and  Metallurgy,  and  Albert  B.  Prescott,  Professor  of  Organic  Chemistry  and 
Pharmacy  in  the  University  of  Michigan.  Second  edition,  revised.  New  York  : 
D.  Van  Nostrand,  1876.    8vo,  pp.  254. 
Although  the  work  is  intended  tor  the  more  advanced  student,  who  has  already 
studied  chemistry  theoretically,  the  preliminary  chapters  contain  brief  explanations 
concerning  chemical  notation  and  the  various  operations  performed  in  analytical 
work.  This  is  followed  by  the  analytical  reactions  of  the  metals,  divided  as  usual 
into  groups,  and  of  the  inorganic  and  of  the  commoner  organic  acids.  The 
reactions  given  are  not  merely  those  which  are  necessary  for  the  performance  of 
ordinary  qualitative  analysis,  but  it  has  been  the  authors'  aim  to  give  as  complete  a 
picture  of  the  behavior  of  the  various  substances  as  the  present  state  of  science  will 
permit,  for  the  purpose  of  making  it  available  for  recognition  and  separation  under 
the  most  varied  circumstances.  The  tables  of  comparison,  which  are  introduced  to 
take  a  bird's-eye  view  of  the  resemblance  and  differences  of  tne  behavior  of  allied 
metals  and  acids,  will  be  found  very  convenient  and  instructive.  The  book  closes 
with  chapters  on  analysis  in  the  dry  way,  on  the  systematic  analysis  of  solutions  and 
the  solubilities  of  salts,  and  with  an  enumeration  of  the  reagents  used  in  analysis. 
The  authors  say  that  the  chief  object  in  this  work  has  been  "  to  aid  the  student 
in  gaining  an  accurate  acquaintance  with  the  facts  whereby  analyses  are  made,  and 
a  clear  understanding  of  the  co-ordination  of  these  facts — the  principles  of  analysis." 
In  our  opinion,  the  work  is  well  calculated  for  this  purpose,  and  it  cannot  fail, 
wnen  properly  used,  "  to  prevent  habits  of  automatic  operation  and  of  superficial 
knowledge  in  analysis/'  We  recommend  it  to  pharmacists  and  others  as  a  work  of 
reference  in  the  performance  of  analytical  work. 
The  United  States  Pharmacopoeia  and  the  American  Medical  Association.  Svo,  pp.  11. 
This  pamphlet,  by  Prof.  H.  C.  Wood  of  the  University  of  Pennsylvania,  opposes 
the  position  in  regard  lo  the  national  "  Pharmacopoeia,"  as  taken  by  Dr.  Squibb  in 
the  pamphlet  noticed  on  page  143  of  our  last  number,  and,  like  the  latter,  merits 
the  careful  attention  of  all  the  medical  and  pharmaceutical  bodies  of  the  United 
States. 
The  People  ~js.  Schrumpf.  Misdemeanor :  Adulteration  of  Milk.  Argument  of 
W.  P.  Prentice,  counsel  to  the  Board  of  Health  for  the  prosecution.  New  York  1 
1877.    Svo,  pp.  32. 
A  few  months  ago  this  case  attracted  considerable  attention,  and  was  freely  dis- 
cussed by  the  daily  papers.  The  pamphlet  before  us  is  an  able  review  of  the  testi- 
mony on  both  sides,  and  more  particularly  of  that  portion  which  relates  to  the 
detection  of  watered  milk  by  mean's  of  the  lactometer,  which  Prof.  Doremus  had 
asserted  was  unreliable.    The  accused  was  found  guilty. 
Report  on  the  Salt  Manufacture  of  Michigan.  Prepared  to  accompjany  volume  III 
of  the  State  Geological  Survey.  By  S.  S.  Garrigues,  Ph.D.,  State  Salt  Inspector. 
New  York:  Julius  Bien,  1876  pp.  52. 
An  interesting  report  on  the  manufacture  of  salt,  entering  into  details  concerning- 
apparatus,  process,  inspection  and  yield,  and  giving  also  historical  notes  and  statist- 
ical information.
