in  the  presence  of  serum.  Coliform  bacilli,  which  are  a  common 
infection  in  the  later  stages  of  wounds,  are  much  more  resistant  to 
the  action  of  the  antiseptic  in  test-tube  experiments  than  any  of  the 
other  types  of  organism  examined  in  this  way.  (H.  Drummond

BOOK  REVIEWS. 
Qualitative  Chemical  Analysis,  Henry  W.  Schimpf,  Ph.G., 
M.C.,  Professor  of  Analytical  Chemistry  in  the  Brooklyn  College  of 
Pharmacy.  Third  edition,  Revised,  ix  +  187  pages,  6X9-  Cloth, 
$1.50  net.    John  Wiley  and  Sons,  Inc.,  New  York,  1917. 
In  his  preface  the  author  states  that  he  is  "  encouraged  to  pub- 
lish a  new  and  revised  edition  "  because  of  the  "  exhaustion  of  the 
second  edition  of  this  book  and  the  greatly  increased  demand  for  it'* 
— a  statement  which  one  can  well  believe  after  having  examined  the 
book  even  only  superficially. 
The  subject  matter  is  considered  under  three  heads : 
Part    I.    Definitions  and  General  Considerations, 
Part  II.    Identification  and  Separation  of  Inorganic  Bases  and  Acids, 
Part  III.    Qualitative  Analysis  of  Organic  Substances. 
Part  I,  covering  16  pages,  gives  in  plain,  easily  understood,  lan- 
guage the  theoretical  information  that  the  student  most  needs  be- 
fore he  begins  the  actual  wrestle  in  the  laboratory  with  test-tube, 
filter,  funnel  and  reagent. 
Part  II  treats,  first,  of  the  use  of  apparatus  and  reagents,  theu 
takes  up  in  detail  the  metals  and  the  more  common  of  the  acids,  the 
student  being  taught  how  to  recognize  basic  and  acidic  constituents, 
first  of  simple  salts,  then  of  mixtures  o'f  salts.  The  reactions  are 
generally  illustrated  by  equations,  and  reasons  are  given  for  each 
step  in  any  process.  Numerous  charts  are  given,  generally  so 
plainly  worded  that  the  veriest  tyro  should  have  but  little  difficulty 
in  using  them  intelligently,  and  even  the  experienced  worker  should 
find  them  helpful. 
Part  III  treats,  first,  of  the  identification  of  the  constituent  ele- 
ments of  organic  substances,  then  takes  up  in  turn  the  use  of  im- 
miscible solvents,  use  of  Fehling's  solution,  detection  of  the  more
