circle.  Professor  Schimpfs  book  was  designed  for  the  use  of  pharma- 
cists and  pharmaceutical  students  and  that  is  one  of  the  reasons 
why  it  has  been  so  successful.  The  present  edition  differs  materially 
from  the  preceding  in  that  the  volumetric  analysis  of  the  alkaloidal 
drugs  are  considered  at  even  greater  length  than  heretofore.  Among 
the  newly  added  subjects  are  included  the  following :  Gordin  and 
Prescott's  Method  with  Wagner's  Reagent;  Gordin's  Modified 
Alkalimetric  Method  ;  Kebler's  General  Method  of  Extracting 
Alkaloids  from  Drugs;  A.  B.  Lyons'  Methods  for  the  Assay  of 
Vegetable  Drugs.  Assay  of  Galenical  Preparations,  Methods  of 
Lloyd,  Katz,  Kippenberger,  and  Farr  and  Wright. 
Detailed  methods  from  various  sources  are  given  tor  the  assay  of 
aconite,  belladonna,  cinchona,  coca,  colchicum,  hyoscyamus,  ipecac, 
nux  vomica,  opium,  strophanthus,  stramonium,  tobacco,  wild-cherry 
bark,  commercial  acetate  of  lime,  and  boric  acid. 
One  of  the  valuable  features  of  the  book  is  the  numerous  refer- 
ences to  original  literature.  The  value  of  the  book  would  be  en- 
hanced with  a  few  more  cross-references  to  authors  of  methods. 
For  those  of  our  readers  who  may  not  be  familiar  with  the  book 
it  should  be  stated  that  the  general  principles  underlying  volumetric 
analysis  are  considered,  together  with  the  kinds  of  apparatus  to  be 
employed  as  well  as  their  use.  There  are  also  considered  the  follow- 
ing subjects :  Indicators,  calculating  results,  analyses  by  neutraliza- 
tion, analyses  by  precipitation,  oxidimetry,  analysis  by  indirect 
oxidation,  estimation  of  substances  readily  reduced,  the  examination 
and  estimation  of  acetic  acid  and  acetates,  etc.,  as  well  as  the  sanitary 
analyses  and  volumetric  analysis  of  various  organic  substances,  as 
water,  milk,  butter,  air,  soap,  sugars,  pepsin,  peptone,  malt  prepara- 
tions, urine,  volumetric  assaying  of  vegetable  drugs,  assay  of  galeni- 
cal preparations,  etc. 
The  book  is  convenient  in  form  as  well  as  well  written,  and  will 
prove  valuable  to  the  progressive  pharmacist.
