Essentials  of  Volumetric  Analysis.  An  introduction  to  the 
subject,  adapted  to  the  needs  of  students  of  pharmaceutical  chem- 
istry. Embracing  the  subjects  of  Alkalimetry,  Acidimetry,  Precipi- 
tation Analysis,  Oxidimetry,  Indirect  Oxidation,  Iodometry,  Assay 
Processes  for  Drugs,  Estimation  of  Alkaloids,  Carbolic  Acid,  Sugars, 
Theory,  Application  and  Description  of  Indicators.  By  Henry  W. 
Schimpf,  Ph.G.,  M.D.,  Professor  of  Analytical  Chemistry  in  che 
Brooklyn  College  of  Pharmacy.  Illustrated.  i2mo,  vii  -f  227  pages, 
38  figures.  Cloth,  $1.25.  New  York :  John  Wiley  &  Sons.  London: 
Chapman  &  Hall,  Limited.  1903. 
Volumetric  analysis,  like  the  study  of  organic  chemistry,  has  an 
unmistakable  charm  for  the  careful  student,  because  chemical  themes 
and  laws  are  continually  brought  into  play  and  accurate  results  are 
assured.  Trie  author  of  the  present  volume  has  made  an  excellent 
reputation  as  an  author  of  a  valuable  text-book  of  volumetric  anal- 
ysis and  the  present  work  has  apparently  been  prepared  to  popularize 
this  subject. 
The  subject-matter  is  systematically  arranged  as  far  as  can  be,  and 
treated  as  concisely  as  is  consistent  with  clearness  of  expression. 
The  processes  are  grouped  under  five  headings :  Neutralization, 
Precipitation,  Oxidation,  Indirect  Oxidation,  and  Iodometry.  The 
principles  underlying  each  group  are  definitely  indicated,  and  their 
application  illustrated  by  numerous  practical  examples.  Other  sub- 
jects treated  include  methods  of  calibration  and  of  the  accurate 
reading  of  graduated  instruments,  the  calculation  of  the  results  of 
analyses,  the  preparation  and  standardization  of  volumetric  solutions. 
The  indicators,  their  selection  for  special  cases  and  the  ionic  theory 
regarding  their  action,  as  well  as  assay  processes  for  phenol,  sugars 
and  vegetable  drugs,  also  receive  special  treatment. 
The  book  is  to  be  commended  to  students  and  others  interested 
in  volumetric  analysis  and  ought  to  be  in  the  hands  of  every  phar- 
macist in  the  United  States.  We  need  more  books  on  advanced 
pharmacy  which  are  written  as  clearly  as  this  one  and  with  so  much 
interest  and  profit  to  the  pharmacist.
