inorganic  and  organic,  illustrated  by  numerous  practical  examples. 
This  part  has  included  many  valuable  methods,  such  as  the  electro, 
lytic  methods  for  several  of  the  metals,  silver,  gold  and  lead  assays, 
calorimetric  value  of  coals,  and  analyses  of  milk,  butter,  spirits, 
sugar,  tea,  tanning  materials,  and  soaps. 
Part  V  is  devoted  to  gas  analysis,  and  includes  the  Hemfel 
methods,  the  use  of  Lunge's  nitrometer,  and  methods  of  vapor  den- 
sity determinations. 
The  last  thirty-four  pages  (Part  VI)  give  the  results  of  a  number 
of  typical  analyses  in  tabular  form,  and  a  series  of  tables  of  useful 
constants  for  reference. 
The  book  is,  as  before  stated,  a  very  convenient  and  compact  ref- 
erence book  to  turn  to  in  connection  with  the  instruction  of  a  labo- 
ratory teacher,  and  will  undoubtedly  be  of  a  useful  character.

Incompatibilities  in  Prescriptions.  By  Edsel  A.  Ruddiman. 
Second  Edition,  Rewritten.  8vo.  312  pages.  Cloth,  $2.00. 
New  York  :  John  Wiley  &  Sons.  London:  Chapman  &  Hall,  Lim- 
ited. 1900. 
The  book  is  divided  into  two  parts.  Part  I  treats  of  Incompati- 
bilities and  Part  II  treats  of  Prescriptions  with  Criticisms.  Part  I 
has  been  entirely  rewritten.  The  substances  treated  are  arranged 
in  alphabetical  order  according  to  their  Latin  names  and  the  text  is 
replete  with  information  concerning  the  subject  of  Incompatibilities. 
Over  300  prescriptions  are  given  with  criticisms.  A  table  of  solu- 
bilities has  been  added.  A  complete  index  of  prescriptions  is  given 
which  will  enable  any  one  to  find  at  a  glance  any  prescription  con- 
taining a  certain  ingredient  or  combination  of  ingredients  that  are 
likely  to  be  encountered  in  practice.  Taking  the  book  as  a  whole, 
while  it  may  seem  intended  primarily  for  students  in  pharmacy  and 
medicine,  it  is  one  that  the  practicing  pharmacist  will  find  of  service, 
as  it  contains  much  valuable  information  and  many  practical  hints.
