The  book  has  been  well  conceived  and  well  developed,  and  it 
will  not  only  be  found  useful  to  the  student,  but  also  of  special  value 
to  the  advanced  worker,  as  it  is  full  of  suggestions.  The  most 
important  laboratory  processes  which  have  been  worked  out  in  the 
development  of  organic  chemistry  are  considered.  The  directions 
are  full  and  accurate,  and  the  theoretical  explanations  of  the 
processes  are  clear  and  concise. 
In  addition  to  much  valuable  information,  as  found  in  the  chap- 
ters on  the  general  operations,  the  analysis  of  carbon  compounds, 
and  the  quahtative  examination  of  such  substances,  the  methods  for 
the  preparation  of  131  separate  compounds  are  given.  These  include 
hydrocarbons ;  alcohols  and  phenols ;  ethers ;  aldehydes,  ketones  and 
their  derivatives ;  acids ;  derivatives  of  acids ;  hydroxy  and  ketonic 
acids;  carbohydrates;  halogen  compounds;  nitro  compounds; 
amines ;  diazo,  hydrazo,  nitroso  and  other  nitrogen  compounds ;  and 
sulphur  compounds. 
While  this  book  has  been  prepared  especially  for  the  organic 
chemist,  it  will  be  found  of  very  great  service  to  the  manufacturing 
pharmacist.  Indeed,  the  pharmacist,  who  spends  some  of  his  time 
in  the  laboratory  will  be  stimulated  in  his  work,  and  will  be  well 
repaid  if  he  adds  to  his  desk  library  this  new  edition  of  Noyes's 
"  Organic  Chemistry  for  the  Laboratory."

This  is  the  eleventh  of  the  series  of  monographs  on  "  Biochem- 
istry "  edited  by  Drs.  Plimmer  and  Hopkins.  These  are  exceed- 
ingly valuable  books.  Each  monograph  has  been  prepared  by  a 
specialist,  and  contains  a  complete  bibliography.  The  contents  of 
the  present  volume  include:  (i)  the  fatty  acids,  glycerol  and  the 
glycerides,  other  alcohols  and  their  fatty  acid  esters,  phospholipines, 
galactolipines  and  lipines ;  (2)  the  extraction  of  fat,  and  the  estima- 
tion of  fat  in  animal  tissues;  (3)  physical  properties  of  fats,  general 
chemical  methods  used  in  analysis  of  fats,  separation,  identification 
and  constituents  of  fats : — fatty  acids,  alcohols  and  phospholipines ; 
(4)  the  physiology  of  fats :  biochemical  synthesis  of  fats  and  higher 
fatty  acids,  physiological  oxidation  of  fats  and  the  role  of  fats  in 
vital  phenomena.
