In  an  introductory  note  by  J.  T.  Hewitt  in  this  volume  it  is  stated 
that  "  in  the  course  of  the  past  century  the  study  of  organic  chemistry 
has  been  pursued  with  an  energy  which  has  not  been  exceeded  in 
any  department  of  science,  and,  by  sustained  effort,  not  only  has 
a  better  insight  been  obtained  into  processes  of  life,  but  many 
branches  of  industry  have  been  revolutionized."  The  student  of 
research  plays  an  important  part  in  the  development  of  science, 
but  it  is  very  fortunate  there  are  those  who  are  willing  to  take  the 
time  to  survey  the  field  of  research,  delve  into  the  published  papers 
and  after  assimilating  and  boiling  down  the  facts  give  us  the  fruits 
of  their  labors.  The  present  volume  is  one  of  these  indispensable 
books  that  is  stimulating  indeed.  How  inspiring  to  the  student  are 
the  words  of  Mr.  Hewitt  in  his  introduction  wherein  be  says :  "  Or- 
ganic chemists  have  achieved  much,  and  as  the  habit  of  simply  record- 
ing the  melting-points  and  analytical  data  of  new  compounds  dies  out, 
it  will  be  more  clearly  recognized  what  an  enormous  field  of  work  lies  • 
in  front  of  us." 
Among  the  subjects  considered  the  following  may  be  mentioned: 
the  polymethylenes ;  the  terpenes  and  camphors ;  the  uric  acid  or 
purine  group ;  the  alkaloids ;  the  relation  between  the  color  and 
constitution  of  chemical  compounds ;  salt  formation  of  pseudo-acids 
and  bases  ;  the  pyrones  ;  ketens,  ozomides,  triphenylmethyl ;  the  Grig- 
nard  reaction ;  etc.  H.  K.
