It  will  be  seen  that  this  handbook  is  not  only  a  technology,  but 
also  an  analytical  industrial  organic  chemistry.  The  manner  of 
treatment  of  the  industries  considered  is  clear,  concise  and  from  the 
point  of  view  of  one  having  a  large  amount  of  practical  experience. 
There  are  126  illustrations  and  16  diagrams  showing  outlines  of 
processes  employed  in  the  different  industries.  The  book  is  not 
only  valuable  from  the  standpoint  of  the  manufacturer  and  chemist, 
but  is  equally  valuable  as  a  text-book  for  universities  and  schools  of 
technology  where  industrial  organic  chemistry  is  being  taught. 
The  present  revised  edition  has  been  brought  up  to  date  by  the 
incorporation  of  the  results  of  progress  in  the  different  industries 
during  the  past  five  years.  Some  of  the  chapters,  in  fact,  as  those  on 
the  natural  and  artificial  dye  colors,  have  been  largely  rewritten. 
The  progress  in  the  applied  sciences  is  so  remarkable  that  books 
become  antiquated  in  a  comparatively  few  years.  O.i  the  other 
hand,  there  is  so  much  being  published  in  regard  to  methods  which 
at  first  seem  plausible,  but  which  in  a  few  years  may  be  found  to  be 
wholly  erroneous  or  impracticable.  It  is  therefore  necessary,  in  order 
for  books  to  be  safe,  that  revisions  be  not  too  frequent.  On  the  other 
hand,  if  they  are  to  be  up-to-date  revisions  they  must  not  be  delayed 
too  long.  The  experience  of  the  past  10  years  indicates  that  in  not  only 
the  conception  of  this  handbook,  but  in  its  revisions,  the  author  has 
been  singularly  fortunate,  and  the  third  edition,  which  has  been 
thoroughly  revised  and  brought  up  to  date,  is  to  be  recommended.
