in  Great  Britain  and  the  United  States  that  we  have  this  excellent 
translation  by  Professor  Kremers.  This  work  has  come  naturally 
to  be  looked  upon  as  a  standard  and  is  relied  upon  in  practical  work. 
Students  of  plant -chemistry,  as  well  as  of  the  volatile  oils,  owe  a 
very  great  debt  to  Messrs.  Schimmel  &  Co.  for  publishing  in  such 
excellent  and  permanent  form  the  results  of  the  investigations  in 
their  own  laboratories.  They  might  like  many  other  manufacturers 
have  kept  much  of  this  information  for  their  own  benefit.  It  would 
have  spared  them  not  only  a  very  great  expense,  but  a  great  amount 
of  worry  and  anxiety.  They  preferred,  however,  to  give  to  science 
the  results  of  their  labors.  In  the  giving  of  this  they  have  not  only 
enriched  science  and  chemical  industry  but  they  done  an  ennobling 
work  which  will  stand  as  a. monument  to  this  firm.  It  is  an  example 
that  well  might  be  emulated  by  all  of  the  large  manufacturing  houses.

By  Dr.  Eltore  Molinari.  Translated  from  the  second  enlarged  and 
revised  Italian  edition  by  Thomas  H.  Pope.  With  506  illustrations.

While  it  is  true  that  there  are  several  excellent  English  and  Ameri- 
can works  on  "  Industrial  Organic  Chemistry,"  Molinari's  "  Trattata 
di  Chimica  Organica  "  has  been  highly  esteemed  by  very  many 
European  workers.  It  was  Liebig  who  expressed  the  thought  that 
"  to  obtain  a  sound  practical  man  it  is  necessary  to  train  a  good 
theorist."  Molinari  amplifies  this  maxim  to  meet  modern  needs  by 
saying :  "  In  order  to  produce,  rapidly  and  with  increased  certainty, 
a  sound,  practical  man,  it  is  necessary  to  train  a  good  theorist  and 
to  initiate  him  into  both  the  theoretical  and  practical  study  of  the 
more  salient  industrial  problems."  This  is  the  keynote  of  the  present 
work.  With  a  knowledge  of  various  syntheses  and  constitutional 
formulae  of  a  commercial  product,  he  claims  that  the  chemist  should 
also  possess  a  knowledge  of  industrial  processes  as  well  as  the  statis- 
tics of  production.  In  this  work  we  find  a  lot  of  fundamental  infor- 
mation of  a  general  scientific  character  concerning  organic  compounds 
and  this  is  frequently  supplemented  by  industrial  processes  of  the 
more  important  substances  considered.  The  author  dwells  preferably 
on  the  industries  of  illuminating  gas,  sugar,  alcohol,  beer,  acetic  acid, 
dyeing,  textile  fibres,  fats  and  soaps,  explosives,  etc.
