sections  in  Lewkowitsch's  "  Chemical  Analysis  of  Oils,  Fats  and 
Waxes  "  be  referred  to  this  will  be  easily  shown.  The  new  edition 
of  Allen's  "  Commercial  Organic  Analysis "  also  is  much  more 
satisfactory  in  this  respect. 
The  book,  however,  contains  a  vast  amount  of  useful  information, 
compactly  presented  and  conveniently  arranged  in  tabular  form. 
It  will  no  doubt  fill  the  author's  claim  that  it  will  be  a  very  useful, 
handy  book  for  reference  in  examining  the  fixed  oils  and  fats.

The  Volatile  Oils.  By  E.  Gildemeister  and  Fr.  Hoffmann. 
Written  under  the  auspices  of  the  firm  of  Schimmel  &  Co.,  Leipzig. 
Authorized  translation  by  Edward  Kremers.  With  four  maps  and 
numerous  illustrations.  Milwaukee:  Pharmaceutical  Review  Pub- 
lishing Company.    1900.    $5  net. 
The  American  edition  contains  all  the  valuable  features  of  the 
original  German  edition,  which  was  reviewed  in  this  Journal,  1899, 
p.  439,  and,  in  addition,  the  translator  has  brought  the  book  up  to 
date.  Dr.  Kremers'  continued  work  on  the  volatile  oils  has  ren- 
dered him  particularly  competent  to  undertake  the  translation. 
The  contents  of  the  work  are  distributed  as  follows : 
I.  Historical  Introduction :  The  spice  trade  in  antiquity  and 
during  the  Middle  Ages  ;  history  of  volatile  oils ;  history  of  the 
methods  of  distillation  and  of  distilling  apparatus. 
II.  General  Part :  The  theoretical  basis  for  obtaining  volatile  oils 
by  steam  distillation  ;  the  more  commonly  occurring  constituents  of 
volatile  oils ;  the  examination  of  volatile  oils ;  list  of  plants,  ar- 
ranged according  to  families,  from  which  volatile  oils  are  obtained. 
Special  Part':  History,  origin,  preparation,  properties,  composition, 
examination  and  commercial  statistics  of  the  volatile  oils.  The 
Bibliographical  Notes  have  been  placed  in  an  appendix.  A  com- 
prehensive Index  cotnpletes  the  volume. 
The  volatile  oils  represent  a  group  of  plant  constituents  of  pecu- 
liar interest  to  the  apothecary  as  well  as  pharmaceutical  or  manu- 
facturing chemist,  and  it  is  extremely  fortunate  that  there  is  a  com- 
prehensive authentic  work  in  English  bearing  on  this  subject.
