less,  every  expert  investigator  should  be  given  credit  for  his 
work,  and  where  differences  of  opinion  hold  the  Pharmacopoeia  should 
be  more  general  in  its  definitions  and  define  the  drugs  to  which  these 
■differences  apply  as  being  obtained  from  "  probably  other  species  " 
and  as  "  consisting  chiefly  of"  certain  plant  parts.  Furthermore,  in 
the  description  of  properties  and  tests  the  limit  of  impurity  or  admix- 
ture could  be  defined  ;  or,  in  other  words,  definitions  and  descrip- 
tions, as  well  as  tests,  should  be  based  upon  the  article  in  the  market.

A  Handbook  of  Industrial  Organic  Chemistry  adapted  for 
the  use  of  manufacturers,  chemists  and  all  interested  in  the  utiliza- 
tion of  organic  materials  in  the  industrial  arts.  By  Samuel  P. 
Sadtler.  Third  revised  and  enlarged  edition.  Philadelphia :  J.  B. 
Lippincott  Company. 
The  first  edition  of  this  work  was  published  in  1891  and  the  sec- 
ond in  1895.  At  the  time  of  the  publishing  of  the  first  edition  there 
was  no  concise  work  in  the  English  language  treating  of  applied 
organic  chemistry,  and  the  book  was  a  welcome  addition  to  works 
on  chemical  technology.  Since  that  time  the  value  of  the  work  has 
been  shown  by  the  necessity  for  two  revisions  and  the  translation  of 
the  book  into  German. 
The  contents  of  the  book  consist  of  a  concise  treatment  of  fourteen 
different  classes  of  industries,  including  the  following  particulars  of 
each  :  (a)  Raw  Materials ;  (b)  Processes  of  Treatment ;  (c)  Products  ; 
(d)  Analytical  Tests  and  Methods ;  (e)  Bibliography  and  Statistics. 
The  classes  of  industries  treated  of  are  the  following  :  (1)  Petroleum 
and  Mineral  Oil  Industry ;  (2)  Industry  of  the  Fats  and  Fatty  Oils ; 
{3)  Industry  of  the  Essential  Oils  and  resins;  (4)  The  Cane  Sugar 
Industry  ;  (5)  The  Industries  of  Starch  and  its  Alteration  Products  ; 
(6)  Fermentation  Industries,  including :  (a)  Nature  and  Varieties  of 
Fermentation  ;  (6)  Malt  Liquors  and  the  Industries  Connected  There- 
with ;  (c)  The  Manufacture  of  Wine ;  (d)  Manufacture  of  Distilled 
Liquors  or  Ardent  Spirits;  (e)  Bread-Making ;  (/)  The  Manufac- 
ture of  Vinegar ;  (7)  Milk  Industries ;  (8)  Vegetable  Textile  Fi- 
bres, including :  (a)  Paper-making;  (J?)  Guncotton,  Pyroxyline, 
Collodion  and  Celluloid  ;  (9)  Textile  Fibres  of  Animal  Origin  ;  (10)
