chemical  research,  pathological  chemistry,  pharmacy,  metallurgy, 
manufacturing  chemistry,  photography,  etc.,  and  for  the  valuation 
of  substances  used  in  commerce,  agriculture  and  the  arts.  By 
Francis  Sutton.  Ninth  edition,  revised  and  enlarged.  Philadel- 
phia: P.  Blakiston's  Son  &  Co.,  1904. 
This  work  by  Sutton  is  so  well  known  that  it  hardly  requires 
more  than  a  mention.  Dr.  Knecht's  process  for  the  estimation  ol 
azo  dyes,  nitro-  and  nitroso-compounds  by  the  use  of  titanous  chlo- 
ride is  given  on  pages  366-369.  A  condensed  record  of  analyses  of 
various  compounds  existing  in  gas  liquor  and  the  methods  of  deter- 
mining them  as  carried  out  by  the  Chief  Inspector  under  the  Alkali 
Works  Regulation  Acts  has  been  included  in  this  new  edition  (p.  77, 
etc.).  Sodeau's  gas  apparatus,  a  modification  of  Macfarlane  and 
Caldwell's  apparatus,  and  adapted  for  gas  analysis  of  the  highest  ac- 
curacy is  described  on  pages  569-572.  Throughout  the  book  are 
numerous  references  to  recent  literature  indicating  that  the  book 
has  been  brought  up  to  date,  and  thus  it  continues  to  be  one  of  the 
most  valuable  all-around  laboratory  manuals  on  industrial  chemistry 
in  its  many  phases. 
The  Art  of  Compounding.  A  text-book  for  students  and  a  ref- 
erence book  for  pharmacists  at  the  prescription  counter.  By  Wilbur 
L.  Scoville.  Third  edition,  revised  and  enlarged.  Philadelphia ; 
P.  Blakiston's  Son  &  Co.,  1904.    $2.50,  net. 
One  of  the  most  hopeful  signs  in  American  pharmacy  is  the  dis- 
position of  authors  to  write  books  which  contain  not  only  a  new 
presentation  of  the  subject  but  something  also  in  the  application,  at 
least,  that  is  new.  Scoville's  book  has  now  gone  through  several 
editions,  each  of  which  has  been  wide  awake  to  the  present  tenden- 
cies and  needs  of  the  pharmacist.  One  of  the  most  happy  introduc- 
tions is  the  chapter  on  "  Sterilization,"  etc.  This  is  well  written 
and  is  deserving  of  careful  attention  by  the  pharmacist.  When  the 
brewer,  the  bottler  and  even  the  farmer  are  practically  carrying  on 
work  involving  modern  researches  in  bacteriology,  surely  the  phar- 
macist should  know  how  to  preserve  his  drugs  and  preparations 
and  dispense  prescriptions  that  are  free  from  harmful  micro, 
organisms. 
The  chapter  on  tablets  and  the  manufacture  of  compressed  and 
triturate  tablets  will  also  be  found  valuable,  as  many  pharmacists
