"General  and  Industrial  Chemistry,  Organic."  Part  I,  Second 
Edition.    By  Dr.  EttorE  Molinarl,  translated  from  the  Third 
;  Italian  Edition  by  Thos.  H.  Pope,  B.  Sc.  $8.00  net.  P.  Blaki- 
ston's  Son  &  Co.,  Philadelphia,  Pa. 
This  work,  containing  254  illustrations,  covers  in  441  pages 
what  appeared  in  369  pages  of  the  first  English  Edition,  but  the 
gain  is  more  apparent  than  real,  as  the  type  used  in  the  fine  print 
articles,  of  which  there  are  a  large  number,  is  between  15  and  16 
per  cent,  larger  than  that  used  in  the  previous  edition.  This  accounts 
in  large  measure  for  the  increased  number  of  pages  devoted  to  such 
industries  as  those  of  Illuminating  Gas,  Petroleum,  and  Ethyl 
Alcohol. 
There  is  considerable  new  matter,  however;  for  instance,  a 
half-page  on  Alcohol  from  the  Sulphite  Liquors  from  the  Paper 
Works,  two-thirds  page  on  Alcohol  from  Calcium  Carbide,  a  half- 
page  on  the  Recovery  of  Ether  from  the  Air,  a  half-page  on  Chem- 
istry and  the  War,  and,  here  and  there,  smaller  items  of  new  matter. 
A  number  of  articles  have  been  rewritten,  notable  among  these 
being  those  on  The  Industrial  Preparation  of  Methyl  Alcohol,  and 
Tests  for  Methyl  Alcohol.  Nearly  all,  probably  all,  of  the  matter 
has  been  reset,  much  of  it  without  change  of  language;  with 'the 
result  that  the  book  contains  some  statements  which  were  true  when 
the  first  edition  was  written  but  not  now,  and  others  which  were 
doubtful  as  to  truth  when  first  written  are  perpetuated  in  the  new 
book.  For  example,  on  page  34  (33  in  1st  Ed.)  we  read  "at  Pitts- 
burg there  are  great  wells  of  pure  methane,"  doubtless  referring  to 
the  very  prolific  natural  gas  wells  which,  for  a  number  of  years 
about  the  beginning  of  the  present  century,  made  that  city,  undeserv- 
ing of  its  title  "The  Smoky  City,"  but  which  for  a  dozen  or  more 
years  past  have  been  little  more  than  a  pleasant  memory.  On  page 
ri9  we  read  "theaise  of  chloroform'  has  been  suggested  to  render
