191 1.  In  this  edition  there  were  354  pages  of  subject  matter  and 
10 V2  pages  of  index.  The  present  edition  (February,  1919)  con- 
tains 784  pages  of  body  matter,  37  pages  of  author  index  and  21 
pages  of  subject  index.  Most  of  the  body  of  the  book  is  devoted 
to  tabular  arrangements  of  solubiHty  data,  but  there  are  18  pages 
of  general  information  explaining  the  use  of  the  tables  and  giving 
reasons  for  the  appearance  of  some  of  the  data  in  the  book ;  and  there 
are  28  pages  on  methods  for  determining  solubiHties,  with  illustra- 
tions of  the  most  important  of  the  apparatus  described  in  the  text. 
The  names  of  the  substances  for  which  solubilities  are  given  are 
arranged  alphabetically,  the  pages  and  paragraphs  being  headed  in 
bold-faced  type  for  easy  reference.  The  authority  for  the  data  in 
each  instance  is  given  by  name  of  author  and  year  data  was  published, 
while  in  the  back  of  the  book  are  to  be  found  two  pages  giving  the 
names  of  the  50  periodicals  from  which  the  data  were  collected, 
paged  so  that  the  original  article  can  be  traced  easily. 
In  preparing  a  review  of  a  book  of  this  character  it  is  difficult 
to  find  a  place  of  attack,  as  the  reading  of  784  pages,  chiefly  of  tab- 
ular matter  in  rather  fine  print,  is  apt  to  be  exceedingly  tiresome 
without  "getting  one  anywhere."  Something  of  the  scope  of  the 
book  may  perhaps  be  gathered  from  the  examination  of  the  data 
given  for  a  few  substances.  Taking  seven  somewhat  at  random, 
we  find  that: 
For  Quinine  (p.  576)  the  solubility  is  given  in  19  different  liquids, 
in  some  at  3  different  temperatures. 
For  Radium  Emanations  (p.  580)  the  solubility  is  given  in  15 
liquids,  at  0°  C.  and  at  18°  C. 
For  Carbon  Dioxide  (p.  ^^4)  the  solubility  is  given  in  44  different 
liquids,  at  3  different  temperatures. 
Five  pages  are  devoted  to  solubilities  of  Phenol,  eight  to  Ethyl 
Alcohol,  ten  to  Mercuric  Chloride,  nine  to  Iodine,  each  in  a  great 
variety  of  liquids  and  under  a  great  variety  of  conditions.  In  the 
case  of  Iodine  (for  illustration)  the  solvents  named  include  water, 
alcohol,  benzene,  chloroform,  ether,  bromoform,  carbon  disulphide, 
•carbon  tetrachloride,  aqueous  solutions  of  potassium  iodide,  mer- 
curic chloride,  potassium  bromide,  sodium  chloride,  hydrochloric  acid 
and  a  number  of  other  salts  and  acids,  together  with  a  lot  of  mixed 
solvents,  each  substance  being  used  in  various  strength  solutions. 
One  who  examines  the  subject  matter  of  the  book,  even  very 
superficially,  cannot  help  being  amazed  at  the  vast  amount  of  work
