Styracol  (the  cinnamic  acid  ester  of  guaiacol)  is  recommended  on 
account  of  its  being  a  comparatively  non-toxic  preparation  of 
guaiacol.  It  is  odorless  and  tasteless,  and,  in  addition  to  its  possible 
use  in  the  treatment  of  tuberculosis,  has  been  used  in  intestinal  colic 
and  summer  diarrhoea.  The  dose  is  given  as  being  roo  three  or 
four  times  a  day.    {Slid.  Deut.  Apoth.  Zeit.,  1904,  page  626.)

A  Compendium  of  Chemistry,  including  General,  Inorganic 
and  Organic  Chemistry.  By  Dr.  Carl  Arnold,  authorized  trans- 
lation from  the  eleventh  German  edition  by  John  A.  Mandel,  Sc.D., 
Professor  of  Chemistry  in  the  University  and  Bellevue  Hospital 
Medical  College.  New  York  :  John  Wiley  &  Sons.  1904.  Small 
8vo,  627  pages.  $3.25. 
This  is  the  first  American  edition  of  the  well-known  "  Repetito- 
rium  der  Chemie  "  of  Arnold,  which  has  gone  through  numerous 
editions  in  Germany.  The  translator  says  :  "  The  eleventh  and  last 
edition  contains  concise  but  clear  statements  of  the  most  important 
theories  and  facts,  especially  in  the  recently  developed  domain 
of  physical  chemistry,  as  well  as  a  classified  review  of  the  most 
important  inorganic  and  organic  compounds,  including  statements 
of  the  constitution  and  derivation  of  these  substances." 
In  the  division  of  the  subject  as  given  in  the  title,  we  find 
95  pages  taken  up  with  general  chemistry,  200  with  inorganic  chem- 
istry, both  non-metallic  and  metallic,  and  277  with  organic  chem- 
istry. While  this  relatively  large  proportion  of  space  given  to 
general  or  theoretical  chemistry  makes  the  book  very  satisfactory  to 
an  advanced  chemical  student  for  review  or  for  the  practising  chem- 
ist as  a  compend  to  turn  to,  it  prevents  its  use  with  the  beginner, 
as  the  theory  is  all  massed  together  at  the  outset  before  the  descrip- 
tive part,  some  acquaintance  with  the  experimental-  side  of  chemis- 
try being  needed  for  the  proper  understanding  of  this  mass  of 
theory.  However,  the  theory  is  very  well  stated.  After  discussing 
under  the  heading  "  Stoichiometry,"  the  subject  of  atoms,  mole- 
cules, symbols,  formulas,  valence,  and  properties  of  elements,  the 
author  proceeds  to  take  up,  under  the  heading  "  Chemical  Affinity," 
the  subject  of  chemical  mechanics  (chemical  dynamics  and  chemical 
statics),  thermo-chemistry,  electro-chemistry  and  photo-chemistry.
