reddening.  The  cause  of  this  coloration  of  carbolic  acid  has  recently  been 
investigated  by  Fabini  (Phar.  Post,  1891,  xxiv,  185);  for  the  production  of  this 
effect  he  found  the  presence  of  ammonia,  hydrogen  binoxide  and  traces  of 
metal  necessary.  A  carbolic  acid,  containing  ammonia  and  a  metal,  rapidly 
turns  red  in  the  presence  of  hydrogen  binoxide  on  warming  ;  but  a  carbolic 
acid,  free  from  metal,  is  never  reddened  on  the  addition  of  ammonia  and 
hydrogen  binoxide.  The  coloring  matter  named  phenerythene,  C30H30NO4, 
is  stated  by  Fabini  to  be  a  derivative  of  quinonimide,  the  sulphate  of  which 
is  indigo  blue." 
To  expedite  the  publication  of  the  year-book  the  labor  has  been  divided, 
each  reporter  presenting  that  class  of  investigations  in  which  he  is  specially 
interested  ;  thus  the  "Year-book  ';  is  naturally  divided  into  a  number  of  chap- 
ters or  sections,  as  follows  :  Chemical  physics,  inorganic  chemistry,  organic 
chemistry,  physiological  chemistry,  pharmaceutical  chemistry,  chemistry  of 
articles  of  food,  agricultural  chemistry,  metallurgy,  inorganic  industrial 
chemistry,  explosives,  technology  of  the  carboh}'drates  and  of  fermentation, 
technology  of  the  fats,  chemistry  of  tar  and  coloring  matters,  photography. 
The  division  of  the  labor  thus  carried  out,  insures  on  the  one  hand  compre- 
hensiveness of  each  report,  and  on  the  other  hand  the  early  publication  of  the 
work  after  the  close  of  each  year,  considerations  which  are  of  weighty 
importance  to  those  who  desire  to  consult  such  reports.  That  each  of  these  is 
as  complete  as  it  can  possibly  be  made  in  the  sense  indicated  above,  may  be 
expected  from  the  collaborators,  and  the  usefulness  of  the  book  is  thus  readily 
seen.  The  external  appearance  of  the  work  is  in  keeping  with  its  internal 
value  and  usefulness.

On  the  appearance  of  the  first  edition  in  1888  we  have  commented  somewhat 
in  detail  on  the  scope  and  character  of  the  work.  The  present  edition  is  in 
the  main  identical  with  the  first  ;  but  some  of  the  vague  statements  contained 
in  the  latter  have  been  corrected  or  modified  in  the  present  edition,  and  a 
fourth  part  on  urinalysis  has  been  added,  covering  over  twenty  pages,  and
