described,  but  their  derivatives  are  considered  together  as  fatty  acids,  fats^ 
and  carbohydrates,  and  these  are  followed  by  uric  acid  and  its  derivatives, 
including  several  animal  and  vegetable  compounds  like  xanthine,  sarcine, 
theobromine,  etc.  This  part  of  the  work  closes  with  a  retrospect  for  the 
consideration  of  the  general  characters  of  the  analogous  compounds  derived 
from  the  different  hydrocarbons,  such  as  aldehyds,  ketones,  esters,  amine 
bases,  etc. 
The  second  part  of  the  work  is  devoted  to  the  aromatic  compounds,  which 
in  a  manner  similar  to  that  sketched  before  are  evolved  from  the  hydro- 
carbons, benzene,  toluene,  xylene,  cumene,  and  cymene,  followed  by  the 
compounds  produced  through  the  reduction  of  benzene  derivatives,  by  the 
indigo  group  and  a  few  condensation  compounds,  and  finally  by  a  retro- 
spect. 
The  remaining  portion  of  the  work  treats  of  naphthalene,  anthracene, 
chrysene  with  allied  hydrocarbons  and  derivatives,  and  a  number  of  natu- 
ral compounds  nearly  all  of  undetermined  constitution,  namely,  camphor, 
essential  oils,  resins,  pyridine  bases;  the  latter  being  considered  in  thi& 
place  owing  to  their  close  relation  to  the  alkaloids  which  follow  next,  then 
the  glucosides,  coloring  matters,  bitter  principles,  biliary  substances  and 
protein  compounds.  An  appendix  gives  instructions  in  the  estimation  of 
the  elements  of  organic  compounds,  the  determination  of  vapor  density 
and  of  the  constitution  of  organic  compounds,  in  condensation,  polymeriz- 
ation, atomic  migration,  etc. 
Et  will  be  observed  from  the  foregoing  that  the  plan  of  the  work  has  been 
well  matured  and  consistently  carried  out.  Being  intended  for  a  text-book, 
and  not  as  a  work  of  reference,  the  details  which  are  expected  to  be  found 
in  the  latter  are  necessarily  absent ;  in  fact  it  represents,  in  a  thoroughly 
systematic  manner,  the  framework  of  the  science  of  chemistry  confined  to 
the  carbon  compounds,  and  as  such  must  be  a  most  valuable  guide  to  the 
student  who  is  anxious  to  obtain  more  than  a  superficial  knowledge  of  this 
branch.  The  translation  has  been  creditably  done,  and  the  proof-sheets 
have  been  well  read,  only  few  typographical  errors  having  been  noticed  by 
us  ;  a  copious  index,  covering  20  pages,  facilitates  the  use  of  the  work.

education  as  a  prerequisite  to  the  study  of  medicine  and  other  sciences.
