Tlie  different  classes  of  the  vertebrates  are  rei^resented  by  the  skate,  cod, 
sahimander,  tortoise,  j^igeon  and  rabbit,  the  ilhistrations  showing  the 
external  characters,  internal  organs,  skeleton,  nervous  system,  sense- 
organs,  urino-genital  organs  and  the  organs  of  alimentation,  circulation 
and  respiration. 
The  two  volumes,  it  will  be  observed,  coyer  the  entire  range  of  the 
natural  groups  of  the  animal  kingdom  by  judiciously  selected  species. 
Wherever  it  was  found  desirable,  brief  directions  have  been  given  to  aid  the 
student  in  dissecting,  and  of  a  number  of  the  lower  forms  of  animals  the 
principal  stages  of  development  are  given,  and  the  life  history  is  illustrated 
by  diagram.  As  far  as  we  are  able  to  judge,  the  illustrations  are  correct 
and  clear ;  they  are  undoubtedly  very  instructive,  and  must  prove  to  be  a 
most  valuable  assistance  to  the  student  of  zoology  and  comparative  anat- 
omy. It  is  universally  recognized  that  in  the  study  of  natural  history  a 
thorough  acquaintance  with  the  external  characters  and  with  the  internal 
structure  is  absolutely  necessary.  A  knowledge  of  the  former  is  acquired 
by  attentive  observation  and  judicious  comparison.  But  to  acquire  a 
knowledge  of  the  internal  structure,  the  practical  labor  of  dissecting  and 
isolating  the  different  tissues  and  framework  is  of  far  greater  value  than 
the  mere  examination  of  dissected  specimens  or  of  carefully  executed 
plates  ;  the  object  of  both  these  aids  should  be  to  assist  in  practical  labor, 
and  this  aim  is  well  fulfilled  in  the  work  before  us,  in  the  judicious 
selections,  correct  drawings,  careful  coloring,  explanatory  descriptions, 
and  in  the  attractive  mechanical  execution  of  the  zoological  atlas. 
A  Treatise  on  Food  and  Dietetics  PJiysiologically  and  Therapeutically 
Considered.  Bv  F.  W.  Pavy,  M.D.,  F.R.S.',  etc.  Second  edition.  New 
York  :  Wm.  Wood  &  Co.    1881.    8vo,  pp.  402. 
The  first  edition  of  this  work  was  noticed  by  us  in  1874  (this  journal, 
1874,  13.  400),  and  favorably  commented  upon.  The  second  edition  has 
been  revised  and  modified  so  as  to  render  the  meaning  of  certain  state- 
ments clearer,  and  a  considerable  amount  of  new  matter  has  been  added; 
it  is  now  issued  as  the  tenth  volume  of  Wood's  library  of  standard  medi- 
cal authors.

We  have  noticed  the  a2:>j)earaiice  of  the  first  edition  of  this  work  in 
^'Amer.  Jour.  Phar.,"  1870,  p.  315.  Of  the  second  edition,  which  will  em-
