A  Treatise  on  Food  and  Dietetics,  Physiologically  and  Therapeutically  Con- 
sidered. By  F.  W.  Pavy,  M.  D.,  F.  R.  S.  Philadelphia:  Henry  C.  Lea, 
1874.    8vo,  pp.  574. 
No  modern  treatise  on  this  subject  having  existed  in  the  English  language, 
Dr.  Pavy's  work  supplies  a  want  which  has  been  very  seriously  felt,  and  in  a 
manner  which  shows  that  the  author  is  an  extensive  reader  and  has  judiciously 
arranged  the  numerous  facts  and  theories,  together  with  the  most  striking  ex- 
periments and  the  deductions  drawn  therefrom. 
The  introductory  portion  treats  of  the  dynamic  relations  of  food,  its  origina- 
tion and  its  constituent  elements.  The  following  chapter  is  devoted  to  the 
classification,  chemical  relations,  digestion,  assimilation  and  physiological  uses 
of  food,  which  term  is  used  as  "  comprising  that  which  contributes  to  the 
growth  and  nutrition  of  the  body,  and,  by  oxidation,  to  force-production  f  the 
separation  of  the  ingesta  into  41  food  "  and  "  drink  "  is  therefore  not  recognized. 
The  author  is  also  opposed  to  Liebig's  classification  of  food  into  "plastic 
elements  of  nutrition"  and  ''elements  of  respiration,"  and  shows  how  the 
former  may  be  appropriated  to  heat  production— and  some,  at  least,  of  the  latter 
class  to  the  formation  of  tissue.  Food  is  divided  into  two — the  organic  and  in- 
organic divisions — and  the  former  again  into  nitrogenous  and  non-nitrogenous 
principles,  the  latter  forming  two  groups — the  fats  and  carbohydrates — which 
with  the  nitrogenous  principles  and  inorganic  materials,  constitute  four  groups, 
into  which  all  alimentary  principles  are  arranged.  The  general  relations  and 
uses  of  each  group  are  fully  considered  ;  of  particular  interest  appear  to  us  the 
relation  of  nitrogenous  food  and  of  fat  to  the  production  of  muscular  force  and 
of  heat,  the  metamorphosis  and  utilization  of  food  of  the  various  groups,  the 
dietetic  value  of  alcohol,  &c,  the  different  views  and  disputed  theories  being  in 
all  cases  judiciously  arranged  and  lucidly  explained. 
The  following  chapters  are  devoted  to  the  consideration  of  all  alimentary  sub- 
stances in  common  use,  to  the  preservation  of  food,  the  principles  of  dietetics, 
practical  dietetics  and  therapeutic  dietetics. 
It  will  be  seen  from  the  foregoing  that  the  work  may  be  "  instructive  and 
useful"  to  the  educated,  but  more  particular  to  the  medical  practitioner;  and 
when  the  author,  in  the  preface,  expresses  the  hope  th^t  his  task  "  may  not  be 
deemed  superfluous,"  it  seems  to  us  that  he  has  truly  conferred  a  great  benefit 
upon  all  interested  in  the  subject  matter  of  his  work,  and  that  nobody  will  study 
its  pages  without  having  derived  valuable  instruction  therefrom,  and  without 
considering  it  not  only  useful,  but  next  to  indispensable. 
Medical  Literature  of  Kentucky.    By  Lunsford  P.  Landell,  M.D.    Louisville  : 
John  P.  Morton  &  Co.,  Printers.    1874.    8vo,  pp.  52. 
This  interesting  essay,  which  was  read  before  the  Kentucky  State  Medical 
Society,  gives  biographical  sketches  and  reviews  of  the  writings  of  the  medical 
practitioners  of  Kentucky,  commencing  just  previous  to  the  beginning  of  the 
present  century,  and  arranging  the  authors  in  the  order  of  their  appearance. 
An  account  of  the  origin  of  the  medical  schools  of  Kentucky  is  likewise  given.
