some  advantages,  since  it  renders  this  part  more  readable,  and  does  away  with 
what  would  tend  towards  a  tabular  presentation  of  the  subject.  A  few  lines  of 
references  are  finally  added,  and  enough  is  before  one  concerning  a  drug  to 
enable  him  to  have  an  intelligent  idea  about  it,  or  to  prosecute  his  studies 
further  elsewhere. 
An  appendix  of  some  30  pages  follows  the  special  part,  and  includes  some  of 
the  very  newest  drugs.  This  is  followed  by  a  literary  index  of  books  and 
journals  used  in  the  references.  The  author  was  somewhat  in  doubt  about 
arranging  the  subjects  in  alphabetical  order,  but  he  had  found  it  best  for  his 
own  use,  so  he  allowed  it  to  stand  ;  but  in  order  to  make  the  work  more  com- 
plete he  added  an  index  of  the  plants,  arranged  according  to  the  natural 
system.    Finally,  there  is  a  very  complete  general  index. 
There  is  no  doubt  but  this  work  will  facilitate  the  study  of  plant  drugs,  and 
aid  in  bringing  some  of  them  more  prominently  before  the  two  professions  of 
pharmacy  and  medicine. 
On  the  Presence  of  a  True  Manna  on  a  "  Blue  Grass,"  Andropogon 
annulatus.  By  R.  T.  Baker,  F.L.S.,  and  Henry  G.  Smith,  F.C.S.  Reprint 
of  paper  read  before  the  Royal  Society  of  New  South  Wales,  December  2, 
1896. 
In  addition  to  identifying  this  substance  as  a  true  manna,  the  authors  have 
made  quite  a  study  of  it  from  botanical,  chemical  and  economic  standpoints. 
The  paper  is  illustrated  by  two  full-page  plates,  and  a  bibliography  of  the  litera- 
ture of  eucalyptus  manna  and  lerp  has  been  appended. 
Report  of  the  Committee  Appointed  by  the  National  Academy  of 
Sciences  upon  the  Inauguration  of  a  Forest  Policy  for  the  Forested 
Lands  of  the  United  States,  to  the  Secretary  of  the  Interior. 
Washington.    Government  Printing  Office,  1897. 
This  report  is  the  result  of  the  appointment  of  a  committee  by  the  president 
of  the  National  Academy  of  Sciences,  on  the  request  of  the  Secretary  of  the 
Interior.  The  report  is  an  exhaustive  one,  and  after  discussing  the  whole  sub- 
ject of  forestry  in  the  United  States,  the  results  are  condensed  into  conclusions 
and  recommendations  that  are  easily  comprehended.  A  number  of  bills  are 
offered  for  presentation  to  Congress  to  enable  the  recommendations  to  be  car- 
ried out.  The  committee  is  composed  of  the  following  well-known  experts  : 
Charles  S.  Sargent,  Henry  L,.  Abbott,  A.  Agassiz,  Wm.  H.  Brewer,  Arnold 
Hague,  Gifford  Pinchot,  Wolcott  Gibbs. 
Ueber  Isomere  MenThylamine  und  Menthene.  By  D.  T.  Werner. 
Inaugural  Dissertation.    Gottingen,  1897. 
This  is  the  result  of  a  careful  study  of  the  properties  of  dextro-  and  laevo-ro- 
tary  menthylamine. 
The  National  Confectioners'  Association  of  the  United  States. 
1897.  This  Association  has  done  a  good  work  in  compiling,  in  a  neat  volume 
of  186  pages,  all  the  "  pure  food  and  pure  candy  laws  "  in  force  in  the  United 
States,  April  1,  1897.  There  is  great  lack  of  uniformity  among  the  different 
States  ;  many  have  no  food  or  candy  laws,  others  have  both,  and  a  number 
hold  that  candy  is  a  food,  and  therefore  apply  the  provisions  of  the  pure  food 
law  to  it.
