Proceedings  of  the  American  Pharmaceutical  Association  at 
the  Forty-ninth  Annual  Meeting,  held  at  St.  Louis,  Mo.,  September,

While  an  abstract  of  the  proceedings  of  the  last  meeting  of  this 
Association  has  been  published  in  many  of  the  pharmaceutical  and 
drug  journals,  this  should  only  cause  greater  interest  in  the  official 
records  of  the  Association,  containing  as  they  do  not  only  the 
papers  in  full,  but  the  discussions  which  were  in  some  cases  most 
profitable  and  interesting.  The  progressive  worker  only  requires  a 
hint  to  enlarge  the  sphere  of  his  activity  and  make  more  effective 
the  work  he  is  doing.  In  the  500  pages  of  the  Proceedings  are 
many  hints  for  not  only  the  teacher  and  manufacturer,  but  the  retail 
pharmacist  as  well.  Probably  no  previous  issue  of  the  Proceedings 
has  contained  so  much  in  the  line  of  modern  drug-store  methods, 
particularly  applicable  to  the  work  of  the  retail  pharmacist,  as  the 
volume  now  referred  to. 
The  "  Report  on  the  Progress  of  Pharmacy,"  by  Professor  Diehl, 
serves  to  enhance  the  value  of  the  volume,  and  one  may  well  ask : 
Where  is  there  such  a  repository  of  information  of  the  year's  prog- 
ress as  in  the  Proceedings  of  the  American  Pharmaceutical  Associa- 
tion ? 
The  Elements  of  Physical  Chemistry.  By  J.  Livingston  R. 
Morgan.  Second  edition,  revised  and  enlarged.  X  -(-  352  pp.,  i2mo,

Applied  as  well  as  pure  chemistry  is  dependent  for  its  returns 
upon  the  principles  of  physical  chemistry.  The  labors  of  Ostwald, 
Le  Blanc,  Nernst  and  others  have  caused  almost  a  revolutionary 
aspect  in  regard  to  the  nature  of  solutions,  chemical  reactions 
and  the  role  of  ions  in  analytical  chemistry.  These  subjects  being 
comparatively  new,  many  persons  are  unable  to  obtain  a  compre- 
hensive outline  of  the  subject,  owing  to  the  length  of  time  which  is 
necessary  to  spend  upon  the  separate  volumes  devoted  to  these 
subjects.  This  volume  is  especially  intended  as  a  text-book 
for  either  class-work  or  self-instruction,  and  although  calculus 
is  used  in  the  derivation  of  some  of  the  laws,  still  much  can
