an  alcohol  or  gas  flame  to  melt,  then  pour  the  melted  alum  into 
moulds  of  paraffine  paper  previously  prepared.  Combinations  of 
alum  and  copper  sulphate  may  be  prepared  in  the  same  way. 
For  copper  sulphate  points,  the  same  paper  recommends  the  use 
of  a  finely  powdered  salt  triturated  with  enough  mucilage  of  gum 
arabic,  or  with  simple  syrup,  so  as  to  give  the  mass  some  plastic 
properties ;  this  mass  is  then  formed  by  hand  into  the  desired  shape 
and  allowed  to  harden  for  several  days.

REVIEWS  AND  BIBLIOGRAPHICAL  NOTICES. 
Proceedings  of  the  American  Pharmaceutical  Association  at 
the  fiftieth  annual  meeting,  held  at  Philadelphia,  Pa.,  September, 
1902.  Also  the  constitution,  by-laws  and  roll  of  members.  Bal- 
timore, 1902. 
This  volume,  containing,  as  it  does,  the  account  of  the  proceedings 
a.t  the  semi-centennial  celebration  of  the  American  Pharmaceutical 
Association,  has  been  anxiously  awaited  by  nearly  every  member  of 
the  Association.  It  is  probably  the  largest  volume  of  proceedings 
that  has  been  published  by  the  Association,  containing,  as  it  does,  a 
total  of  1,266  pages  of  printed  matter. 
Considering  the  size  of  the  volume,  and  the  variety  as  well  as 
importance  of  the  contained  material,  the  officers  of  the  Association 
having  the  publication  in  charge  are  to  be  congratulated  on  the 
satisfactory  way  in  which  they  have  accomplished  their  task. 
Six  hundred  and  fifty-six  pages  are  devoted  to  the  recording  of 
the  minutes  of  the  proceedings,  including  the  texts  of  the  papers 
that  were  contributed.  This  portion  of  the  work  has  been  reviewed 
quite  extensively  in  this  journal  (see  A.  J.  P.,  1902,  page  461  et  seq.) 
and  will  need  no  further  comment  other  than  to  say  that  the  re- 
corded pages  evidence  an  active  interest  in  matters  pertaining  to 
pharmacy  on  the  part  of  the  members  of  the  Association. 
The  second  portion  of  the  book, "  Report  on  the  Progress  of  Phar- 
macy," takes  up  434  pages  of  the  book  and  constitutes  one  of  the
