NOTICE  OF  POSTPONEMENT. 
Iq  consequence  of  the  disturbed  condition  of  the  country,  correspond- 
ence and  consultations  have  been  had  VFith  members  in  various  sections, 
and  it  is  deemed  advisable  to  postpone  the  meeting  of  the  Association, 
which  was  to  have  been  held  at  St.  Louis  in  August  of  this  year,  until 
1862. 
Pursuant  to  the  1st  Section  of  Article  5  of  the  Constitution,  due  notice 
will  be  given  of  the  time  and  place  for  its  next  meeting. 
It  is  earnestly  recommended  to  all  to  keep  in  view  the  important  inte- 
rests of  the  Association — to  the  Committees  to  attend  to  their  several  duties, 
and  especially  to  those  members  and  others  appointed  at  the  meeting  in 
New  York,  to  whom  was  referred  the  investigation  of  special  subjects,  to 
be  ready  to  report  at  the  next  meeting  of  the  Association. 
The  objects  of  the  Association  and  the  conditions  of  membership  are  ex- 
plained in  the  First  and  Second  Articles  of  the  Constitution,  as  published 
in  the  Proceedings  of  last  year,  and  in  the  several  Pharmaceutical  Journals.

On  the  Artificial  Production  of  Alizarin. — M.  Z.  Roussin  has  announced 
to  the  French  Academy,  that  he  has  succeeded  in  producing  the  beautiful 
natural  coloring  principle  of  Madder  by  artificial  means,  by  acting  on 
binitro-naphthalin  by  means  of  concentrated  sulphuric  acid  and  zinc.  The 
author  had  not  completed  his  analysis  of  the  natural  product  in  a  pure 
state,  but  he  has  every  reason  to  believe  it  will  correspond  with  the  arti- 
ficial substance.  The  influence  of  this  discovery  on  the  art  of  dying,  must 
be  marked,  as  the  binitro-naptbalin  being  a  coal  tar  product  can  be  pro- 
duced to  any  extent.  In  our  next  we  will  introduce  the  details  of  the 
process. —  Comptes  Rendus.

Times,  of  May  22d,  gives  the  following  results  as  obtained  by  him  from  a 
chemical  examination  of  various  kinds  of  foreign  paper. 
In  several  samples  of  British  paper  a  notable  quantity  of  sulphate  of 
lime  was  found.
