which  may  be  represented  at  the  St.  Petersburg  Congress,  and  all  pharmacists,

This  letter  of  invitation  was  laid  before  the  Congress  at  St.  Peters- 
burg, as  stated  further  on.  As  no  response  had  been  received  from 
the  presiding  officers  of  the  Congress  until  nearly  one  year  after 
the  letter  had  been  sent,  the  Permanent  Secretary  of  the  American 
Pharmaceutical  Association  addressed,  on  June  3,  1875,  tne  follow- 
ing inquiry  to  the  President  of  that  Congress : 
The  American  Pharmaceutical  Association  will  hold  its  twenty-third 
annual  meeting  in  Boston  early  in  September,  1875,  and  will  then  determine 
upon  the  proper  measures  for  its  twenty-fourth  meeting,  which  will  convene  in 
Philadelphia  during  the  International  Exhibition  in  1876.  You  are  aware  that 
the  fourth  International  Pharmaceutical  Congress  was  invited  to  call  the  meet- 
ing of  the  fifth  Congress  to  assemble  in  Philadelphia  in  1876.  The  selection 
of  the  proper  place  and  time  having  been  referred  to  the  International  Congress 
Committee,  I  take  the  liberty  of  inquiring  of  you  whether  that  committee  has 
decided  upon  the  invitation  above  referred  to. 
I  also  beg  to  ask  for  information  in  relation  to  the  proposed  draft  of  an 
international  pharmacopoeia  ;  if  possible,  the  American  Pharmaceutical  Asso- 
ciation desires  to  participate  in  its  elaboration.

It  seems  that  no  reply  has  been  received  to  this  letter  neither. 
This  ended  the  first  effort  of  inducing  the  Congress  to  hold  a  meet- 
ing in  the  United  States  during  the  Centennial  year  1876. 
(  To  be  continued.) 
The  Lowering  of  the  Temperature  of  Water  of  maximum  density 
by  solutions  of  various  salts  is  shown  by  de  Coppet  (Compt.  rend.,  May  20, 
1 901)  to  be  proportional  to  the  quantity  of  the  substance  dissolved  and  that  with 
the  exception  of  lithium  salts  the  molecular  lowering  is  almost  constant.
