We  presume  a  commission  has  been  or  will  soon  be  appointed  by  our 
national  government,  as  the  period  for  receiving  the  goods  at  Paris  is 
rapidly  approaching.  The  excellent  tendency  of  these  international  exposi- 
tions in  the  encouragement  of  commerce  and  the  peaceful  arts,  and  in  the 
promotion  of  good  feeling  among  distant  nations,  should  induce  a  strong 
effort  to  render  them  as  universal  as  possible.  Our  great  distance  from  the 
point  of  exhibition,  and  the  scattered  state  of  our  population,  not  to 
speak  of  the  youthful  condition  of  many  of  the  arts  and  manufactures  here, 
present  obstacles  to  contributors  not  felt  in  European  countries,  and  will 
probably  render  the  contributions  from  the  United  States  less  interesting  as 
objects  of  art  than  for  utility. 
Cantharides  among  the  Lawyers,  or  what  is  the  normal  per  centage  of 
hygroscopic  water  in  Spanish  flies? — It  was  our  unwilling  lot  to  witness  the 
proceedings  in  a  recent  case  tried  in  the  District  Court  in  reference  to  a  lot 
of  cantharides,  and  a  sketch  of  the  facts  may  not  be  without  use  to  some  of 
our  readers.    A  ,  a  powderer,  being  in  want  of  cantharides,  bought  a 
lot  of  100  lbs.  from  B  ,  a  druggist,  at  $2.70  per  lb.,  without  examining 
them.    When  A  received  the  flies  he  found  them  too  damp  to  powder, 
and  gave  directions  to  have  them  dried  on  a  steam  heated  surface  at  100°
