"  These  gentlemen  exhibit  quite  a  list  of  Chemicals,  and  claim  for  them  superior  purity 
considered  as  commercial  articles.  The  Committee  have  carefully  examined  a  number  of 
them  and  find  this  claim  fully  substantiated,  some  of  the  articles  being  almost  absolutely 
Chemically  Pure,  and  being  certainly  the  best  of  the  kind  in  the  market.
