act  from  Report  of  the  Judges  at  the  Exhibition  of  the  Franklin  Institute,  Philadelphia*, 
November,  1874,  in  regard  to  Chemicals  exhibited  by  Rosengarten  &Sons. 
"  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  this  best  of  the  kind  in  the  market.

The  most  perfect  BASE  as  yet  discovered  for  Ointments,  Pomades,  etc.  This  lard  is  abso- 
lutely pure,  it  contains  no  water  and  no  impure  matter  of  any  nature  whatsoever,  and  will  keep 
in  any  climate  without  becoming  rancid.  It  is  of  a  firm,  solid  consistency,  and  well  adapted  to- 
the  uses  of  the  Druggist  and  Physician,  who  are  invited  to  examine  it. 
The  following  letter  is  from  a  practical  chemist  who  has  tried  it  : 
MR.  F.  K.  ED  WARDS.— Dear  Sir  :  "  Having  occasion  to  prepare  a  considerable  quantity  of 
Ointment,  in  which  a  Salt  of  Lead  is  added  to  the  melted  Lard  at  an  elevated  temperature,  I 
obtained  a  perfectly  smooth  unguent  without  any  chemi<  al  change.  This  satisfied  me  the  Lard 
was  anhydrous,  for,  as  all  chemists  know,  if  water  had  beer  p.esent  even  in  small  quantities,  a 
reaction  between  the  Fatty  Acids  and  the  Lead,  and  consequent  liberation  of  Glycerine  (or  wot 
other  words  saponification),  would  have  been  the  result."  Very  truly, 
(Buffalo,  N.  Y.,  Nov.  8th,  1878.)  R.  K.  SMITHER.
