MANUFACTURING  CHEMIST  AND  DRUGGIST, 
3tiEW  MARKET,  ABOVE  LAIREL  STREET,  PHILADA. 
Would  respectfully  call  the  attention  of  Druggists  to  the  articles  of 
his  manufacture,  among  which  are, 
MEDICINAL  EXTRACTS, 
PREPARED  IN  VACUO, 
In  all  their  variety,  warranted  of  superior  quality,  made  according  to 
the  best  formula,  (by  the  U.  S.  Pharmacopoeia  when  officinal.)  Strict 
attention  is  paid  to  the  selection  of  prime  Drugs  for  their  manufacture, 
as  well  as  to  all  the  minutiae  in  the  manipulation.  They  are  neatly 
put  up  in  packages  of  any  description  that  may  be  ordered. 
POWDERED  EXTRACTS.— All  the  extracts  that  can  be  powdered 
without  injury,  will  hereafter  be  kept  in  that  way  for  the  convenience 
of  Druggists  and  others;  also,  Concentrated  Medicines  used  in  Eclectic 
practice,  including  Resinoids,  Oleo-  Resinoids,  Alka-Resinoids  j 
also,  Fluid  Extracts  in  all  their  variety. 
All  of  the  above  preparations  will  hereafter  be  prepared  in  vacuo, 
GLYCERIN,  anhydrous,  colorless  and  inodorous;  much  superior  to 
the  common  English  article. 
MACHINE  SPREAD  PLASTERS,  superior  to  any  other  in  the 
market.  These  plasters  are  on  the  finest  lambskin,  prepared  in  such  a 
manner  as  to  retain  their  pliability  and  freshness  of  appearance.  They 
are  neatly  put  up  in  boxes  of  one  dozen  each,  and  are  warranted  to  give 
satisfaction. 
Also,  ADHESIVE  PLASTER  CLOTH,  that  will  compare  favor- 
ably with  any  other. 
PLASTERS  IN  ROLLS,  of  superior  quality,  believed  to  be  equal  to 
the  English  Plasters. 
BLUE  MASS,  warranted  one-third  Mercury,  and  made  in  such  a  way 
as  cannot  fail  to  give  satisfaction. 
MERCURIAL  OINTMENT,  of  all  the  various  proportions  that  are 
in  demand,  made  by  a  Machine  that  divides  the  Mercury  to  the  finest 
possible  state,  without  the  aid  of  any  acid  or  injurious  substance. 
HYDRARG.  CUM  GRETA,  of  superior  quality,  also  all  the  Phar- 
maceutical Preparations,  usually  in  demand,  all  of  which  will  be  sold 
on  terms  which  cannot  fail  to  be  satisfactory. 
SELECT  POWDERS  of  the  finest  quality,  of  every  kind,  including 
Powdered  Blue  Mass,  Powdered  Prepared  Ox  Gall,  and  some  other 
articles  not  heretofore  used  in  that  way.  They  are  neatly  put  up  in 
packages  of  any  size  and  description,  or  in  bulk,  as  may  be  ordered. 
PURE  GROUND  SPICES,  &c,  warranted  to  be  made,  (in  all  in- 
stances,) from  articles  of  prime  quality,  handsomely  put  up  or  in  bulk, 
as  may  be  ordered,  free  from  any  adulteration  whatever. 
The  above-mentioned  articles  are  all  manufactured  at  my  own  works, 
New  Market  St.  abo"e  Laurel,  and  are  guaranteed  to  be  satisfactory.  ^

cals, Glass  Ware,  White  and  Blue  Jars,  Paints,  Dyes,  Colors,  Acids,  and
