process,  by  combining  the  process  of  dissolving  the  sugar  with  that  of 
exhausting  the  powdered  drugs.  For  the  syrup  named  he  proposes 
the  following  manipulation  :  Reduce  to  a  number  20  powder  the  fol- 
lowing drugs:  sarsaparilla,  12 J  ounces,  avoirdupois;  guaiacum,  IJ 
ounces;  pale  rose,  1  ounce;  glycyrrhiza,  1  ounce;  senna,  1  ounce; 
sassafras,  ^  ounce  ;  anise,  J  ounce,  and  gaultheria,  J  ounce.  Moisten 
the  powder  with  a  menstruum  composed  of  1  part  of  alcohol  and  7 
parts  of  water;  when  thoroughly  saturated  transfer  to  a  percolator, 
pack  firmly,  cover  with  a  piece  of  filtering  paper ;  upon  this  ])lace  50 
ounces  of  sugar,  and  gradually  add  more  menstruum  until  the  perco- 
late begins  to  drop ;  then  close  the  lower  orifice,  macerate  for  forty- 
eight  hours,  and  finally  percolate  until  3J  pints  of  syrup  are  obtained. 
Syrupus  Scillce  Compositus  was  made  by  the  same  process  and  with 
equally  good  results,  a  small  quantity  of  ammonia  having  been  added 
to  the  menstruum  with  the  view  of  holding  the  pectiuaceous  principle 
of  senega  in  solution. 
Commercial  Lard. — Norman  G.  Kitter,  Ph.  G.,  prepared  lard  ac- 
cording to  the  Pharmacopoeia  from  the  internal  fat,  the  leaves,  the 
loss  from  the  weight  of  the  crude  fat  being  7.5  per  cent.  Comparing 
it  (No.  1  of  the  table  below)  with  a  number  of  commercial  samples ; 
the  following  results  were  obtained.  The  process  of  analysis  is  not 
given  :

Aside  from  the  water  and  salts  found  in  most,  the  commercial 
specimens  consisted  either  entirely  of  the  external  fat,  or  of  mixtures 
of  the  internal  and  external  fat,  as  indicated  by  their  melting  points. 
The  cost  of  the  lard,  rendered  by  the  author,  was  from  10  to  16  per 
cent,  less  than  that  of  the  samples  examined. 
TJnguentum  Hydrargyri. — Wm.  M.  C.  Craine,  Ph.  G.  examined  a
