Unguentum  Hydrargyri. — Lunaczek  modifies  Godeffroy's  process 
(see  "Amer.  Jour.  Pharm.,"  May,  1879,  p.  247)  as  follows:  1  gram 
turpentine  and  2  grams  liquid  petroleum-residue  thickened  with  a  little 
.paraffin  or  ceresin  are  mixed  and  triturated  well  with  40  grams  mercury 
for  a  few  minutes,  when  5  or  10  grams  old  mercurial  ointment  are  stirred 
into  the  mixture,  and  the  trituration  is  continued  until  the  mercury  is 
completely  extinguished  ;  then  the  suet  and  lard  are  melted  together, 
and  when  they  commence  to  stiffen  are  added  to  the  mercury  mixture.
