Ointment  of  Boroglyceride. — Clarence  E.  Dowries,  Ph.G.,  states  such 
an  ointment  is  made  in  the  Jefferson  Hospital  by  heating  one  part  of 
boroglyceride,  containing  50  per  cent,  of  boric  acid,  and  while  hot, 
adding  it  slowly  to  three  parts  of  petrolatum,  the  stirring  being  con- 
tinued until  the  mixture  has  thoroughly  cooled,  in  order  to  avoid  sep- 
aration of  the  ingredients.  The  ointment  is  a  very  convenient  vehicle 
for  atropine,  physostigmine,  chloride  of  zinc  and  other  remedies. 
Unguentum  Zinci  Oxidi—  Jos.  P.  Williams,  Ph.G.,  recommends  a 
somewhat  firmer  ointment  than  the  officinal.  It  is  made  by  tritura- 
ting 5  oz.  of  oxide  of  zinc  with  4  oz.  of  glycerin  until  a  smooth  paste 
is  obtained.  Then  melt  1  oz.  of  white  wax,  add  gradually  15  oz.  of 
benzoinated  lard,  keeping  the  temperature  near  140°  F.;  now  stir 
until  the  mixture  begins  to  thicken,  add  the  zinc  oxide  prepared  as 
before,  and  continue  the  stirring  until  thoroughly  mixed  and  perfectly 
smooth. 
Troches. — After  experimenting  with  various  excipients  for  troches, 
Ellsworth  S.  Adams,  Ph.G.,  observes  that  currant  paste  deserves  to 
be  more  frequently  used,  and  that  a  jelly  prepared  from  starch  and 
gum  arabic  furnishes  one  of  the  best  general  excipients.  Powdered 
gum  arabic  and  starch,  of  each  1  oz.,  are  well  mixed,  triturated  with 
3  fluidounces  of  water,  and  the  mixture  heated  to  boiling  until  solution 
has  been  effected.
