60  cc.  Warm  the  mixed  oils  on  the  water  bath  to  Jo°  C;  dissolve 
the  potassa  in  the  water  and  warm  this  also  to  700  C.  and  add  this 
to  the  oils  and  stir  thoroughly.  Now  add  the  alcohol,  and  as  soon 
as  this  is  thoroughly  incorporated  stop  stirring.  Continue  the  heat 
at  this  temperature  for  a  short  time  until  saponification  is  complete, 
which  is  evidenced  by  the  mass  becoming  clear  and  a  portion  dissolv- 
ing in  boiling  water  or  alcohol  without  the  separation  of  oil  globules. 
If  the  above  directions  are  followed,  the  resulting  soap  is  an  almost 
transparent,  smooth,  greenish-yellow  mass,  but  if  stirring  is  con- 
tinued after  the  addition  of  the  alcohol  until  the  saponification  is 
completely  effected,  then  the  resulting  soap  is  opaque  from  included 
air.

Practical  Dispensing  Notes. 
By  Lewis  C.  Hopp. 
The  author  gave  some  notes  on  the  filling  of  capsules  and  exhib- 
ited a  suppository  mold  weighing  seven  pounds  which,  he  said, 
furnished  the  advantage  of  thoroughly  chilling  the  suppositories. 
He  also  exhibited  an  apparatus  for  mixing  and  sifting  powders. 
Other  Papers. 
Several  papers  were  read  by  title :  "  Waste  and  How  to  Prevent 
It,"  by  Wm.  Mittelbach ;  "  Pharmaceutical  Fragments,"  by  W.  W. 
Kerr ;  "  Incompatibility  in  a  Prescription  for  Pills,"  by  E.  Fullerton 
Cook. 
Historical  Committee. 
An  entire  evening  (Tuesday)  was  devoted  to  the  work  of  the 
Historical  Committee.  The  chairman,  Edward  Kremers,  presented 
an  elaborate  report  outlining  the  plan  of  work  proposed  by  the 
committee.  He  said  that  the  interest  manifested  at  the  Philadelphia 
meeting,  in  the  history  of  American  pharmacy,  caused  some  of  the 
members  to  consider  the  desirability  of  perpetuating  this  interest. 
It  was  thought  desirable  at  first  to  appoint  a  committee,  and  if 
successful  the  committee  might  later  be  transformed  into  a  section.
