AVe°eURi*,       }   Minutes  of  Pharmaceutical  Meetings.  533 
Donations  to  the  Library  and  Cabinet  being  in  order,  Prof.  Maisch  presented 
to  the  Library  a  Catalogue  published  by  the  Department  of  the  Interior,  called 
A  Circular  of  Information  of  the  Bureau  of  Education.  The  thanks  of  the  meet- 
ing were  directed  to  be  forwarded  by  the  Registrar. 
Samples  of  Myrcia  acris,  Eucalyptus  globulus,  bark  and  oil  of  E.  globulus* 
were  presented  by  Jas.  T.  Shinn,  from  W.  Neergaard,  of  New  York:  A  speci- 
men of  apomorphia  was  also  exhibited,  and  it  was  stated  that  one  grain  placed 
on  the  tongue  would  be  followed  by  emesis  in  six  minutes.  1-1  Oth  of  a  grain 
administered  hypodermically  produced  the  same  effect. 
Prof.  Maisch  presented  to  the  College  cabinet  a  beautiful  specimen  of  the 
leaves  and  fruit  of  Chondodendron  tomentosum,  which  had  been  sent  by  Dan- 
iel Hanbury,  of  London.  The  paper  illustrated  by  the  specimens  was  repub- 
lished in  the  American  Journal  of  Pharmacy,  October,  1873. 
Richard  V.  Mattison  read  a  paper  on  Pancreatin,  in  which  he  detailed  a  pro- 
cess of  preparation  analogous  to  that  of  E.  Scheffer's  for  making  Pepsin.  The 
solution  of  Pancreatin  was  found  to  possess  the  property  of  emulsifying  cod 
liver  oil  readily.    The  paper  will  be  found  in  full  in  this  number. 
Prof.  Maisch  read  an  article  from  W,  M.  Rice  on  Emulsifying  Cod  Liver  Oil, 
in  which  the  writer  used  tragacanth  as  the  medium.  A  sample  was  exhibited 
made  by  his  process  in  which  the  taste  of  the  oil  was  thoroughly  disguised.  A. 
discussion  here  arose  as  to  what,  in  the  opinion  of  the  members  present,  constitu- 
ted a  good  emulsion.  J  as.  T.  Shinn  advocated  thin  emulsions,  and  did  not  favor 
the  dispensing  of  thick  emulsions,  for  he  thought  that  the  patient  could  readily 
incorporate  the  water  and  oil  that  had  partially  separated- by  standing,  and  would 
prefer  to  do  it  rather  than  take  a  thick  emulsion.  Jos.  P.  Remington  stated 
that  he  had  made  and  dispensed  a  cod  liver  oil  jelly,  made  on  the  same  princi- 
ple as  the  emulsion  of  Mr.  Rice's,  and  the  formula  would  be  found  at  page  175 
of  the  present  volume  of  the  Journal,  extracted  from  the  London  Pharmaceu- 
tical Journal  of  March  8th,  1873.  This  jelly  seemed  to  give  satisfaction  wher- 
ever it  was  used  ;  but  it  was  necessary  to  use  only  tise  finest  and  freshest  oil. 
Prof.  Maisch  spoke  of  the  use  ot  alkaline  solutions  in  emulsions,  and  of  the  ten- 
dency of  such  to  spoil  if  kept  too  long  and  become  disagreeable  to  the  taste. 
A  member  wished  to  know  of  Mr.  Rice  whether  a  smaller  quantity  of  traga- 
canth could  not  be  used  in  the  formula. 
To  this  F.  Stryker  Boisnot  replied  that  both  Mr,  Rice  and  himself  had  tried 
various  proportions,  and  found  that  they  could  not  useless. 
R.  Y.  Mattison  said  that  gum  arabic  and  sugar  had  proved  to  be  the  best  in 
his  experience  for  thick  emulsions,  and  solution  of  pancreatin  for  thin  one-. 
Dr.  A.  W.  Miller  read  an  interesting  paper  on  Cosmolin,  and  exhibited  a 
number  of  specimens.  He  said  that  cosmolin  amounted  to  nothing  more  than 
paraffin  dissolved  in  what  is  technically  termed  neutral  oil.  Me  showed  a  sam- 
ple made  in  this  way,  which  resembled  cosmolin  very  closely.  It  could  be  sold 
at  a  fair  profit,  if  made  in  this  way,  for  25  cents  per  pound,  whilst,  cosmolin 
costs  three  times  that.  His  paper  will  be  found  elsewhere.  President  Wil- 
liamson remarked  that  petroleum,  paraffin,  cosmolin,  &c  &c,  had  all  come  up 
since  his  day;  but  even  in  old  times  they  had  petroleum.  An  article  called 
Seneca  Oil  used  to  sell  freely  for  I]  d.  per  ounce,  which  was  petroleum  collect-
