observations  and  his  readiness  of  eomnninicating  knowledge  from  his 
extensive  and  varied  experience,  were  commented  on  by  several  of  those 
present. 
Mr.  Boring  made  some  remarks  in  relation  to  fiuld  extract  of  guarana^ 
as  made  by  himself  with  a  menstruum  of  alcohol,  glycerin  and  water. 
When  first  prepared  it  was  brilliantly  transparent  and  free  from  deposit, 
but  after  a  time  a  sediment  was  observed  which,  when  loosened,  was  solu- 
ble in  a  menstruum  rendered  alkaline  with  ammonia. 
Mr.  Robbins  stated  that  a  menstruum  free  from  glycerin,  made  of  equal 
weights  of  alcohol  and  water,  was  better  and  that  no  deposit  occurred  when 
it  was  used. 
Mr.  W.  B.  Thomjjson  urged,  and  the  members  present  coincided  with 
him,  that  a  much  larger  number  of  the  members  of  the  College  should 
attend  these  meetings  and  bring  forward  whatever  subjects  interested  them 
personally  ;  this  would  tend  greatly  to  enhance  the  interest  and  usefulness 
of  these  meetings. 
Dr.  L.  Wolff  made  some  remarks  in  regard  to  the  antiseptic  powers  of 
salicylic  acid  and  other  substances.  His  experience  was  that  salicylic  acid 
was,  at  least  in  some  cases,  better  than  phenol.  Many  of  the  substances 
experimented  with  proved  to  be  valueless  for  this  purpose. 
A  member  queried  as  to  the  cause  of  the  appearance  of  a  violet  color  in 
iodide  of  potassium.  It  was  the  general  opinion  tliat  it  was  due  to  decom- 
position of  the  salt,  a  small  quantity  of  free  iodine  only  being  required  to 
discolor  a  great  deal  of  the  salt. 
Dr.  Wolff  suggested  that  a  correct  and  ready  method  of  determining 
the  value  of  pepsin  would  be  an  excellent  subject  for  some  member  to 
report  on  next  fall. 
There  being  no  further  business,  the  meeting  adjourned  until  the  third 
Tuesday  of  October.  T.  S.  Wiegand,  Registrar.

Philadelphia  College  of  Pharmacy.— A  year  ago  this  College  for- 
warded to  Melbourne,  Australia,  a  collection  of  indigenous  American  drugs 
for  the  exhibition  which  has  been  held  there  during  the  past  months.  The 
collection,  which  was  similar  to  the  one  forwarded  to  the  last  Paris  exijosi- 
tion,  attracted  considerable  attention,  and  has  been  honored  with  an  award 
of  the  first  degree  ;  it  has  been  presented  to  the  Pharmaceutical  Society  of 
Victoria.
