Mr.  Raubenheimer  said  that,  as  already  mentioned  in  his  paper, 
references  to  the  medicinal  virtues  of  clay  could  be  traced  back  to 
the  writings  of  Dioscorides. 
Mr.  George  M.  Beringer  stated  that  the  British  Pharmaceutical 
Codex  had  increased  the  percentage  of  glycerin  in  the  cataplasm  of 
kaolin,  and  said  that  a  practical  difficulty  was  thus  introduced,  in 
that  a  smeary  mixture  resulted. 
Professor  Remington,  in  commenting  on  the  paper,  said  he  did 
not  imagine  that  a  clay  poultice  could  form  the  subject  of  such  a 
classical  paper.  He  said  that  the  principal  difficulty  in  making  the 
cataplasm  of  kaolin  was  that  of  getting  kaolin  having  uniform 
absorptive  property,  and  that  it  was  not  a  question  of  the  proportion 
of  the  different  components,  as  in  one  instance  the  product  Would 
be  crumbly  and  in  another  more  or  less  liquid.  He  therefore 
claimed  that  there  should  be  a  test  to  determine  the  relative  glycerin- 
absorption  power  of  the  kaolin,  or  a  purity  rubric  for  kaolin. 
Prof.  Henry  Kraemer  read  a  paper  on  <e  The  Centenary  of 
Charles  Darwin"  (see  p.  196). 
Prof.  E.  Fullerton  Cook  followed  with  some  notes  on  "  Drug 
Store  Conveniences,"  which  will  be  published  in  a  later  issue  of  the 
Journal.  In  this  connection  he  exhibited  a  vapor-alcohol  stove 
which  has  the  advantage  of  giving  a  sustained  moderate  heat  in  the 
presence  of  draughts  and  is  thus  adapted  for  those  operations  where 
a  comparatively  low  temperature  is  required. 
A  cordial  vote  of  thanks  was  tendered  the  speakers  of  the  after- 
noon. 
MARCH  PHARMACEUTICAL  MEETING. 
The  stated  pharmaceutical  meeting  was  held  Tuesday,  March 
16,  with  George  M.  Beringer,  a  member  of  the  Board  of  Trustees, 
presiding. 
Joseph  W.  England  read  a  brief  paper  giving  a  review  of  the 
literature  relating  to  the  "Enzymes  of  Cow's  Milk"  (see  p.  177). 
In  commenting  upon  the  paper  Prof.  Chas.  H.  LaWall  said  that 
he  had  been  conducting  some  experiments  with  reference  to  the 
enzymes  in  condensed  milks,  and  found  that  they,  particularly  those 
condensed  in  vacuo,  gave  a  positive  reaction  with  Dupouy's  test  and 
a  negative  one  with  the  Wilkinson  and  Peters  method,  which  showed 
that  an  intermediate  temperature  had  been  employed  in  their  prepara- 
tion. Mr.  Beringer  remarked  that  the  manufacturers  are  beginning 
to  take  cognizance  of  the  presence  of  the  enzymes  in  milk.
