100  Pharmaceutical  Meeting. 
were  present.  Mr.  Kebler  said  that  no  doubt  Reinsch's  test 
was  the  best  for  general  purposes;  that  although  Marsh's  was  more 
difficult,  the  former  is  the  more  delicate.  He  also  referred  to  the 
presence  of  arsenic  in  potassium  carbonate  extracted  from  the 
residue  of  sheep  washings,  and  said  that  this  was  probably  due  to 
the  fact  that  the  sheep  were  washed  in  arsenical  dips. 
M.  I.  Wilbert  read  a  paper  on  "  Why  Popcorn  Pops."  (See  page 
77).  Mr.  LaWall  called  attention  to  the  fact  that  pieces  of  the 
grain  will  pop,  and  showed  a  hybrid  ear  of  popcorn  which  had 
been  planted  near  yellow  corn,  and  said  that  while  the  grains 
appeared  to  be  similar  in  most  particulars,  that  some  popped  and 
others  did  not.  Mr.  Kebler  said  that  under  certain  conditions  sweet 
corn  would  pop,  but  that  the  "  yellow  dent  "  would  not  pop  as  well 
as  the  "  crowfoot."  Mr.  Wilbert  said  that  field  corn  would  pop  and 
that  the  older  it  was  the  better.  He  also  stated  that  in  the  popping 
of  corn  it  was  necessary  that  the  outer  cells  be  dry  and  the  inner 
ones  moist.  Professor  Kraemer  drew  a  section  of  a  corn  grain  and 
referred  to  the  composition  of  the  different  parts  of  the  grain  and 
the  changes  which  take  place  on  the  application  of  heat. 
Professor  Remington  presented  life-sized  bust-portraits  of  Alfred 
B.  Taylor  and  Maurice  W.  Alexander,  and  said  that  Mr.  Wilbert 
had  prepared  short  sketches  of  each  of  these  men,  which  Mr. 
Wilbert  then  read.  The  portraits  were  pronounced  very  accurate 
likenesses,  and  remarks  on  the  life  and  work  of  these  men  were 
made  by  Messrs.  Hancock,  Wiegand,  Lowe,  Wilbert,  England  and 
Boring.  The  latter  offered  the  following  motion,  which  was  unani- 
mously adopted : 
"  In  view  of  the  great  services  rendered  to  pharmacy  by  Alfred 
B.  Taylor,  and  of  the  prominent  part  which  Maurice  W.  Alexander 
took  in  the  affairs  of  the  American  Pharmaceutical  Association;  and, 
furthermore,  in  view  of  the  desirability  of  the  Philadelphia  College 
of  Pharmacy  procuring  the  portraits  of  representative  men  whose 
lives  furnish  interesting  chapters  in  the  history  of  American  phar- 
macy, I  move'  that  a  special  vote  of  thanks  be  tendered  to  Professor 
Remington  for  presenting  the  portraits  of  these  men  to  the  college 
this  afternoon." 
Evan  T.  Ellis  presented  a  paper  on  "  The  Story  of  a  Very  Old 
Philadelphia  Drug  Store,"  which  was  read  by  title  and  referred  to 
the  Committee  on  Publication.  H.  K.
