very  light  arms,  the  end  of  each  carrying  a  small  tissue,  black  on  one 
side  and  white  on  the  other,  when  the  device  is  put  in  the  light  it 
begins  to  revolve.  He  announced  (or  at  least  accepted)  that  this 
movement  resulted  from  the  action  of  light  striking  the  white  side 
and  being  absorbed  by  the  black  opposite.  After  investigating  it 
thoroughly,  however,  he  decided  that  it  was  not  light,  but  heat,  that 
made  the  object  move. 
Xow  we  know  that  force-driven  materials  are  nothing  marvel- 
ous. Electricity  moves  matter,  heat  moves  matter,  magnetism  moves 
matter.  There  is  nothing  marvelous  about  it,  unless  we  attempt  to 
get  at  the  origin  of  it  all,  then  all  is  a  marvel,  a  mystery/  At  a 
meeting  of  the  American  Pharmaceutical  Association  that  met  in 
Niagara  Falls  thirty-five  years  ago,  Professor  Carpenter,  the  famous 
English  physiologist,  was  visiting  Niagara  Falls.  We  invited  him  to 
give  a  lecture  before  the  Association.  He  had  a  friend  in  England 
renowned  in  a  different  line,  in  chemistry.  His  name  was  Crookes. 
These  two  friends,  it  has  been  stated  (if  memory  serves  correctly), 
became  interested  in  the  phenomena  of  spiritualism  and  concluded 
they  would  investigate  it  scientifically.  Reading  the  same  books, 
without  bias,  as  they  thought,  studying  the  problem  carefully,  each 
with  an  open  mind,  Carpenter  became  a  pronounced  opponent  of  the 
cult,  Crookes  a  devoted  spiritualist.  Possibly  my  memory  is  at  fault 
concerning  details,  possibly  my  informant  was  mistaken  in  his  nar- 
rative— it  matters  little,  the  text  remains  and  is  but  a  parallel  of  dis- 
cordant views,  good  men  hold  in  all  walks  of  life. 
This  is  what  I  ask  you  to  accept  in  the  direction  of  what,  as  an 
opinion  I  bring  before  you  today.  I  am  looking  at  the  problem  from 
one  angle.  Another  year  T  may  look  at  it  differently.  How  easy  it  is 
to  differ  from  one  another,  and  how  indiscreet  to  get  out  of  humor 
with  each  other.  We  do  not  agree  with  our  own  selves  after  an 
interval  of  time. 
Two  weeks  ago  I  sat  in  a  little  circle  of  men  whose  names  are 
well  known  throughout  the  country.  It  was  an  evening  dinner.  Dis- 
cussions arose,  first  one  thing  and  then  another.  Finally  I  was  called 
upon  to  say  something.  They  had  been  talking  on  different  problems 
connected  with  pharmacy  and  medicine.  I  said:  "Gentlemen,  I  am 
here  as  an  invited  guest,  as  you  know,  a  representative  of,  as  I  be- 
lieve, a  misunderstood,  ostracized  section  in  medicine.  I  have  for  a 
lifetime  given  my  time  and  study  largely  to  problems  that  concern  the
