Its  melting  point  is  very  close  to  that  of  the  original  hydro- 
thymoquinone ;  so  tests  were  made  to  establish  its  identity.  The 
hydroquinone  dissolves  slowly  in  5  per  cent,  sodium  hydroxide  with 
a  red-brown  color.  The  dibenzoate  was  unacted  upon  during  the 
same  time.  With  a  little  thymoquinone,  the  hydroquinone  in  alco- 
liol  evaporated  leaving  a  purple  film  and  purple  crystals.  The  diben- 
zoate evaporated,  leaving  yellow  crystals  of  unchanged  quinone, 
"but  no  quinhydrone  color  at  all.  Finally  a  mixture  of  the  two  was 
melted  along  with  the  constituents  on  the  same  thermometer :

This  title  has  been  chosen,  not  because  it  fits  the  paper  through- 
out, but  because  a  number  of  the  references  in  it  relate  to  such  serv- 
ices. I  hope  you  will  not  expect  my  feeble  effort  to  entertain;  it 
may  not  even  present  a  formidable  thought  that  can  be  applied  with 
profit,  and  perhaps  the  brevity  of  the  paper  will  please  you  most. 
However,  there  is  a  reason  for  the  presentation,  which  has  been 
prepared  in  response  to  a  request  by  Dean  La  Wall,  to  say  something 
on  the  occasion  of  a  monthly  Faculty  meeting,  and  came  just  after 
looking  over  the  report  of  the  Convention  of  the  American  Pharma- 
ceutical Association  in  New  Orleans,  in  1891.  It  impressed  me 
with  the  indirect  services  rendered  by  pharmacy  and  pharmacists, 
and  that  which  has  been  stated  in  many  ways  : — we  receive  by  giving, 
and  in  real  service  both  the  giver  and  recipients  share.    In  this  way
