practical  and  manipulative  work  of  the  three  main  lines  of  study 
represented  in  the  college. 
We  hope  thus  to  do  our  part  in  turning  out  young  men  able  to 
enter  upon  the  practice  of  pharmacy  as  a  profession  and  not  merely 
ready  to  open  a  store  and  cater  to  the  public  and  its  whims  as  the 
corner  grocer  does. 
And  now  young  men  of  the  class  of  1894,  we  have  come  to  the 
last  word.  We  have  endeavored,  as  far  as  lay  in  our  power,  to 
assist  you  in  getting  your  pharmaceutical  education,  and  have 
brought  you  to  the  point  when  you  are  ready  to  launch  out  with 
your  certificate  of  qualification  to  practice  your  profession.  It  is 
for  you  to  say  whether  you  will  practice  it  in  a  manly,  self-respecting 
way,  or  perpetuate  and  intensify  the  evils  of  which  I  have  spoken 
by  turning  your  back  upon  your  opportunities,  and  forgetting  your 
birthright  as  graduates  of  the  Philadelphia  College  of  Pharmacy. 
That  you  may  make  such  use  of  your  powers  as  will  make  us 
proud  of  you  and  your  record  in  the  future,  is  the  ardent  wish  and 
hope  of  your  Alma  Mater. 
THE  MANUFACTURE  OF  CALOMEL  IN  JAPAN.1 
By  Edward  Divers,  M.D.,  F.R.S. 
Introductory . — Calomel,  in  the  form  common  in  England  and  all 
countries  under  Western  civilization,  is  now  extensively  used  and  is 
even  manufactured  in  Japan,  under  the  name  of  kanko.  But  mer- 
curous  chloride  is  also  largely  used  there  under  the  name  of  "  light 
powder,"  keifnn  (Chinese,  kingfun),  in  another  and  very  much  older 
form,  which  is  of  signal  purity,  and  made  by  a  simple  process  as  yet 
quite  unknown  in  Europe.  I  witnessed  this  interesting  process 
from  beginning  to  end  some  years  ago,  and  now  make  this  publica- 
tion of  it  to  the  Society,  with  full  permission  of  the  proprietor  of  the 
works  I  visited,  Mr.  H.  Kokubu,  who  has  aided  me  in  every  way  he 
could,  and  notably  with  drawings,  some  of  which  illustrate  this 
paper. 
Historical. — According  to  Terajima  Kokyo  and  Ono  Ranzan, 
writers  who  lived  in  the  last  century,  the  first-named  perhaps  a  little 
earlier,  calomel  was  known  in  Japan  as  far  back,  at  least,  as  the
