the  highest  ideals,  the  opportunity  is  offered  our  alumni  and  friends 
to  place  the  college  on  a  permanent  foundation  for  the  second  hundred 
years  of  its  history.  Every  alumnus  is  proud  of  the  college.  Each 
will  be  honored  by  its  increased  pre-eminence  among  scientific 
organizations,  and  by  the  status  which  pharmacy  must  assume  in 
the  development  of  modern  medical  practice.  Pharmacy  fixed 
upon  the  professional  plane  which  is  thus  assured,  will  continue  its 
great  service  to  the  medical  profession  and  to  humanity  at  large  and 
will  thus  increase  its  prestige  and  distinction. 
The  report  was  received  and  the  recommendations  considered 
seriatim. 
Many  of  the  members  took  part  in  the  discussion  that  followed 
the  consideration  of  each  recommendation  and  the  report  with  only 
several  slight  amendments  was  adopted  as  a  whole. 
Dr.  Robinson  asked  consideration  of  the  plan  proposed  at  the 
annual  meeting  of  enlisting  the  cooperation  of  those  graduates  of 
the  College  who  are  now  practicing  medicine.  He  thought  there 
were  about  250  of  these  graduates  in  Philadelphia  or  vicinity  alone. 
He  suggested  an  organization  be  formed  to  be  called  "The  Medical 
Section  of  the  Alumni  of  Philadelphia  College  of  Pharmacy.  The 
title  was  approved  and  it  was  believed  this  section  would  be  a  valu- 
able help  in  the  Centennial  efforts. 
There  was  some  discussion  as  to  the  continuance  of  the  General 
Committee  on  Centennial,  when,  on  motion,  it  was  voted  that  the 
committee  be  continued  as  an  Advisory  Committee.

ISOLATION  OF  THE  ACTIVE  PRINCIPLE  OF  THE 
THYROID  GLAND.* 
Among  the  achievements  of  biological  chemistry  the  isolation 
in  a  crystalline  form,  and  as  a  definite  chemical  body  of  the  blood- 
raising  principle  present  in  the  suprarenal  capsule  marks  a  distinct 
epoch,  and  the  investigations  to  which  adrenalin  has  since  its  dis- 
covery been  submitted  have  removed  the  veil  from  many  processes 
connected  with  the  life  of  the  organism.  Now  comes  the  news 
from  America  of  another  great  stride  forward  in  our  knowledge  of 
biology,  of  a  discovery  that  may  have  far-reaching  effects  on  thera-
