8.  Has  the  presence  of  oxydases  in  the  materials  any  influence  on 
the  quality  of  galenicals? 
9.  Is  it  possible  and  desirable  to  give  in  the  official  regulations 
physiological  as  well  as  chemical  methods  for  the  analysis  of 
galenicals  ? 
10.  Can  it  be  justified  that  regulations  or  requirements  for  medi- 
cines should  be  changed  on  other  than  medical  grounds? 
11.  A  uniform  international  agreement  for  establishing  uniform 
methods  in  the  preparation  of  galenicals  should  be  made  after  a 
comparative  examination  of  the  various  processes.

Subjects  Introduced  for  Discussion. 
1.  In  how  far  would  it  be  possible  to  shorten  the  chemical  mono- 
graphs of  the  Pharmacopoeia  in  a  reasonable  way? 
2.  What  requirements  should  be  established  for  the  quality  of 
the  glass  used  in  pharmacy? 
3.  Codification  of  the  requirements  of  purity  necessary  for

7.  Comparative  examination  of  the  qualitative  and  quantitative 
methods  of  testing  pepsin,  trypsin,  and  other  proteolytic  or  pepto- 
-  lytic  ferments. 
8.  Is  the  action  of  pepsin  identical  to  that  of  chimosin  or  not  ? 
9.  The  occurrence,  the  significance,  and  the  tracing  of  ferments 
in  animal  excreta. 
10.  The  conduct  of  albuminoids  in  an  aqueous  solution  by  the  side 
of  salts,  and  in  connection  with  the  reaction  of  the  medium. 
11.  The  desirability  and  possibility  of  a  codification  of  clinical  and 
chemical  methods  of  analysis.
