Basis  of  decision  for  admission:  Same  as  above  under  "chemi- 
cals." 
In  choosing  the  manufacturers  and  jobbers  for  cooperation  in 
this  plan,  efforts  should  be  made  to  have  all  sections  of  the  United 
States  and  its  possessions  represented. 
This  plan  is  dependent  entirely  upon  the  acquisition  of  the  co- 
operation of  drug  manufacturers,  collectors,  and  jobbers. 
Cooperation  may  possibly  be  obtained  from  many  manufacturers, 
collectors,  and  jobbers  upon  formal  request.  Information  offered 
must  necessarily  be  considered  strictly  confidential  and  public  ac- 
knowledgment of  the  assistance  rendered  should  be  made  by  the 
Revision  Committee.

A  broad  scientific  plan  of  ascertaining  the  advisability  of  de- 
leting items  from  the  N.  F.  is  also  urgently  needed.  Such  a  plan 
would  result  from  the  adoption  of  the  above-mentioned  plan  for 
ascertaining  the  need  for  admitting  items,  as  those  N.  F.  items  en- 
joying onlv  small  output  by  manufacturers  and  small  purchases  by 
jobbers,  in  comparison  with  the  items  being  heavily  manufactured 
and  purchased,  would  naturally  become  candidates  for  deletion. 
METHOD  OF  KEEPING  THE  N.  F.   WITHIN  EASHvY  HAN  DAB  LE  SIZE- 
The  less  potent,  less  important,  and  less  commonly  used  sub- 
stances could  be  continued  in  the  following  edition,  merely  by  name 
and  by  referring  to  the  previous  edition  for  descriptions  of  the 
methods  and  tests.  Any  required  additional  tests,  or  modifications 
of  previous  tests  could  be  included  under  the  name  in  the  following 
edition  and  any  deletions  of  previous  tests  could  also  be  recorded 
there. 
CHEMICALS. 
Manganese  Glycerophosphate  Soluble. — This  product  consists  of  a 
mixture  of  70  parts  of  Manganese  Glycerophosphate  and  30  parts  of 
citric  acid.  Manufacturers  of  Manganese  Glycerophosphate  ob- 
ject to  mixing  their  product  with  citric  acid,  therefore  this  product 
is  not  generally  available.  A  formula  for  its  manufacture  should 
be  included  in  the  N.  F.  and  the  pres€'.nt  monograph  for  this  product 
should  be  adapted  to  plain  Manganese  Glycerophosphate,  which 
also  should  be  admitted  to  the  N.  F. 
Quinine  Formate. — The  use  of  this  substance  is  rapidly  increasing 
and  standards  should  be  established  for  purposes  of  uniformity.
