1 66  Suggestions  for  National  Formulary.     j^™-  {?ar'ch!*'i9'2o: 
The  lists  should  include  all  N.  F.  and  all  important  and  widely- 
demanded  chemicals,  and  must  be  kept  strictly  confidential  by  the 
Revision  Committee.  Purchases  by  jobbers  and  pharmaceutical 
manufacturers  are  suggested  because  these  records  are  readily 
available,  whereas  output  could  not  be  obtained  because  of  the  di- 
versions of  a  lot  of  chemicals  to  innumerable  uses.  A  period  of  not 
less  than  two  years  should  be  considered  as  a  basis  for  collection  of 
data,  as  this  is  required  to  obtain  an  average. 
Basis  of  decision:  The  items  on  the  individual  lists  should  be 
placed  in  classes  based  upon  their  dosage.  Where  output  or  pur- 
chase of  non-official  chemicals  is  greater  than  the  output  of  N.  F. 
chemicals  of  the  same  general  dosage,  the  non-official  chemicals 
should,  be  placed  in  a  class  to  be  considered  for  admission  to  the 
N.  F.  Then  the  results  of  classification  of  all  of  the  individual  lists 
should  be  harmonized  and  chemicals  thus  selected  should  be  se- 
riously considered  for  admission  to  the  N.  F. 
In  the  Case  of  Crude  Drugs:  Data  for  basing  decision  for  admis- 
sion.— Lists  of  purchases  of  crude  drugs  by  larger  drug  trade  job- 
bers and  pharmaceutical  manufacturers  should  be  obtained.  The 
output  of  a  collecting  house  should  not  be  considered  unless  the  out- 
put is  solely  for  medicinal  purposes  or  the  list  specifies  only  the  part 
of  the  output  which  was  diverted  to  medicinal  purposes.  The  lists 
should  include  all  N.  F.  and  all  important  and  widely  demanded 
crude  drugs  and  must  be  considered  strictly  confidential  by  the  Re- 
vision Committee.  Purchases  by  jobbers  and  pharmaceutical  manu- 
facturers are  suggested  for  the  same  reasons  as  mentioned  under 
"chemicals"  above.  A  period  of  not  less  than  two  years  should  be 
considered  as  a  basis  for  collection  of  data,  in  order  to  obtain  an 
average,  because  some  supplies  of  crude  drugs  are  purchased  quite 
infrequently. 
Basis  of  decision:  As  mentioned  above,  under  "chemicals." 
In  the  Case  of  Pharmaceutical  Products:  Data  for  basing  de- 
cision for  admission. — Lists  of  purchases  by  jobbers  and  output  of 
manufacturers.  The  lists  should  include  all  N.  F.  and  all  important 
and  widely  demanded  products,  and  must  be  considered  strictly  con- 
fidential by  the  Revision  Committee.  Purchases  by  jobbers  and 
output  of  manufacturers  are  suggested,  because  these  records  are 
readily  available.  A  period  of  not  less  than  two  years  is  desired  for 
the  collection  of  data,  because  the  number  of  lots  of  any  one  prepara- 
tion made  up  during  one  year  is  too  small  for  average  purposes.
