Pharmacy's  Unexplored  Field. 
By  Jos.  Weinstein. 
The  author  states  that  great  possibilities  await  pharmacists  in  the 
field  of  bacteriology,  whereby  they  can  prove  acceptable  co-workers 
with  the  physicians  and  demonstrate  thier  abilities  as  scientific  men. 
The  Evolution  of  "  Unofficial  Formulae." 
By  C.  Lewis  Diehl. 
The  object  of  this  paper  is  to  point  out  the  slender  material  upon 
which  the  earlier  efforts  to  secure  uniformity  in  preparations  of  the 
same  name  were  based ;  to  trace  the  evolution  of  the  earlier  collec- 
tion of  formulas  to  the  magnificent  collection  now  available  to 
pharmacists ;  to  reconcile  the  younger  members  of  our  profession 
with  conditions  of  imperfections  which  were  probably  far  more 
difficult  to  correct  in  the  past  than  they  are  at  the  present  time. 
Construction  of  Official  Preparations. 
By  H.  C.  Blair. 
The  claim  was  made  that  as  the  U.  S.  P.  is  intended  to  serve  as

for  manufacturers,  it  should  contain  formulas  that  are  simple,  plain 
and  as  exact  as  possible,  with  a  consideration  for  expedition  and 
expense.  The  paper  was  illustrated  with  samples  and  improved 
formulas  were  offered. 
Notes  on  Some  Official  Iodine  Solutions. 
By  F.  W.  Nitardy. 
The  following  modified  formula  was  presented  as  representing 
an  improvement  over  the  present  official  formula  for  tincture  of 
iodine :  Iodine,  70  Gin. ;  Potassium  iodide,  50  Gm. ;  Water,  35  c.c. -\ 
Alcohol,  a  sufficient  quantity  to  make  1000  c.c.  Introduce  the 
iodine,  potassium  iodide  and  water  into  a  graduated  flask  or  bottle, 
shake  until  completely  dissolved,  and  add  sufficient  alcohol  to  make 
the  finished  tincture  measure  1000  c.c. 
As  alcohol  is  not  the  active  constituent  of  this  preparation,  its 
value  is  in  no  way  reduced  by  the  introduction  of  3^  per  cent, 
of  water ;  while  the  saving  of  time  is  considerable  since  only  a
