By  Otto  Raubenheimer. 
The  author  proposed  a  better  title  and  an  improved  formula  for 
Bismuthi  Oxidum  Hydratum  N.  F.,  and  gave  practical  experiments 
and  stoichiometric  calculations.

Compound  Solution  of  Phosphate  of  Soda,  U.  S.  P. 
By  H.  G.  Posey. 
The  author  gives  the  results  of  experiments  to  overcome  the 
tendency  of  this  preparation  to  deposit  crystals ;  also  to  avoid  the: 
growth  of  fungi  therein.  He  recommends  that  the  quantity  of 
citric  acid  be  increased  to  260  Gm.,  and  that  solution  of  both  the 
salts  and  the  acid  be  affected  by  aid  of  a  water  bath  instead  of 
continued  trituration  in  a  mortar,  as  directed  by  the  Pharmacopoeia,, 
and  that  the  resultant  product  be  filtered  while  yet  hot,  thereby 
producing  a  beautiful,  clear  liquid,  which  will  compare  favorably 
with  the  many  sodium  phosphate  solutions  now  on  the  market, 
and  will  be  a  credit  instead  of  a  discredit  to  our  Pharmacopoeia. 
Fluidglycerates. 
By  George  M.  Beringer. 
The  author  suggests  a  new  class  of  liquid  galenicals — 1  c.c.  to 
represent  1  Gm.  of  the  drug  with  glycerin  replacing  alcohol  as 
a  solvent.  A  general  formula  with  method  of  manipulation  in 
manufacturing  these  products  is  given  together  with  the  results 
of  experimentation  upon  a  number  of  drugs,  the  results  being  con- 
firmed by  assays  of  the  finished  products.
