Recent  Contributions  to  Pharmacy.  {A 
phate  again  precipitated  with  alcohol.  The  precipitate  is  collected 
and  dried  at  as  low  a  temperature  as  possible,  over  lime  or  sulphuric 
acid. 
The  resulting  powder  has  an  amorphous  appearance,  but  is  found 
under  the  microscope  to  be  crystalline.  The  yield  from  the  fore- 
going quantities  was  found  to  be  6  grammes.  The  portion  not  pre- 
cipitated by  alcohol  yields,  on  evaporation,  a  gelatinous  mass  con- 
taining calcium  glycerophosphate  not  precipitated  by  alcohol,  but 
precipitated  on  the  application  of  heat. 
The  glycerophosphates  of  sodium  and  potassium  have  only  been 
obtained  in  solution.  Those  of  magnesium,  lithium,  strontium, 
ferrous  and  ferric  iron  have  been  prepared.
