MAGMA  BISMUTHI. 
By  S.  Bertha  Muller,  P.D., 
Assistant  Pharmacist  at  the  German  Hospital,  Philadelphia. 
In  recent  years  Magma  Bismuth  has  become  quite  popular,  so 
much  so  that  it  was  deemed  advisable  to  make  the  preparation

With  that  end  in  view  several  formulas  have  been  proposed  and 
duly  tried  out,  but  in  our  experience  have  not  proved  generally 
satisfactory.
