ing among  human  beings,  and  proved  successful. — New  York  Med.

RECENT  LITERATURE  RELATING  TO  PHARMACY. 
SOLUBILITY  OF  IODINE  AND  BROMINE  IN  WATER. 
F.  Dietze  [Pharm.  Zeit,  1898,  p.  327)  finds  the  solubility  of  iodine 
in  water  not  to  be  1  in  5,000,  but,  at  ordinary  temperatures,  it  is  1  in 
3,500  to  3,750,  and  at  300  to  be  1  in  2,200.  For  bromine  the  solu- 
bility is  correct  as  given  in  the  German  Pharmacopoeia,  viz.:  I  in  30.
