be  given  with  infusions  of  remedies  containing  tannin.

and  with  solution  of  iodide  of  potassium  only  by  taking  the  iron 
syrup  afterwards.

LIQUID  SULPHUROUS  ANHYDRIDE. 
By  M.  Sestini. 
M.  Sestini  (Bull,  de  la  Soc.  Chem.)  has  published  some  re- 
searches on  liquid  anhydrous  sulphurous  acid  as  a  solvent. 
If  three  decigrams  of  white  phosphorus  is  put  in  contact  with 
three  cubic  centimetres  of  this  acid,  it  diminishes  in  volume  gradu- 
ally and  the  liquid  assumes  a  light  yellow  color.  When  the  sealed 
tube  is  put  in  the  dark  neither  the  liquid  nor  the  phosphorus  are 
luminous.  After  some  days,  having  opened  the  tube,  the  liquid 
becomes  again  phosphorescent  in  the  dark  and  leaves,  on  evapora- 
tion, a  small  residue  of  white  phosphorus. 
Iodine  is  slightly  dissolved,  causing  a  reddish  yellow  color. 
Bromine  dissolves  in  sulphurous  acid  ;  sulphur,  on  the  contrary, 
is  very  little  soluble  in  this  liquid. 
If  a  few  drops  of  anhydrous  sulphurous  acid  are  thrown  into 
a  tube  containing  normal  nitric  acid  a  white  crystalline  pro- 
duct is  obtained,  as  in  the  lead  chambers,  and  disengages  nitrous 
vapors. 
A  mixture  of  one  volume  of  sulphurous  acid  with  three  vol- 
umes of  bisulphide  of  carbon  by  prolonged  contact  (20  to  25 
days)  became  a  homogeneous  liquid.
