Di-iodo-thiophenc  is  proposed  by  E.  Spiegler  as  a  substitute  for 
iodoform;  it  has  been  found  effective  in  preventing  pus-formations. 
It  has  the  formula  C4H2T2S  and  contains  75-5  per  cent,  iodine  and 
9- 5  per  cent,  sulphur  directly  in  combination  with  carbon;  it  forms 
tabular  crystals,  easily  volatilized,  melting  point  40*5°  C.  The 
odor  is  stated  to  be  rather  aromatic ;  it  is  insoluble  in  water, 
slightly  soluble  in  cold  alcohol,  but  easily  soluble  in  warm  alcohol, 
ether  and  chloroform.  A  ten  per  cent,  gauze  is  made  by  saturating 
gauze  with  the  following  solution  :  Di-iodo-thiophen  50-0,  alcohol 
and  ether,  of  each  5000,  glycerin  10  0  ;  an  addition  of  2-0-3  0  of  a 
saturated,  alcoholic  solution  of  saffranine  is  recommended  to  indi- 
cate the  uniform  distribution  of  the  solution  upon  the  gauze. 
Sodium  thiophene-sulphonaie. — C4H3SNaS03is  superior  to  naphthol 
in  prurigo  if  applied  in  the  form  of  a  five  to  ten  per  cent,  ointment 
(lanolin  and  vaselin  equal  parts  as  the  base).  This  compound  is  a 
white  crystalline  powder  containing  33  per  cent,  sulphur  of  which 
one  half  is  directly  combined  with  carbon.  The  lead  salt  can  be 
used  in  the  same  manner?  but  it  will  cause  a  burning  sensation  last- 
ing for  several  minutes  with  some  individuals. — (Therap.  Monats-

Nitrous  acid  as  a  disinfectant  had  been  proposed  some  years  ago 
because  of  its  peculiar  property  of  being  an  oxidizing  as  well  as  a 
reducing  agent;  H.  Borntrager  employs  the  following  combination 
containing  20  per  cent,  sodium  nitrite :  One  part  sodium  nitrite  and 
one  part  gypsum  are  melted  together,  after  cooling  the  mass  is  pow- 
dered and  preserved  in  well-stoppered  receptacles.  Two  parts  sodium 
bisulphate  and  one  part  gypsum  are  also  melted  together  and,  after 
cooling,  powdered.  Both  powders  are  now  mixed  and  preserved  in 
dry  and  tightly -stoppered  containers.  If  this  powder  be  thrown  into 
water  or  substances  to  be  disinfected,  a  uniform  evolution  of  nitrous 
acid  takes  place  which  rapidly  destroys  foul  odors. — Pharm.  Central-

Kola-nut. — An  analysis  by  Heckel  and  Schlagdenhauffen  was 
published  in  the  American  Journal  of  Pharmacy,  1884,  page  170. 
It  was  at  first  thought  that  the  medicinal  effect  depended  entirely 
upon  the  presence  of  caffeine,  although  Heckel  found  that  the  residue
