Tincture  of  Iodine. — C.  Courtot  (Journ.  de  Pharm.  et  de 
Chim.,  1010,  Nr.  67)  presents  a  study  of  the  changes  that  take 
place  in  tincture  of  iodine  and  concludes  that  the  products  formed 
are  hydriodic  acid,  acetaldehyde  and  acetic  ether.  The  reactions 
taking  place  he  outlines  as  follows :  Through  the  action  of  iodine 
on  alcohol  hydriodic  acid  and  acetaldehyde  are  produced;  the  latter 
is  decomposed  by  iodine  in  the  presence  of  water  to  acetic  acid, 
which,  reacting  on  the  alcohol,  produces  acetic  ether  {Pharm. 
Ztg.,  Berlin,  1910,  v.  55,  p.  346). 
Volatile  Oils. — Hill  and  Umney  present  a  number  of  mono- 
graphs for  volatile  oils  which  it  is  proposed  to  submit  for  inclusion 
in  the  coming  edition  of  the  British  Pharmacopoeia  (Pharm.  J., 
London,  1910,  v.  30,  pp.  177-181). 
The  Che  mist  and  Druggist  (1910,  March  12,  pp.  94-96)  presents 
a  comprehensive  comparative  table  of  data  on  essential  oils  as 
propounded  by  different  authors,  British  Pharmacopoeia,  Squire's 
Companion,  Hill  and  Umney,  Parry's  Essential  Oils,  and  others, 
the  object  being  to  show  at  a  glance  the  points  upon  which  there 
is  agreement  and  disagreement.

possible  untoward  effect  resulting  from  the  use  of  such  preparations

and  complete  blindness  following  the  use  of  orsudan  in  a  case  of 
syphilis.  Also  calls  attention  to  three  cases,  which  recently  came 
under  his  notice,  in  which  blindness  was  caused  by  soamin  (Brit. 
Med.  Journ.,  1910,  v.  1,  p.  599). 
The  Dangers  of  Orsudan  and  Soamin. — An  editorial  in  the 
Pharmaceutical  Journal,  1910,  v.  30,  p.  387,  calls  attention  to  the 
numerous  reports  that  have  been  published  recently  on  the  possible 
dangers  that  might  accrue  from  the  use  of  orsudan  and  soamin.
