in  particular  an  engraving  of  Harvey  demonstrating  his  theory  of 
the  circulation  of  the  blood  to  King  Charles. 
On  the  ground  floor  of  the  museum  is  shown  a  London  Pharmacy 
of  the  18th  century,  the  shop  front  of  which  is  the  original  of  the 
pharmacy  established  in  1798  by  John  Bell,  founder  of  the  Pharma- 
ceutical Society  of  Great  Britain. 
So  many  and  varied  and  of  such  interest  are  the  things  indexed 
that  one  longs  for  an  opportunity  to  visit  old  London  and  see  for 
himself  this  Historical  Medical  Museum.

Skin  Rashes  Following  the  Administration  of  Atophan. 
Skin  rashes,  similar  to  those  following  the  administration  of 
antipyrin,  are  not  uncommon  after  atophan  has  been  taken.  As  this 
drug  has  been  recommended  as  of  value  in  the  treatment  of  urticaria 
the  report  of  five  cases,  by  Phillips  of  Western  Reserve  University 
Medical  Department,  showing  the  occurrence  of  various  skin  rashes — 
purpura,  urticaria,  and  scarlatiniform  eruptions — is  timely. — Journal

Ozone. 
In  a  very  interesting  paper  on  the  bactericidal  action  of  ozone 
Jordan  and  Carlson  record  some  experiments  to  determine  the  value 
of  this  gas.  As  an  aid  to  the  destruction  of  bacteria  they  found  it 
of  little  or  no  use.  They  also  make  the  statement  that  it  has  no 
practical  value  for  room  disinfection.  This  statement  is  doubly 
interesting  because  ozone  has  been  recommended  by  interested  parties 
as  of  value  for  air  purification  of  occupied  rooms.  The  results 
of  the  author's  experiments  lead  them  to  believe  that  human  beings 
are  injuriously  affected  by  amounts  of  ozone  far  less  than  are  neces- 
sary to  produce  even  slight  bactericidal  effects. — Journal  A.M. A.,

Estimation  of  Acidity  of  Tincture  of  Iodine. 
A  definite  weight  of  the  tincture,  50  grams  for  instance,  is  mixed 
with  eight  times  its  weight  of  distilled  water  and,  after  standing 
one  hour,  filtered.   The  liquid  thus  freed  from  the  precipitated  iodine
