become  insensible  from  the  inhalation  of  illuminating  gas.  He  gives 
several  drops  on  sugar^  the  patients  soon  revive,  and  in  a  very  short 
time  are  again  able  to  work. — Archiv  der  Pharm.,  1885,  p.  716. 
Metallic  Magnesium  in  Fireworks. — The  addition  of  2J  per  cent,  of 
powdered  magnesium  entirely  conceals  the  green  flame  produced  by 
barium  salts,  giving  them  a  bright  white  light,  similar  to  the  electric 
light ;  to  the  strontium  flame  it  imparts  an  extraordinary  brilliancy. 
The  following  formulas  yield  good  results :  White  Light. — Shellac  1 
part,  nitrate  of  barium  6  parts ;  add  2J  per  cent,  powdered  magne- 
sium, lied  Lire. — Shellac  1  part,  nitrate  of  strontium  5  parts;  add 
2 J  per  cent,  powdered  magnesium.  The  salts  are  mixed  with  the 
shellac,  the  mass  fused  and  powdered  ;  then  the  magnesium  is  added.

Sublimation  of  Oxalic  ^cic?.— According  to  M.  Siegfried,  oxalic  acid 
sublimes  at  several  degrees  below  100°C. 
lodol,  a  NeiD  Antiseptic. — lodol  manufactured  by  Silber  and  Ciami- 
cina  in  Rome  has  been  used  in  the  surgical  clinics  of  Mazzoni.  Dr. 
Mazzoni  finds  iodol  free  from  the  disagreeable  odor  of  iodoform,  and 
does  not  produce  symptoms  of  intoxication.  It  is  a  powerful  anti- 
septic, aiding  the  formation  of  healthy  granulations  and  occasionally 
producing  local  anaesthesia.  Iodol  is  prepared  from  volatile  animal 
oil  by  precipitating  the  pyrrol  with  a  solution  of  iodine  in  iodide  of 
potassium,  thus  forming  pyrrol  tetraiodide,  or  iodol.  It  is  a  brown 
powder,  capable  of  being  heated  to  100°C.  without  decomposition ; 
at  a  higher  temperature  it  is  decomposed,  giving  off  iodine  vapors  and 
leaving  a  voluminous  coke  as  residue.  Iodol  is  very  slightly  soluble 
in  water,  and  readily  soluble  in  strong  alcohol,  but  precipitated 
again  on  adding  water.  The  addition  of  glycerin  to  the  alcoholic 
solution  does  not  precipitate  it.  Ether  and  chloroform  also  dissolve 
it.  Tests :  Sulphuric  acid  produces  a  green  color,  and  by  heating  the 
alcoholic  solution  to  which  nitric  acid  has  been  added  a  bright  red  color 
is  produced. — Rundschau,  xi,  p.  668. 
Syrup  of  Hippurate  of  Calcium. — ^  Acid  hippuric,  pure,  1  ;  milk 
of  lime,  q.s.;  hot  water,  20  cc  :  sugar  24;  spirit  of  limon,  0'15. 
To  a  portion  of  the  water,  heated  to  75  or  80°C.,  add  the  acid 
and  milk  of  lime;  agitate,  and  test  from  time  to  time  with  test  paper, 
until  the  solution  is  slightly  alkaline;  add  balance  of  water  and  sugar 
and  heat  over  a  gentle  fire.  The  solution  of  hippurate  of  calcium  is 
the  same  without  the  sugar. — Repertoire  de  Pharmacie,  1885,  p.  434.
