Paraffin  Oil  is  said  to  be  a  Dew  adulterant  for  cod  liver  oil.  It 
can  be  recognized  by  saponification,  paraffin  does  not  saponify. — Ibid., 
xxv,  page,  792. 
Antipyrine  as  a  styptic. — Henocque  and  Huchard  have  used  anti- 
pyrine  for  bleeding  from  the  nose  and  on  wounds  on  the  hand  and 
fingers.  They  applied  0.5  grams  by  dusting  on  the  wounds. — Ar- 
ehivder  Pharmacie,  Dec.  1886,  page,  1027. 
Ointment  of  potassium  iodide. — To  mix  solutions  of  iodide  of  po- 
tassium with  petrolatum  the  Sud  Deutsche  Apotheker  Zeitung  recom- 
mends the  addition  of  a  small  quantity  of  lanolin.  The  ointment  is 
quickly  made,  is  smooth,  and  does  not  separate  even  after  standing  a 
long  time. 
Urethane  as  an  antidote  to  Strychnine,  Picrotoxin  and  Resorcin. — 
Prof.  Aurep  experimented  on  animals  with  urethane  and  found  it  to  be 
antagonistic  to  and  a  counter-poison  for  strychnine,  picrotoxin  and  res- 
orcin. Urethane  is  equally  as  good  as  chloral  and  is  not  dangerous, 
as  large  doses  can  be  taken  without  affecting  the  circulation  or  respir- 
ation. To  judge  from  the  effect  on  dugs  it  would  require  from  8  to  12 
grams  of  urethane  to  overcome  strychnine  poisoning  in  a  human  be- 
ing.— Ph.  Post,  xix  page  726. 
New  reaction  for  Hydrocyanic  acid. — To  the  suspected  liquid  is 
added  nitrite  of  potassium  and  ferric  chloride  acidulated  with  sulphu- 
ric acid  and  heated  to  near  the  boiling  point.  After  the  mixture  has 
cooled  the  iron  is  precipitated  by  ammonia  and  filtered.  The  filtrate 
is  tested  for  potassium  nitro-prussiate  with  colorless  solution  of  sul- 
phide of  ammonium.  In  a  dilution  of  1  part  of  hydrocyanic  acid  to 
312,500  parts  of  water  a  distinct  blueish-green  coloration  is  produced. 
— Ph.  Post,  xix  page  740. 
Osmic  acid. — Dr.  Schapiro  uses  the  following  solution  : 
Osmic  acid      0.455 
Glycerin    1420 
Distilled  water   24.60 
This  solution  should  be  kept  in  a  black  bottle  and  if  carefully  sealed 
will  keep  for  two  or  three  weeks. 
For  neuralgic  affections  five  drops  of  the  above  solution  are  injected 
hypodermically  near  the  seat  of  pain.  In  some  cases  the  injection 
must  be  renewed  but  does  not  produce  any  dangerous  results. — Jour- 
nal de  Pharm.  et  de  Chim.  1886,  xiv,  p.  519.  (See  also  Amer.  Jour. 
Phar.,  1884,  page  648.)
