new  olive  oils — however,  pure — may  sometimes  give  a  red  color.  In 
taking  care  to  expel  the  water  from  the  fat  acids,  at  a  heat  of  110° 
[230°  F.]  and  pouring  them  into  a  test  tube  upon  an  equal  quantity 
of  HCl  j^sacch.),  the  rose  color  is  produced,  whatever  proportion  of 
sesame  may  be  present  in  the  olive  oil.  But  if  the  latter  be  pure,  the 
HCl  (sacch.)  remains  absolutely  colorless.  Union  Pharm.,  March,

Innoxiousness  of  Boracic  Acid.  Dr.  Gaucher  concludes  from 
experiments  upon  animals  that  man  would  have  to  take  75  gm.  in 
twenty-four  hours  to  get  its  toxic  effects.  To  several  tuberculous 
patients  he  gave  quantities  equal  to  1  gm.  daily.  After  a  few  days  of 
treatment  the  fetidity  of  the  sputa  disappeared,  and  in  two  cases  the 
general  condition  was  ameliorated.  He  found  it  beneficial  in  cystitis ; 
it  produced  no  gastric  irritation.  Soc.  mtd.  des  hdpitaux ;  Hepert.  de

GuAiACOL  is  recommended  by  Sahli  {J.  de  phar.  d^ Alc-Lo7^r.,  Jan- 
uary, 1888),  as  a  substitute  for  creasote,  owing  to  the  uncertainty  as  to 
the  purity  of  the  latter.  For  its  internal  administration  he  proposes 
the  following  formula:  Guaiacol,  2  gm.;  alcohol,  20  gm.;  water,  180 
gm.;  dose,  from  a  teaspoonful  to  a  tablespoonful  two  or  three  times  a 
day,  after  eating.    The  mixture  should  be  kept  in  black  glass. 
SozoiODOL  is  described  as  a  derivative  of  the  aromatic  series  having 
the  constitution  of  a  phenol  whose  atoms  of  hydrogen  are  replaced  by 
the  radical  (SO3H)  and  an  atom  of  iodine.  It  takes  the  form  of  a 
brilliant  crystalline  powder,  is  inodorous  and  dissolves  sparingly  in 
cold  water  and  in  cold  alcohol.  It  holds  42  per  cent,  of  iodine  and  is 
said  to  be  equally  efficacious  with  iodoform  and  salicylic  acid  in 
dermatoses.  It  appears  to  owe  its  only  advantages  to  its  absence  of 
odor.       ZJmW  P/iarm.  February,  1888. 
Anthrarobin,  discovered  by  Liebermann  (Berlin  Medical  Society) 
is  less  toxic  than  chrysarobin,  for  which  several  German  physicians 
wish  to  substitute  it.  Rabbits  absorb  1  gm.  without  inconvenience. 
It  is  eliminated  by  the  kidneys,  after  changes  not  yet  studied.  Doc- 
tors who  use  it  make  topical  applications  (in  the  form  of  unguents) 
against  psoriasis,  herpes,  pityriasis,  etc.,  or  employ  it  in  10  to  100  alco- 
holic solutions,  which  are  preferable.  The  ointments  consist  of  10  or 
20  to  100.    Its  efficaciousness  is  heightened  with  soap  and  water  after
