The  behavior  of  the  oils  of  cinnamon,  cubeb,  juniper,  lemon,  orange, 
peppermint  and  tansy  under  the  above  circumstances  seems  to  deserve 
attention.  Except  in  a  few  instances,  violet  and  orange-colored  vapors 
"were  evolved  during  the  reaction.  The  reactions  were  increased  in  the 
presence  of  oil  of  turpentine  and  diminished  with  alcohol. 
CHLORINATED  OIL. 
By  L.  Wolff,  M.D. 
Under  the  above  title  I  read,  at  the  pharmaceutical  meeting  of  May 
€th,  a  paper  which  was  printed  in  the  June  issue  of  the  American 
•Journal  of  Pharmacy,"  and  which  at  the  time  I  thought  to  be  the  first 
account  of  this  preparation,  although  I  made  no  claim  to  that  effect. 
That  there  seems  to  be  nothing  new  under  the  sun  is  in  this  instance 
again  very  striking,  for  Prof.  Maisch  called  my  attention  recently  to  a 
letter  from  Mr.  Hans  Wilder,  stating  that  in  the  German  edition  of 
Jourdan's  "Pharmacopoeia  universalis"  of  1846  this  matter  had  already 
been  printed.    I  reproduce  it  here  to  show  how  close  alike  was  my 
own  effort  to  that  of  yore,  although  I  need  hardly  assure  here  that  my 
experiments  were  altogether  independent  and  without  knowledge  of 
earlier  ones  on  this  subject.    I  quote  from  the  "Pharmacopoeia  uni- 
versalis," second  edition,  London,  published  by  Joseph  Robins,  1833, 
vol.  I,  page  460,^  as  among  the  chlorine  preparations : 
"Oil  witli  Chlorine.

R    Olive  oil,       .       .       .       .       .       .       .16  oz. 
"Put  it  into  a  large  receiver,  surround  with  cold  water  or  snow,  and  pass 
through  it  a  current  of  gas,  disengaged  from  a  mixture  of  one  pound  of 
muriate  of  soda,  four  ounces  of  oxide  of  manganese,  and  half  an  ounce  of 
sulphuric  acid  diluted  with  water.  At  the  end  of  two  or  three  days,  wash 
with  water  and  preserve  it. 
"  It  is  recommended  by  Nieman  in  tinea  and  herpetic  ulceration." 
As  my  paper  did  not  claim  as  novelty  the  combination  of  chloriue 
with  oils,  but  rather  the  exposition  of  how  they  combine,  I  think  its 
value  none  the  less,  especially  as,  judging  from  the  name  of  the  older 
product,  its  chemical  composition  was  certainly  not  understood ;  nor 
have  I  })een  able  to  find  anything  in  literature  illustratiug  or  explain- 
ing the  chlorine  compounds  with  fat  oils. 
1  The  formula  was  also  published  in  the  original  French  edition  of  Jour- 
dan's  work  of  1828.
