guilder  (nearly  50  cents)  for  the  hundred  weight;  the  earth  is  also  exported  to  a 
considerable  extent  for  the  same  purpose.  By  dropping  a  pinch  of  the  suspected 
anise  upon  white  paper,  from  the  height  of  about  twelve  inches,  the  adulteration  is 
readily  detected,  and  its  amount  may  be  approximately  ascertained  by  picking  out 
the  fruit. — Apoth.  Zeitung,  No.  20. 
Vanillin  from  Eugenol. — E.  Erlenmeyer  announces  that  on  treating  eugenol- 
potassium  with  potassium  permanganate  (and  it  seems  as  if  the  same  result  was 
obtained  with  potassa  alone),  vanillin  may  be  obtained.  During  the  action  a  crys- 
tallizable  polymer  of  eugenol  is  formed.  After  the  completion  of  his  researches, 
the  author  will  report  the  results  in  detail. — Ber.  d.  Cbem.  Ges  ,  1876,  273. 
Eucalyptus  globulus. — P.  A.  Hartzer  has  obtained  the  following  principles, 
from  old  leaves  :  an  acid  resin  yielding,  with  sulphuric  acid,  a  copulated  acid  of  a 
handsome  carmine  color,  becoming  violet  on  the  addition  of  ether  5  two  resins, 
which  are  not  colored  red  by  sulphuric  acid  ;  a  new  fatty  acid,  crystallizing  in  fine 
needles,  the  sodium  and  potassium  salts  of  which  are  soluble  in  ether;  cerylic  or  a 
similar  alcohol  and  tannin.  The  latter  yields  a  red  deliquescent  crystalline  salt  on 
treating  the  etherial  solution  of  the  alcoholic  extract  with  a  solution  of  potassa  in 
absolute  alcohol. — Ibid.y  314-316. 
Pittakal,  which  was  discovered  by  Reichenbach,  40  years  ago,  but  has  not  been 
observed  since,  has  been  recentlv  obtained  by  Gratzel,  from  the  fractions  of  wood 
tar  having  a  high  boiling  point.  Liebermann  separated  from  it  orange- colored 
needles,  which  he  names  eupitton.  They  dissolve  in  alcohol  and  acetic  acid  with  a 
brown,  in  ammonia  with  a  blue  and  in  alkalies  with  a  purple  color  ;  carbonic  acid, 
or  the  addition  of  saline  solutions  causes  blue  precipitates  which  are  soluble  in  pure 
water,  the  precipitates  by  calcium,  magnesium,  barium  and  tinsalts  usually  having 
a  beautiful  gold  lustre.  The  lead  precipitate  dissolves  in  concentrated  sulphuric 
acid  with  a  red  color,  which  changes  to  blue  on  warming.—  Ibid ,  334-337. 
Naphthalin  from  Oil  of  Turpentine. — By  passing  oil  of  turpentine  through 
a  red-hot  tube,  G.  Schultz  observed  that  much  carbon  was  separated,  and  hydrogen 
evolved,  the  distillate  containing  several  hydro-carbons.  On  redistilling  the  pro- 
duct, the  portion  obtained  between  230  and  2320  C.  congealed,  and,  after  filtering 
and  pressing,  between  bibulous  paper,  yielded  naphthalin,  which  crystallized  from 
alcohol,  fused  at  300  C.  (1760  F.),  boiled  at  2170  C.  (422*6°  F.)  and  furnished  with 
picric  acid,  a  compound  crystallizing  in  yellow  needles  and  fusing  at  149°  C. 
(300*2°  F.). —  Ber.  d.  Deutsch.  Chem.  Ges.,  1876,  p.  548. 
A  New  Glucoside  in  the  Flowers  of  Cichorium  Intybus  has  been  dis- 
covered by  Dr.  R.  Nietzki.  The  flowers  were  extrated  with  boiling  60  per  cent,  alcohol 
the  alcohol  evaporated  in  the  presence  of  water,  the  filtrate  slightly  acidulated  with 
acetic acid,and  precipitated  by  acetate  of  lead.  The  clear  filtrate  was  treated  with  sul- 
phuretted hydrogen,  and  then  evaporated  to  a  thin  syrup,  from  which  the  body  crys-
