Chamomile  Flowers. — On  exhausting  the  flower  heads  of  Anthemis 
nobilis  with  petroleum  benzin,  Ella  Amerraan,  Ph.  G.,  obtained  a 
green  wax,  which  after  six  recrystallizations  from  alcohol  was  nearly 
white,  bitter  and  crystalline,  and  melted  at  about  130°  C.  On  ex- 
hausting the  drug  now  with  ether,  and  treating  this  extract  again  with 
ether,  as  recommended  by  Camboulises  in  1871,  a  crystalline  sub- 
stance, distinctly  acid,  and  of  a  glucosidal  nature  was  obtained.  A 
small  quantity  of  similar  crystals  was  also  obtained  by  Werner's  pro- 
cess (1867)  by  exhausting  with  dilute  acetic  acid,  concentrating,  pre- 
cipitating with  alcohol,  treating  with  chloroform,  evaporating,  ex- 
hausting with  ether  and  treating  this  extract  with  warm  distilled 
water.  In  a  third  experiment  the  alcoholic  tincture  of  the  flowers 
was  concentrated,  precipitated  by  water,  the  filtrate  treated  with 
chloroform,  the  solvent  evaporated  and  the  residue  treated  with 
water.  The  aqueous  solution  of  the  crystals,  on  being  boiled  with 
hydrochloric  acid,  became  opalescent,  emitted  a  honey-like  odor, 
and  with  Fehling's  solution  now  gave  evidence  of  the  presence 
of  glucose.  There  was  no  evidence  of  the  presence  of  an  alka- 
loid. 
Diospyros  virginiana,  Lin. — The  bark  of  this  tree  is  of  a  tan  color, 
and  has  a  mucilaginous  bitterish,  then  swreetish  and  astringent  taste. 
Experiments  made  by  Frank  E.  Murphy,  Ph.  G.,  gave  the  following 
results :  The  powdered  bark  yielded  to  petroleum  benzin  0'9  per 
cent,  of  an  amber  colored  extract,  free  from  volatile  oil.  Ether  took 
up  1*4  per  cent.,  the  extract  yielding  to  alcohol  a  wine  colored  mass, 
which  deposited  from  chloroform  in  stellate  or  granular  crystals.  The 
alcohol  extract  of  the  bark  amounted  to  2*5  per  cent,  and  was  partly 
soluble  in  water.  The  water  extract  weighed  12  per  cent,  and  con- 
tained mucilage  and  dextrin.  The  extracts  thus  far  obtained  yielded 
a  purple  color  with  alkalies,  the  reaction  being  due  to  yellow  coloring 
matter.  On  treating  the  exhausted  bark  with  weak  solution  of  soda, 
the  mixture  also  acquired  a  deep  purple  color,  and  ultimately  became 
gelatinous.  The  acid  infusion  of  the  residuary  bark  gave  with 
ammonia  a  purple  colored  precipitate ;  calcium  oxalate  was  not 
found. 
A  quantity  of  the  partially  ripe  fruit  was  dried  and  treated  with
