slight  terebinthinate  odor  and  taste,  and  being  soluble  in  ether  and 
chloroform.  Residue  of  extract  was  agitated  with  chloroform,  and 
allowed  to  stand  48  hours.  A  thin,  slightly  green  layer  separated  at 
bottom,  which,  upon  separation  and  subsequent  evaporation,  yielded 
a  small  amount  of  a  light-greenish  tenacious  mass,  resembling  the 
glucoside  very  much  in  taste,  but  differing  from  it  by  its  solubility  in 
chloroform  and  not  being  readily  pulverized.  To  the  remaining  tur- 
bid chloroform  mixture,  alcohol  of  -817  was  added  in  excess  (3  to  1)  ; 
the  sugar  was  precipitated,  taking  with  it  some  of  the  glucoside.  This 
was  separated  by  repeated  solution  in  alcohol  -817  and  precipitated 
by  ether,  the  ether  and  alcohol  holding  the  glucoside  in  solution,  the 
sugar  precipitating.  The  yield  of  cane  sugar  and  syrup  was  2J  per 
cent.  Upon  evaporating  the  alcoholic  and  ethereal  solution,  the  glu- 
coside was  obtained  in  light  yellowish-brown,  shining  scales,  possess- 
ing a  peculiar,  heavy  odor  and  an  extremely  bitter  and  acrid  taste, 
with  a  peculiar  and  lastingly  drying  effect  in  the  fauces.  This  glu- 
coside, by  boiling  with  dilute  hydrochloric  acid,  was  converted  into  glu- 
cose, and  a  compound,  which,  by  solution  in  alcohol,  was  obtained  in 
small  yellowish-white  crystals,  devoid  of  odor  and  taste,  but  having 
an  acid  reaction.  The  glucoside  is  insoluble  in  ether  and  chloroform, 
soluble  in  alcohol,  more  in  hot ;  freely  soluble  in  water,  yielding  a  frothy 
solution  acid  to  litmus.  By  distilling  with  B2S04H20,  a  solution  of 
valerianic  acid  was  obtained,  which  was  carefully  neutralized  with 
NaHO,  evaporated,  and  yielded  a  small  quantity  of  salt.  A  portion 
of  this  mixed  with  a  drop  of  amylic  alcohol  and  H2S04  in  excess, 
yielded,  upon  the  addition  of  a  drop  of  water,  the  odor  of  apple  oil  or 
valerianate  of  amylic  ether. 
3.  The  residue  (from  alcoholic  percolator)  was  dried  and  exhausted 
with  cold  water,  the  infusion  treated  with  lead  acetate,  the  precipi- 
tate washed  and  the  lead  thrown  out  by  H2S  and  filtered.  The  filtrate 
was  rejected;  the  residue  on  filter  dried,  reduced  to*a  fine  powder, 
and  exhausted  by  washing  with  cold  alcohol  of  -817.  The  alco- 
holic solution  was  heated  and  filtered,  the  filtrate  shaken  with  a  small 
portion  of  chloroform  to  remove  the  coloring  matter  which  floated  on 
the  top  of  the  solution,  and  separated  by  filtration  ;  filtrate  concen- 
trated and  crystallized,  obtained  a  minute  crop  of  light  yellowish-white 
prismatic  crystals,  soluble  in  alkalies,  not  in  acetic  acid,  possessing  a 
decided  acid  taste  and  reaction,  and  totally  volatilized  by  heat. 
4.  The  residue  left  of  the  cotyledons  was  washed  with  successive
