ness,  dissolved  in  water  and  again  distilled  with  sulphuric  acid  ;  the 
distillate  was  slightly  colored,  and  had  the  distinct  odor  of  valerianic 
acid  ;  this  was  neutralized  with  caustic  soda  and  evaporated  to  dryness. 
A  portion  of  the  resulting  valerianate  of  soda  was  dissolved  in  amylic 
alcohol,  sulphuric  acid  added,  and  heated,  when  the  characteristic  apple 
odor  was  developed.  An  aqueous  solution  of  valerianate  of  soda  and 
of  sulphate  of  zinc  were  heated  separately  and  then  mixed,  when,  on 
cooling,  crystals  of  valerianate  of  zinc  separated  in  white  pearly  crys- 
talline masses  ;  these  are  soluble  in  alcohol,  and  in  a  large  quantity  of 
water,  and  have  a  styptic  taste  and  an  acid  reaction,  turbid  when  heated, 
clear  on  cooling,  and  are  soluble  in  ammonia  water. 
Analysis  of  Ash. — Twenty  grams  of  the  bark,  in  powder,  were  care- 
fully dried  and  weighed  ;  total  weight,  i8'6  grams  ;  on  incinerating,  it 
was  found  to  weigh  1*65  gram  ;  on  percolating  with  water  and  drying, 
it  weighed  i'579  gram.  The  aqueous  percolate  gave  a  dense  white 
precipitate  with  solution  of  chloride  of  barium,  insoluble  in  boiling  nitric 
acid,  and  on  addition  of  water  the  precipitate  is  not  dissolved,  showing 
the  presence  of  sulphuric  acid.  With  solution  of  nitrate  of  silver  a 
curdy  white  precipitate  of  chloride  of  silver  was  obtained,  soluble  in 
ammonia,  insoluble  in  boiling  nitric  acid  ;  on  addition  of  perchloride 
of  platinum  to  the  original  solution  a  precipitate  of  potassium  was 
obtained. 
The  ash  was  percolated  with  dilute  solution  of  hydrochloric  acid, 
which  caused  it  to  effervesce,  showing  the  presence  of  carbonates ; 
the  ash  was  nearly  all  dissolved,  only  a  slight  portion  remaining  on  the 
filter.  The  filtrate  gave  a  copious  precipitate  with  ferrocyanide  of 
potassium,  showing  the  presence  of  the  ferric  salts  of  iron.  When 
ammonia  was  added  to  the  filtrate  it  became  cloudy,  and  clear  again  on 
addition  of  acetic  acid.  Ammonia  was  added  to  the  filtrate  to  precipi- 
tate the  iron,  filtered,  and  to  the  filtrate  solution  of  chloride  and  car- 
bonate of  ammonia,  boiled  and  filtered,  when  a  precipitate  was  formed. 
This  was  filtered,  washed  and  dissolved  in  acetic  acid  ;  this  gave  no 
reaction  with  chromate  of  potassium,  showing  the  absence  of  barium  ; 
but  with  oxalate  of  ammonia  a  white  precipitate  of  calcium  oxalate 
was  formed.  The  filtrate  gave  a  copious  precipitate  with  phosphate 
of  ammonia,  showing  the  presence  of  magnesium.  The  small  residue 
of  ash  remaining  undissolved  m  hydrochloric  acid  solution  under  the 
blow-pipe  only  gave  evidence  of  iron.
