The  author  found  it  impossible  to  obtain  the  whole  amount  of 
filicic  acid  present  suitable  for  quantitative  determination.  Rhizomes 
collected  in  September,  1875,  gave  results  in  extracts  and  in  the  com- 
position of  the  ashes,  agreeing  closely  with  the  results  obtained  from 
the  October  rhizome.  The  ashes  contain  between  19  and  20  per 
cent,  of  phosphoric  acid,  10  to  11  per  cent,  silica,  5*5  per  cent,  sul- 
phuric acid,  and  some  chlorine  and  carbonic  acid,  combined  with  potas- 
sium, calcium,  magnesium,  iron,  manganese  and  sodium. — Archiv  cL 
Phar.,  1876,  July,  24-32. 
Pyrethrum  carneum. — According  to  Joussel  de  Bellesme,  the 
poisonous  properties  of  the  insect  powder  is  not  due  to  the  volatile  oil, 
but  to  a  crystalline  principle  which  he  considers  to  be  an  alkaloid, —

The  oils  of  the  aurantiaceae  (lemon,  bergamot  and  orange)  deposit, 
on  standing,  a  white  sediment,  which  frequently,  perhaps  always,  con- 
tains lead.  Dannenberg,  who  confirms  this  observation  of  G.  Buch, 
made  in  1846,  has  as  yet  not  been  able  to  collect  a  sufficient  quantity 
of  the  precipitate  to  determine  the  nature  of  the  acid  with  which  the 
lead  is  combined. — Archiv  d.  Phar.,  Sept.,  1876,  258.
