SAMBUCUS  CANADENSIS. 
C.  Otto  Moosbrugger,  Ph.G.,  made  a  chemical  investigation  of  the 
bark  of  this  member  of  the  Caprifoliaceae,  whose  flowers  are  official. 
The  bark  is  said  to  be  used  as  a  poultice  for  "  foot  rot "  in  cattle. 
When  subjected  to  analysis  it  was  found  to  contain  :

YUCCA  FILAMENTOSA. 
Max  Morris,  Ph.G.,  having  heard  that  a  tincture  of  the  root  of 
this  plant,  which  is  called  "  bear  grass  "  in  the  southern  part  of  the 
United  States,  had  been  used  internally  in  the  treatment  of  rheuma- 
tism, decided  to  investigate  the  drug  chemically.  He  accordingly 
collected  some  of  the  root  near  Macon,  Ga.,  and  subjected  it  to  a 
proximate  analysis.  Wax,  fat  and  caoutchouc  were  found  to  con- 
stitute the  petroleum  ether  extract.  Ether  removed  a  small  amount 
of  a  resin  which  gave,  with  ferric  chloride,  a  brown  precipitate,  and 
with  lead  acetate  a  brownish-white  precipitate.    Absolute  alcohol
