the  alkali  extract  was  undetermined,  and  represented  14-03  per 
cent. 
VIII.  After  washing  free  from  the  alkali,  the  residue  was  treated 
with  acidulated  water  for  24  hours;  12-8  per  cent,  were  extracted 
from  this  solution,  which  consisted  of  inorganic  salts  and  starch. 
IX.  The  remainder  of  the  drug,  after  thoroughly  washing  and 
drying,  was  weighed  and  estimated  as  cellulose  and  lignin,  equalling 
43-2  per  cent. 
An  aqueous  infusion  was  made  with  one  gram  of  the  powder, 
and  tannin  estimated  with  copper  acetate,  which  gave  6-8 1  per  cent, 
the  total  amount  of  tannin  in  the  root.  The  total  albumen  as  esti- 
mated by  Kjeldahl's  method  was  2-375  Per  cent.

FABIANA  IMBRICATA. 
A  Plant  Analysis. 
By  Harry  C.  Loudenbeck,  Ph.C, 
Under  the  name  of  "  Pichi,"  Fabiana  imbricata  is  known  in  Chili 
and  Argentine  Republic  for  its  prompt  action  in  diseases  of  the 
kidney  and  liver. 
This  shrub  which  might  be  taken  for  a  conifer,  belongs  to  the 
natural  order  Solanaceae,  sub-order  Curvembryese  and  tribe  Nico- 
tianeae.  It  grows  on  high  and  dry  hill  tops,  and  is  remarkable  for 
its  light  bluish-green  branches,  which  are  covered  with  a  resinous 
matter,  that  hardens,  forming  a  gray  powder.  In  trade  Pichi  con- 
sists of  the  stems  and  leafy  branches  which  are  covered  with  a  thin 
gray  bark  to  which  a  considerable  resinous  matter  adheres.
