ether ;  on  evaporating  the  solvent  a  granular  extract  was  left,  which 
became  purple  by  alkalies  from  the  presence  of  yellow  coloring  mat-

Eriodictyon  calif  or  nicum,  Bentham. — An  analysis  of  the  leaves 
yielded  to  Oliver  F.  Lenhardt,  Ph.  G.,  7*6  per  cent,  of  moisture,  and 
4*25  per  cent,  (or  for  the  anhydrous  drug  5'14  per  cent.)  of  ash.  Of 
the  latter  26 '66  per  cent,  was  soluble  in  water,  63*4  per  cent,  soluble 
in  HC1,  and  3'5  per  cent,  soluble  in  solution  of  KHO.  Petroleum 
benzin  extracted,  including  volatile  oil,  2'63  per  cent.,  of  which  '39 
was  wax  which  separated  from  hot  alcohol  amorphous  and  melted  at 
61  °C.  With  ether  15*3  per  cent,  of  extract  was  obtained,  of  which 
three-fifths  (9  per  cent.)  was  a  brittle,  fragrant,  and  slightly  acid  resin 
soluble  in  80  per  cent,  alcohol ;  a  little  tannin  was  also  present,  and 
the  green  tenacious  residue  was  partly  soluble  in  benzol,  and  entirely 
soluble  in  carbon  disulphide,  and  in  chloroform ;  alkaloids  and  gluco- 
sides  were  absent.  The  exhausted  leaves  yielded  to  absolute  alcohol 
3*64  per  cent,  of  extract,  fully  one-third  of  which  was  soluble  in  water, 
among  other  constituents  tannin  and  a  glucosidal  compound  being  dis- 
solved. The  watery  extract  of  the  exhausted  leaves  weighed  22 '3  per 
cent,,  was  of  a  brown  color,  had  a  pleasantly  sweetish  and  somewhat 
acrid  taste,  and  contained  tannin. 
Lycopus  virginicus,  Lin. — Sherman  F.  Hennessy,  Ph.  G.,  ex- 
perimented with  air  dry  bugle  weed,  containing  9  per  cent,  of  mois- 
ture. Cold  water  dissolved  10*4  per  cent,  of  constituents,  consisting 
of  albuminoids,  gummy  matter,  a  little  tannin,  and  extractive.  Alco- 
hol now  took  up  12*8  per  cent,  of  chlorophyll,  resin,  bitter  extractive, 
etc.  A  small  quantity  of  a  lemon-yellow  volatile  oil  was  obtained  by 
distilling  the  herb  with  water. 
Stigmata  Maydis. — John  Rea,  Ph.  G.,  determined  in  the  cold 
water  infusion  of  corn  silk  (fresh  ?)  the  sugar  by  means  of  Fehling's 
solution,  which  indicated  0.88  per  cent.  ;  after  boiling  the  infusion 
for  one  hour  with  hydrochloric  acid,  1*42  per  cent,  of  sugar  was 
found. 
Commercial  Kino. — Chas.  H.  Breidenbach,  Ph.  G.,  examined  five 
samples  of  Malabar  kino  and  four  samples  of  poAvdered  kino,  of 
which  F  and  G  were  odorless  and  had  a  red-brown  color,  while  H 
and  I  had  a  slight  aromatic  odor  and  a  very  dark-red  grayish-brown 
color,  and  yielded  a  gray-brown  ash,  that  of  the  other  samples  being 
white.    The  results  are  as  follows  :
