2d.  Free  solubility  in  water,  alcohol  and  ether. 
3d.  Yellow  color  upon  addition  of  alkalies. 
4th.  Non-alteration  in  aqueous  solution  by  H3P04,  H2S04  and  HC1, 
thereby  distinguishing  it  from  gallotannic  acid. 
5th.  Green-black  coloration  with  Fe2Cl6. 
The  dregs  left  after  exhaustion  of  the  bark  with  water,  being  dried 
and  reduced  to  powder,  were  exhausted  with  alcohol  by  percolation, 
and  yielded  a  resinous  tincture,  of  a  dark-red  color.  By  pouring  this 
into  a  large  quantity  of  distilled  water,  the  resin  was  copiously  pre- 
cipitated, and  when  collected,  washed  and  dried  was  of  a  brown  color 
and  almost  devoid  of  taste. 
One  gram  of  this  resin  treated  with  ether  lost  -65  gram,  showing 
that  ether  dissolved  of  it  nearly  two-thirds  by  weight. 
In  the  fixed  alkalies,  the  resin  was  entirely  soluble,  giving  a  deep- 
red  color,  from  which  solution  it  was  precipitated  by  acids. 
Five  grams  of  the  fresh  bark  lost,  by  careful  drying,  1*8  gram., 
showing  28  per  cent,  of  moisture. 
Examination  of  the  ash  from  a  portion  of  the  bark  showed  the 
following  constituents :  carbonic,  phosphoric,  sulphuric  and  hydro- 
chloric acids ;  calcium,  potassium,  sodium,  magnesium  and  iron. 
Summary. — From  the  foregoing  analysis  of  the  bark  of  the  root  of 
Madura  aurantiaca  its  constituents  may  be  said  to  be :  starch,  glu- 
cose, gum,  resin,  volatile  oil  in  minute  quantity,  moric  and  morintan- 
nic  acids. 
A  partial  examination  of  the  woody  portion  of  the  root  gave  evi- 
dence of  the  presence  of  coloring  matter,  though  seeming  in  much 
smaller  quantity  than  in  the  bark. 
A  VISIT  TO  SHAW'S  GARDENS. 
By  Richard  V.  Mattison,  G.  P. 
The  Missouri  Botanical  Gardens,  or  Shaw's  Gardens,  as  they  are 
familiarly  termed  by  the  citizens  of  St.  Louis,  are  situated  at  Shaw 
and  Tower  Grove  avenues.  A  few  days  since,  while  visiting  the  city 
on  business,  opportunity  was  given  the  writer  to  pay  a  visit  to  this 
beautiful  place,  and,  while  spending  a  pleasant  afternoon,  a  few  notes 
were  taken,  which  are  here  presented,  with  the  hope  that  they  will 
prove  interesting  enough  to  the  readers  to  cause  them,  when  visiting 
the  "  future  great"  city,  to  also  pay  a  visit  to  the  beautiful  gardens 
adjoining  Tower  Grove  Park.
