Treatment  with  Boiling  Water,  Table  No.  I. — 10  grams  of  pow- 
dered mate'  were  boiled  half  an  hour  with  100  cc.  of  water,  the  decoc- 
tion poured  off",  and  the  process  repeated  four  times  with  the  same 
quantity  of  water  ;  the  decoctions  were  mixed,  filtered,  and  evaporated 
on  a  water-bath  to  dryness.  The  extract  obtained  was  of  a  brown 
color  in  mass,  yellow  in  powder,  of  slight  odor  and  mild  bitter  taste. 
It  contained  caffeina,  tannin,  gum,  starch  and  pectin. 
The  extract  yielded  to  boiling  water  by  10  grams  of  mate  after  treat- 
ment as  in  Table  No.  II,  was,  when  powdered,  of  the  color  of  unburnt 
umber,  inodorous  and  tasteless  ;  it  consisted  principally  of  starch  and 
pectin.
