forests,  which  are  the  source  of  a  most  important  industry,  whose  prin- 
cipal centre  is  in  the  Villa  de  San  Xavier. 
The  appearance  and  character  of  the  samples  indicate  that  there  are 
at  least  three  sorts  of  powdered  mate.  First,  that  made  from  the 
young  leaves  3  samples  Nos.  1  and  2  appear  to  be  of  this  sort.  Second, 
that  prepared  by  the  original  primitive  method  of  the  natives,  and  which 
exceeds  both  of  the  other  kinds  in  aromatic  properties  ;  of  this  sort 
Nos.  3,  4,  5  and  6  appear  to  be  samples.  Third,  that  prepared  with 
more  care  and  with  the  aid  of  modern  furnaces  for  its  torrefaction,  and 
mills  for  its  pulverization  ;  of  this  sort  No.  7  appears  to  be  a  sample. 
The  following  experiments  were  all  performed  with  the  utmost  care, 
the  method  of  examination  adopted  was  uniformly  applied  to  all  the 
samples,  the  air-dried  mate  was  in  each  case  powdered  and  kept  in  a 
well  stoppered  bottle,  to  be  drawn  from  as  required.  The  results 
shown  by  the  first  table  were  obtained  by  subjecting  10  grams  of  mate 
to  the  separate  action  of  each  of  the  different  solvents  and  processes 
as  there  shown.  The  results  shown  by  the  second  and  third  tables 
were  obtained  by  treating  10  grams  of  mate  successively  with  the  sol- 
vents in  the  order  there  given,  the  difference  being  that  in  the  second 
table  the  mate  is  last  treated  with  boiling  water,  and  in  the  third  table 
that  solvent  is  the  first  to  which  it  is  subjected.
