were  purified  by  repeated  recrystallization  from  stronger  ether  and 
submitted  to  ultimate  analysis. 
Two  combustions  of  those  from  the  light  petroleum  ether  were 
made  with  the  following  results :

The  crystals  obtained  from  the  heavier  petroleum  ether  were 
purified  by  recrystallization  from  ether,  and  combustions  were 
made  at  different  periods  in  their  purification  without  finding  any 
change  from  the  above  composition.  It  is  likely  that  several  crys- 
tallizable  resins  are  present  in  the  crude  "  gum."  They  are  worthy 
of  much  further  investigation  which  could  not  be  completed  in  the 
time  at  my  disposal  for  this  work.

Professor  J.  Konig  refers  in  his  admirable  compilation  "  Chemische 
Zusammensetzung  der  menschlichen  Nahrungs-  und  Gcnussmittel," 
3te  Aufl.,  1889,  to  17  kinds  of  malt  extracts.    A  few  analyses  an 
old  and  none  is  American.    But  I  have  no  doubt  that  their  figures
