and  could  not,  by  the  careful  student,  easily  be  confounded  with 
them.  It  is  very  unusual  for  grains  so  minute  to  show  a  structure 
so  distinct,  particularly  for  the  hilum  and  micropyle  to  stand  out  with 
such  distinctness  as  they  do  in  the  cacao  starches.

*  This  list  of  tanning  materials  has  been  received  from  our  honorary  member 
at  Ootacamund,  India.  It  was  compiled,  and  the  percentages  of  tannin 
determined  by  him.  The  results  have  not  appeared  elsewhere,  except  in  his 
report  to  the  British  Government.  They  are,  therefore,  considered  especially 
desirable  for  placing  on  record  in  this  country. — Editor.
