dryness,  after  digestion  with  charcoal,  which  removed  much  of  the 
color.  The  residue  was  dissolved  in  absolute  alcohol,  filtered  from  a 
trace  of  reduced  silver,  and  again  evaporated  to  dryness,  and  the  dry- 
ing completed  in  an  air-pump  over  sulphuric  acid  during  a  fortnight. 
The  product  was  now  analyzed,  all  cumbustions  being  effected  in 
platinum  boats,  as  the  matter  was  soft  and  plastic,  like  gum.

After  the  above  analysis  was  completed,  the  rest  of  the  alkaloid 
was  dissolved  in  87  per  cent,  alcohol,  and  treated  with  alcoholic  platinic 
chloride,  when  a  bulky  precipitate  was  produced,  but  slightly  soluble  in 
cold,  readily  soluble  in  hot  water.  The  yellow  solution  on  concentra- 
tion gave  a  crop  of  reddish-yellow  octohedral  crystals,  which  were 
isolated,  rinsed  with  water,  dried  at  8o°  C,  and  analyzed.
