; Sept. 10, 1890, in Amer. Journ. Pharm., Oct. 1890. The air- 
dried seeds of D. fastwosa ( purple var. ) reduced to powder 
Jost 7:828 per cent. of moisture when heated to 100° C. 
The ash calculated on the air-dried seeds amounted to 4°830 
per cent., and was of a brick- red colour. 
On proximate analysis the following results were obtaitied,
