The alkaline principle obtained by Brandes from the seeds — 
: of No. 221, similar to Atropia and Hyoscyama. Daturia 
ts © contains the poisonous principle Stramonium, and 
should therefore be cautiously prescribed. Brandes has 
: furnished an imperfect account of this substance; and it 
‘ "yet remains to be ascertained, in how far it ma ‘be an ac- 
cession to the list of medicines. An i rtation 
on this subject, if carefully executed, experiments, 
would give its author much credit. I subjoin Brandes’, 
analysis of the seeds of Stramonium :— 2 ;
