An enquiry into the nature of the poison of an Arabian vetch (Lotus arabicus). 
This was proved to be due to prussic acid formed from a new glucoside present in this 
plant, which has been named lotusin (see Addendum). Phis glucoside disappears as the 
seeds ripen, when the plant becomes non-poisonous and can be used as fodder.

Stramonium grown in Egypt (see Addendum). Both these plants, the former especially, 
aie shown to be valuable commercial sources of the alkaloid hyoscyamine and are now
