Poisonous and Medicinal Plants. 
An enquiry into the nature of the poison of an Arabian vetch (Lohis arabicits). 
This was proved to be due to prussic acid formed from a new glucoside present in this 
plantj which has been named lotusin (see Addendum). This glucoside disappears as the 
seeds ripen, when the plant becomes non-poisonous and can be used as fodder. 
An examination of the alkaloid contained in Hyoscyamus muticus and Datura 
Stramomzim grown in Egypt (see Addendum). Both these plants, the former especially, 
are shown to be valuable commercial sources of the alkaloid hyoscyamine and are now 
being exported to this country.
