Remarks by Mr. William Watfon, F. R . S. 
Upon reading the above paper, Mr. Watfon obferv’d, 
that the effects therein mentioned could not arife 
from the hyofcyamus dibits , or white henbane, as Dr. 
Stedman imagines ; that plant, from the concurrent 
teftimony of the beft botanical writers, not being 
found fo far north as Brabant : but the mifchief was 
done by the hyofcyamus niger , or black henbane, 
which grows plentifully there, as well as almoft all 
over Europe in uncultivated places, and by the tides of 
roads. The white on the contrary is fown in gar- 
dens, and not found fpontaneous in higher latitudes 
than the fouthern parts of France. 
Dr. Stedman’s defcription demonftrates Iikewife 
the above plant to be the hyofcyamus niger , as he 
fays, that <c it is known by its dufkifh bell-flower.’* 
The flower of black henbane is of that hue, being 
of a yellow colour interfperfed with veins of purple; 
whereas the flower of the white henbane is of a 
pale-yellow colour. 
This error arifes from the improper denomination 
Impofed upon many plants by the ancients, and 
which has been preserved even flnce the revival of 
letters ; which, to one not very well acquainted with 
botany, is liable to miflead. Thus, in the cafe be- 
fore us, the leaves of the black henbane are very 
little lefs white than thofe of the white ; but this 
denomination took its rife from the different colour 
of their feeds. In fuch cafes therefore, without
