The Thorn-apple is found occafionally in the environs of London, on dunghills, in cultivated ground, and 
amono-fl rubbilh ; both Mr. Ray and Mr. Hudson place it amongft the Britilh plants, regarding it at the 
fame Time as a doubtful native ; following their example, we have figured it in the Flora Londinenfis, in- 
duced thereto from the additional confideration of its being a poifonous plant, and, as fuch, neceffary to be 
known to our readers. 
That it is a native of America, we have the mod indubitable proofs : in the earth brought with plants from 
various parts of that extenfive country, we are fure to have the Thorn-apple come up, which we {hall not 
wonder at, after perufing the following extratt from Kalm’s Travels into North-America. “The Datura 
“ Stramonium grows in great quantities in all the villages; its height is different according to the foil it is 
“ in : for, in a rich foil, it grows eight or ten feet high ; but, in hard and poor ground, it will feldom come 
up' to fix inches. This Datura, together with the Phytolacca, or American Nightlhade, grow here in thole 
•• places near the gardens, houfes, and roads, which In Sweden are covered with Nettles and Goofefoot, 
« which European plants are very fcarce in America ; but the Datura and Phytolacca are the worft weeds 
“ here, nobody knowing any particular ufe ol them.
